Whether pterosaurs are able to fly is the focus of both the writer and the professor. In the writing, three explanations, including less powerful, too heavy, and lack muscleof muscle(This rule identifies whether the preposition 'of' is missing in a sentence.), have been elaborated to explain why pterosaurs can not fly. The professor, however, claims that all such assumptions are incorrect.

As opposed to the writer's view that pterosaurs are cold-blooded with a slow metabolism, which can not make enough energy to support their flight, the professor states that fossils show that they are capable to produce energy. She advances the theory by saying that fossils show that pterosaurs have dense and covered fur, which are always used by warm-blooded animals to maintain their body temperature. Therefore, pterosaurs can produce enough energy to help them fly.

The professor continues to discredit the writing's assertion that pterosaurs are too heavy to fly, by examining the fact that some features show that pterosaurs actually are light. In detail, she points out that pterosaurs' bones are hollow, allowing them to have a low-body weight. Consequently, they can be kept airboneairborne(misspelling) and flap their wings.

It is the professor's third argument that pterosaurs are able to take off from the ground, which contradicts the view of the writer that due to lack legsof legs(This rule identifies whether the preposition 'of' is missing in a sentence.) and small muscles, it is difficult for pterosaurs to fly. To explore deeper, the professor contends that birds are different from pterosaurs, since birds only use their hind legs to help them push off from the ground. However, pterosaurs can use their all four legs to help them take off, so there is no trouble for them to fly into the air.

An apparent divide exists between the writer and the professor on whether pterosaurs can fly.

Section Title: 6.文章修订

The ability of pterosaurs to fly is the central topic of discussion for both the author and the lecturer. The author presents three arguments against pterosaur flight, including insufficient energy production, excessive weight, and inadequate muscle strength. However, the lecturer refutes each of these points, providing evidence to support the notion that pterosaurs were indeed capable of flight.

Contrary to the author's claim that pterosaurs were cold-blooded with a slow metabolism, unable to generate sufficient energy for flight, the lecturer asserts that fossil evidence indicates they could produce ample energy. She explains that these fossils reveal a dense fur-like covering on pterosaurs, which is characteristic of warm-blooded animals that need to maintain a constant body temperature. Consequently, it is likely that pterosaurs had enough energy for powered flight.

Furthermore, the lecturer challenges the author's assertion that pterosaurs were too heavy for flight by highlighting anatomical features that suggest they were actually quite lightweight. Specifically, she notes that their bones were hollow rather than solid, resulting in a lower overall body weight. This reduced weight would have allowed them to remain airborne and flap their wings effectively.

Lastly, the lecturer disputes the author's argument that pterosaurs lacked adequate leg strength and muscle size for taking off from the ground. She emphasizes that unlike birds—which rely solely on their hind legs for launching—pterosaurs utilized all four limbs when taking off. Drawing parallels with modern-day bats who also use all four limbs during takeoff, she posits that even large pterosaurs would have been able to run or jump with sufficient force to become airborne.

In