The same question on how to decrease salinity of lake has been well analyzed in both passage and lecture. In the passage, three solutions, including, removing salt, diluting and seperatingseparating(misspelling) lake, has been elaborated. However, the professor in the lecture contradicts that all these methods are not useful.

Firstly, the writer points out that salt in the lake can be directly removed by pumping and heating. Nevertheless, the speaker refutes that toxic chemicals could be generated in such process. In detail, she contends that when the water of lakethe lake(This rule identifies whether the article 'the' is missing in a sentence.) is heating, some solid matter is left, which contains both salt and toxic matters. Toxic matters are transmitted with air and harmful for people's health.

Secondly, the reading states that diluting lake's water by ocean water is plausible. However, the listening disapproves that it is too expensive to transport water from the ocean to the lake. To delve further, she maintains that the lake is 100 km far away from the ocean, which means that building longa long(This rule identifies whether the article 'a' is missing in a sentence.) pipeline takes lots of money. GovermentGovernment(misspelling) can not afford for this infrastructure.

Lastly, the passage conveys the point that the lake could be divided into small sections that isare(Detects potentially wrong usage of "is") easy to control salinity. Yet, the lecture contradicts that dividing is not a long useful plan. She advances the theory by saying that walls for dividing the lake will collapse if meet earthquake or other intense earth's activities. In this case, the effort before would be wasted and water from main section will flow to other section with high salinity.

Hence, the speaker completely disagrees with the opinions expressed in the reading.

Section Title: 6.文章修订

The issue of decreasing the salinity of the lake is thoroughly analyzed in both the passage and the lecture. The passage elaborates on three potential solutions: direct salt removal, dilution with ocean water, and dividing the lake into separate sections. However, the professor in the lecture contends that none of these methods are practical or effective.

Firstly, the author suggests that salt can be removed from the lake by pumping and heating its water. The lecturer, on the other hand, argues that this process could generate toxic chemicals. Specifically, she explains that when lake water is heated, solid matter containing both salt and toxic substances is left behind. These toxic substances can become airborne and pose a threat to human health.

Secondly, the passage posits that diluting the lake's water with ocean water is a viable solution. Nevertheless, the speaker refutes this idea by highlighting its high cost due to transportation challenges. She emphasizes that since the lake is located 100 km away from the ocean, constructing a long pipeline or canal system would be prohibitively expensive for local government resources.

Lastly, while the passage proposes dividing the lake into smaller sections to better control salinity levels, the lecturer disputes this as a long-term solution. She reasons that any walls built for this purpose would likely collapse during earthquakes or other intense geological activities common in that region. Consequently, previous efforts would be wasted as water from different sections with varying salinity levels would mix again.

In conclusion, the speaker strongly disagrees with all of the solutions presented in the reading passage due to their impracticality and potential negative consequences. (273 words)

The debate regarding decreasing the salinity of the Salton Sea is addressed by both the author and the professor. In the reading passage, the author presents three solutions for desalination. Nevertheless, the professor effectively casts doubt on each solution made in the reading passage by providing alternative perspectives and highlighting potential negative consequences, indicating it is neither practical nor realistic. To begin with, in contrast to the author’s claim in terms of the direct removal of salt from the Salton Sea’s water by means of desalination facilities, the professor contends that it will present serious problems, specifically health risks. In detail, he points out the wind is going to bring toxic chemicals into the air, which are formed through water evaporating. Consequently, people breathe the polluted air in, leading to health problems. Moreover, the professor further challenges the author’s assertion that it is effective to dilute the salt level with water, using pipelines and canals. He argues that although it may work out, the expanse of constructing pipelines and canals is prohibitive, which the government could not pay for. In addition, the expanse of construction for such a long distance, 100 kilometers, to be more specific, is costly. Furthermore, while the author implies the way of constructing walls to separate the lake into several sections to control the salinity, the professor presents a dissenting view. He emphasizes that it is unlikely to work for a long time because there are frequent geological activities in the region, such as earthquakes, which are able to destroy the walls easily. As a result, the dividing walls are only effective for a short while before they collapse due to earthquakes.

Lastly, while the author suggests constructing walls to divide the lake into several sections as a means of controlling salinity levels, the professor presents a dissenting view. He emphasizes that this solution is unlikely to be effective long-term due to frequent geological activities in the region, such as earthquakes. Consequently, even if dividing walls were built successfully initially, they would likely collapse during an earthquake and render this solution ineffective in controlling salinity levels.

In light of these counterarguments presented by the professor during his lecture, it becomes evident that each of these proposed solutions has significant drawbacks or limitations that make them impractical or unrealistic for addressing salinity issues in California's Salton Sea. (283 words)

In the lecture, the professor casts doubts on several solutions to reduce the salinity in Salton Sea mentioned by the reading passage. The professor asserts that these solutions are not realistic or practical at all. Firstly, contrary to the belief in the passage that salt in the lake can be removed directly by heating the water to leave salt and other materials behind, the professor asserts that this practice could result in serious problems because those materials left behind including some toxic chemicals, if spread into other areas and breathed in by people, would be dangerous to people's health. Secondly, the author of the passage points out that ocean water could be delivered through pipelines or canals to dilute the salt level, while the lecture notes that the governments don't have enough resources to bulidbuild(misspelling) the device because it is too expensive to establish such long pipelines or canals, over 100 kilometers, (Two consecutive spaces)between Pacific Ocean and Salton Sea. Lastly, opposing the author's belief that constructing walls to divide the lake into several sections could control the lake's salinity, the professor contends that this solution would just work in a short period, considering the lake is located in the region where geographic activities like major earthquakes happen frequently, posing a significant threat towards the walls.

6.文章修订

The lecture casts doubt on the solutions proposed in the reading passage for addressing the increasing salinity of the Salton Sea in California. The reading passage suggests three potential solutions: desalination, bringing ocean water into the lake, and dividing the lake into sections with walls. However, the lecturer argues that these solutions are not realistic or practical due to various reasons.

Regarding the first solution of desalination, the lecturer contends that this method would pose significant health risks. Although desalination would reduce salinity by evaporating water and leaving behind solid materials, it would also produce toxic chemicals such as selenium. These hazardous substances could be dispersed by wind and inhaled by people, causing serious health issues.

The second solution proposed in the reading passage involves diluting the lake's salt levels with ocean water delivered through pipelines or canals. The lecturer disputes this solution by highlighting its financial impracticality. Constructing pipelines or canals over long distances would be prohibitively expensive, and it is uncertain whether local governments possess sufficient resources to fund such a project. Furthermore, the nearest shoreline of the Pacific Ocean is 100 kilometers away, exacerbating construction costs.

Lastly, the reading passage suggests controlling salinity by constructing walls to divide the lake into several sections. In smaller sections, salinity would be allowed to increase while freshwater from nearby rivers would flow into a larger main section to maintain lower salinity levels. The lecturer challenges this solution due to its vulnerability to geological activity in the region. Earthquakes are frequent occurrences near Salton Sea; thus, any constructed walls are likely to collapse during seismic events, causing high-salinity water from smaller sections to mix back with low-salinity water in the main section.

In summary, although well-intentioned, each of these proposed solutions faces significant challenges as presented by the lecturer. Desalination raises health concerns due to toxic chemicals produced in the process, bringing ocean water into the lake is financially impractical, and dividing the lake with walls is vulnerable to the region's geological activity. Consequently, alternative solutions must be explored to address the Salton Sea's increasing salinity and preserve its fish and bird populations. (353 words)

Improved sentence: "However, the speaker challenges this notion by stating that after pumping and heating the salty water, the salt left behind might contain toxic chemicals."

Example 2: Original sentence: "The speaker disputes this method by arguing that it is too expensive for the local government to build constructions to pump water from the Pacific Ocean because the distance is over 1000 kilometers away from the lake and the government cannot built such long pump way." Improved sentence: "The speaker disputes this method by arguing that it would be too expensive for the local government to construct pipelines or canals to pump water from the Pacific Ocean due to its distance of over 100 kilometers from the lake."

4.Essay structure and organization

The essay has a clear structure with an introduction, body paragraphs addressing each solution separately, and a conclusion. However, some transitions between ideas could be improved for better coherence and cohesion.

Example 1: Original transition: "Firstly, ... Secondly,... Lastly,..." Improved transition: "Firstly,... In addition,... Finally,..."

Example 2: Original paragraph structure (with no clear topic sentence): "Secondly, ... The speaker disputes this method ..."

5. Grammar

The reading passage outlines three ways to reverse the trend (Two consecutive spaces)that the lake become too salty for fish and bird to live in, while the lecture refutes each of them sequentially. Firstly, the passage claims through the action directly removing salt from lake's water with special equipments and making water evaporate would solve the problem. However, the speaker challenge this notion, stating that after pumping and heating salty water, salt left behind might be toxic chemicals. If wind bring them into the air, they would be danger to the health. Secondly, the passage asserts that another possible solution is to dilute the salt level in the lake with water from the ocean as water in the ocean is 2o percent less salty than lake's water, decreasing the salinity of the lake. The speaker disputes this method by arguing that it is too expensive for the local government to build constructions to pump water from the Pacific Ocean because the distance is over 1000 kilometers away from the lake and the government cannot builtbuild(Non-infinitive verb after modal verbs) such long pump way. Lastly, the reading states that controlling lake's salinity with walls in several places can stop the trend continuing. The walls allow salinity in small area increase, while the salinity would be controlled in most large sections. Contrarily, the speaker maintains that the wall can't work long due to frequency and intense earthquakes which would damage the walls and water would run back into the main section.

6. Revised Essay

The reading passage presents three potential solutions to prevent the Salton Sea from becoming too salty for fish and bird populations to survive, while the lecture casts doubt on each of these proposals.

Firstly, the passage suggests that directly removing salt from the lake's water using special desalination facilities could resolve the issue. However, the speaker challenges this idea, arguing that after pumping and heating the salty water, toxic chemicals might be left behind along with the salt. If wind carries these chemicals into the air, they could pose a significant health risk.

Secondly, the passage proposes diluting the lake's salt levels with ocean water as a viable solution since ocean water is 20 percent less salty than lake water, thus decreasing salinity. The speaker disputes this method by pointing out that constructing pipelines or canals to transport water from the Pacific Ocean would be prohibitively expensive for local government due to its distance of over 100 kilometers from the lake.

Lastly, according to the reading, controlling salinity by constructing walls in several areas could halt this detrimental trend. These walls would allow salinity to increase in smaller sections while being controlled in larger areas. In contrast, the speaker asserts that such walls would not be effective long-term due to frequent and intense earthquakes in the region which could damage them and cause high-salinity water to mix back into main sections of the lake.

Section Title: 6.文章修订

The increasing salinity of the Salton Sea, resulting from water evaporation, is a concern for both the author and the lecturer. In the reading passage, three potential solutions are proposed: desalination facilities, diluting with ocean water, and constructing walls to divide the lake. However, the lecturer casts doubt on these solutions as being impractical.

Contrary to the desalination solution presented in the reading passage, the lecturer highlights that solid materials left behind during this process could pose health risks. Specifically, toxic substances such as selenium may be released into the atmosphere and cause respiratory health issues when inhaled.

Furthermore, the lecturer challenges the feasibility of diluting lake water with ocean water due to high costs associated with this approach. She emphasizes that constructing pipelines or canals over long distances (at least 100 kilometers) would require significant financial resources that may not be available to local governments.

Lastly, the lecturer disputes the effectiveness of building walls to divide sections of the lake as a long-term solution. She argues that since Salton Sea is located in an area prone to frequent geological activity like earthquakes, these walls would likely be destroyed by such events. Consequently, water from high-salinity sections would mix back into low-salinity areas, rendering this solution ineffective in maintaining distinct salinity levels within different sections of the lake.

Section Title: 6.文章修订

The passage presents three potential solutions to address the increasing salinity of the Salton Sea in California, while the lecture casts doubt on their effectiveness by providing specific counterarguments.

Firstly, the reading suggests that using desalination facilities to remove salt from the lake's water would help restore its health. However, the professor contends that this approach could pose a threat to human health due to the production of toxic chemicals, such as selenium, which could be released into the air during the process.

Additionally, the passage proposes diluting the lake's salt levels with ocean water delivered through pipelines or canals as another solution. The professor challenges this idea by pointing out that it may not be feasible due to financial constraints faced by local governments and high construction costs associated with building pipelines or canals over long distances.

Lastly, the reading posits that constructing walls to divide the lake into several sections and directing freshwater into its main section would help control salinity levels. However, the professor disputes this claim by highlighting that such a solution is unreliable due to geological factors. Specifically, earthquakes in the region could easily destroy these walls, rendering them ineffective in maintaining separate sections with varying salinity levels. (206 words)

3. Grammar

The reading and the lecture are both about solutions to reverse the trend of salinity. The author of the reading passage provides three waysways,(This rule identifies whether commas are missing in a sentence.) while the lecturer identifies weaknesses of them all.

To begin with, the author argues that one method is to remove salt of the lake directly. However, the professor rebuts in the lecture that it might cause dangerous chemicals which are probably blown into the air and do harm to people's health.

Secondly, even though the author suggests that we can dilute the salt level by bringing ocean water into the lake, the professor mentions the unaffordable enpenseexpense(misspelling) of pipulinespipelines(misspelling) in result of the one-kilometer distance between the ocean and the sea, which contradicts the possibility for the local government to tale this advice.

Finally, the author posits that, aiming at directing all the freshwater in the area into one main section of the lake i the use of consturctingconstructing(misspelling) walls, dividing the lake into several sections can control the salinity whereas the professor asserts that it is not a long-term solution since there may be geological activities such as earthquake destroying the walls, convincingly displaying that this means does not make sense.

6. Revised Essay

The reading passage and the lecture both discuss potential solutions to address the increasing salinity of the Salton Sea in California. The author of the reading passage proposes three methods to combat this issue, while the lecturer casts doubt on each of these solutions by highlighting their weaknesses.

Firstly, the reading suggests that desalination facilities could be employed to remove salt directly from the lake's water. However, the lecturer contends that this approach might lead to hazardous consequences. The desalination process would leave behind solid materials, including toxic chemicals such as selenium. If these chemicals were dispersed into the air by wind and subsequently inhaled by people, it could pose significant health risks.

In addition, the author proposes diluting the lake's salt levels by introducing ocean water through pipelines or canals. The lecturer challenges this solution by emphasizing the prohibitive costs associated with constructing such infrastructure. Given that the nearest Pacific Ocean shoreline is located 100 kilometers away from the Salton Sea, building pipelines or canals over such a vast distance would be extremely expensive and likely unaffordable for local government resources.

Lastly, dividing the lake into sections using walls is presented as another potential solution in the reading passage. This method aims to control salinity by directing all freshwater from nearby rivers into one main section of the lake while allowing salinity levels to increase in smaller sections. However, the lecturer disputes this approach's effectiveness as a long-term solution due to frequent geological activity in the region, such as earthquakes. These natural events could potentially destroy constructed walls, causing high-salinity water from separated sections to mix back with low-salinity water in the main section.

Overall, although each proposed solution in the reading passage appears promising at first glance, their feasibility is undermined by various concerns raised during the lecture. Consequently, alternative strategies may need to be explored to effectively address and reverse increasing salinity levels within California's Salton Sea. (323 words)

The reading passage claims that The Salton Sea in California is grappling with a significant dilemma: the salinity is progressively increasing due to a rapid evaporation rate. While the reading passage provides three potential solutions to this issue, the listening portion meticulously debunks each of them, and elucidates some viewpoints on each matter.

Firstly, the reading proposes extracting salt directly from the lake’s water using a special desalination facility. However, the professor contradicts this viewpoint, suggesting that this approach is likely to spawn health problems. As the water evaporates in the desalination facilities, solid materials, containing toxic chemicals such as selenium, are left behind. Consequently, these chemicals might be disseminated by the wind, posing a potential health risk to individuals.

Furthermore, The reading contents introducing ocean water to the lake to mitigate the salt level. Nonetheless, the professor challenges this claim, labeling it as quite impractical. He underscores that the government may lack sufficient funds to construct pipelines or canals, and with the nearest shoreline being 100 kilometers away, the undertaking could be financially draining.

Additionally, The written piece argues dividing the lake into multiple sections by constructing walls. Nevertheless, the professor expresses skepticism about the claim, rebuffing this strategy as being merely provisional since the Salton Sea is situated in a locale where geological activities are frequent and intense. Water from the smaller sections may re-mingle with the main section, rendering this solution ineffective shortly.

In conclusion, despite the reading’s attempt to provide plausible solutions for the escalating salinity in the Salton Sea, the professor convincingly disputes each, highlighting potential health threats, financial impracticalities, and the provisional nature of these approaches, thereby rendering them unreliable.

Nonetheless, the professor challenges this claim, labeling it as quite impractical. impractical (reason: high cost and distance from shoreline). He underscores that the government may lack sufficient funds to construct pipelines or canals, and with the nearest shoreline being 100 kilometers away, the undertaking could be financially draining.

Additionally, The the written piece argues for dividing the lake into multiple sections by constructing walls. Nevertheless, the professor expresses skepticism about the claim, this claim (reason: geological activities in region make it provisional), rebuffing this strategy as being merely provisional since the The Salton Sea is situated in a locale where geological activities are frequent and intense. Water from the smaller sections may re-mingle with the main section, section rendering this solution ineffective shortly.

In conclusion, despite the reading’s The reading's attempt to provide plausible solutions for the escalating salinity in the The Salton Sea, the Sea; professor convincingly disputes each, each one of them by highlighting potential health threats, threats posed by desalination facilities' waste products; financial impracticalities, and the impracticalities of constructing pipelines or canals; and provisional nature of dividing lake into sections due to geological activities in that region which render these approaches, thereby rendering them unreliable.approaches unreliable for solving salinity problem in The Salton Sea.

6.文章修订

Both the author and the professor discuss the desalination solutions for the Salton Sea in California, which faces a trend of increasing salinity levels due to weather conditions, leading to potential ecological destruction. The author proposes three options to address this issue: direct removal of salt using heating devices, decreasing the salinity level with water from the ocean, and building walls to separate the lake into different sections. However, the professor refutes all of these suggestions as they are entirely unrealistic.

Firstly, the professor challenges the first option presented in the reading passage, which involves pumping salty water into a special facility and heating it, by highlighting potential contamination issues. She suggests that besides salt, after the evaporation process there will remain toxic solids which may cause health problems. Additionally, these chemical substances could be dispersed into the air by wind and inhaled by people, posing a significant risk to public health.

Secondly, regarding the second solution of piping seawater into the lake to dilute its salt content, the professor argues that it would be too costly for the government to afford such a project. With the nearest coast being 100 kilometers away, transporting seawater to the lake would require constructing either a pipeline or a canal over long distances. Both options would be extremely expensive and beyond what local authorities could reasonably finance.

Lastly, while dividing Salton Sea into separate sections by constructing walls is suggested as another viable option by author; this idea is debunked by professor due to geological factors. According to her argumentation; since Salton Sea is located in an area with frequent and intense geological activity such as earthquakes; constructed walls would not withstand these forces for long periods of time. Consequently; even if initially effective; such walls would eventually collapse during major seismic events causing high-salinity water from separated sections mixing back with low-salinity water from main section rendering this solution impractical.

By examining each solution presented in the reading passage and considering the counterarguments from the lecture, it becomes evident that the professor disagrees with the author's ideas for desalination, concluding that none of these solutions are practical or realistic. (358 words)

Section Title: 6.文章修订

The reading passage and the lecture both discuss potential solutions to prevent the increasing salinity of the Salton Sea in California. The reading passage presents three proposals: using desalination facilities, diluting the lake with ocean water, and constructing walls to separate sections of the sea. However, the professor systematically refutes each of these points in the lecture.

Firstly, contrary to the writer's idea that desalination facilities could help slow down the trend of increasing salinity, the professor states that this approach would yield additional problems. While water from the sea evaporates in desalination facilities, toxic solid materials are left behind. These chemicals pose a health risk when people breathe them in.

Furthermore, the professor discredits the reading's assertion that diluting Salton Sea water with ocean water through pipelines and canals is a viable solution. The professor explains that local governments likely lack sufficient resources to construct such infrastructure due to its high cost and long distances involved.

Lastly, while the author suggests that constructing walls to divide sections of the lake could be helpful, the speaker highlights an issue with this approach. The region experiences frequent geological activity, such as earthquakes. Inevitably, these events would cause wall collapse and lead to mixing between high-salinity sections and low-salinity main sections.

A clear divide exists between both perspectives regarding approaches to prevent further salinization of Salton Sea. (228 words)

The lecture highlights the urgency of reducing the salinity in the lake water and presents three potential solutions. However, it casts doubt on the effectiveness of these solutions and offers alternative explanations.

Firstly, the reading passage suggests that specialized desalination facilities could effectively remove salt from the lake's water. In contrast, the lecture argues that this process may also extract toxic chemicals, posing significant health risks to humans if they are exposed to these substances.

Secondly, the passage proposes diluting the lake water with ocean water as a practical solution since ocean water has a lower salinity level. However, the lecture counters this by pointing out that constructing pipelines or canals to transport water over long distances would be prohibitively expensive for local governments.

Thirdly, the reading text posits that constructing walls to divide the lake into sections with varying salinity levels could be an effective approach. Nevertheless, the lecture disputes this idea by citing potential damage from earthquakes as a significant concern. Given that the lake is situated in an area prone to earthquakes, any such construction could collapse due to unforeseen natural disasters, causing water from different sections to mix once again.

According to the current situation of inland lakes with increasing salty levels, the author of the writer promotes three possible options, but the lecture disputes the claims made in the reading. Firstly, the writers mention that the salt in the lack can be removed with desalination technology. Turning the salysale(misspelling) into the steam and the salt-free water return to the lack. In the listening, however, the lecturer argues that this will cause serious outcomes. For example, the salt material in the lack may contain some unknown chemicals. When the desalination facilities are used, these chemicals will also be evaporated with the salt. If people around the facilities breathe in poisonous gas, it will be very dangerous. Secondly, the reading passage contends that we can move the water in the ocean into the lack. On the contrary, the lecture disagrees with the notions, (Two consecutive spaces)Because they will cost a lot of money and manpower resources. For these requirements, for one thing, these are very expensive, there are some doubts about if it is necessary to do that. For another thing, the government cannot afford these extra expenses. Lastly, the author points out that we can divide the lack into some parts so that we can only control the main part. Yet the lecturer finds this point indefensible because it is unlikely to be conducted in the long run, Because there is frequent happening geologicalin geological(This rule identifies whether the preposition 'in' is missing in a sentence.) disaster, like an earthquake. For example, after the earthquake occurs, the work that is done before is useless, all will return to the beginning.

6. Revised Essay

The reading passage presents three potential solutions to address the increasing salinity of the Salton Sea in California, while the lecture casts doubt on their feasibility and effectiveness.

Firstly, the reading suggests using desalination facilities to remove salt from the lake's water. However, the lecturer counters this idea by highlighting the potential health risks associated with this method. The solid materials left behind after desalination would not only consist of salt but also other chemicals, some of which could be toxic, such as selenium. If these chemicals were to become airborne and inhaled by people nearby, it could pose a significant danger to their health.

Secondly, the passage proposes diluting the lake's salinity by bringing ocean water into it through pipelines or canals. The lecturer disputes this solution due to its high cost and resource requirements. Constructing pipelines or canals over long distances would be expensive, and there are doubts about whether such an investment is necessary or feasible for local governments.

Lastly, the author recommends dividing the lake into sections with walls to control salinity levels in specific areas. The lecturer finds this suggestion implausible because it would not be sustainable in the long run due to frequent geological activity in the region, such as earthquakes. This activity could potentially destroy these walls and render previous efforts useless as high-salinity water mixes back with low-salinity water from other sections.

Overall, while each proposed solution in the reading passage seems promising at first glance, the lecture highlights significant concerns that cast doubt on their practicality and effectiveness in addressing Salton Sea's increasing salinity problem. (267 words)

For example, the salt material in the lack may contain some unknown chemicals. When the desalination facilities are used, these chemicals will also be evaporated with the salt. If people around the facilities breathe in poisonous gas, it will be very dangerous. (However, the lecturer counters this idea by highlighting potential health risks associated with this method. The solid materials left behind after desalination would not only consist of salt but also other chemicals, some of which could be toxic, such as selenium. If these chemicals were to become airborne and inhaled by people nearby, it could pose a significant danger to their health.)

Secondly, the reading passage contends that we can move the water in the ocean into the lack. On the contrary, the lecture disagrees with the notions, Because notions because they will cost a lot of money and manpower resources. For these requirements, requirements for one thing, thing these are very expensive, expensive there are some doubts about if it is necessary to do that. For that for another thing, the thing government cannot afford these extra expenses. (Secondly, passage proposes diluting lake's salinity by bringing ocean water into it through pipelines or canals. The lecturer disputes this solution due to its high cost and resource requirements. Constructing pipelines or canals over long distances would be expensive and there are doubts about whether such an investment is necessary or feasible for local governments.)

Lastly, the author points out that we can divide the lack into some parts so that we can only control the main part. Yet the lecturer finds this point indefensible because it is unlikely to be conducted in the long run, Because run because there is frequent happening geological disaster, disaster like an earthquake. For example, after the earthquake occurs, the work that is done before is useless, all will return to the beginning.beginning. (Lastly, author recommends dividing lake into sections with walls to control salinity levels in specific areas. The lecturer finds this suggestion implausible because it would not be sustainable in long run due to frequent geological activity in region such as earthquakes. This activity could potentially destroy these walls and render previous efforts useless as high-salinity water mixes back with low-salinity water from other sections.)

Overall, while each proposed solution in reading passage seems promising at first glance, lecture highlights significant concerns that cast doubt on their practicality and effectiveness in addressing Salton Sea's increasing salinity problem.
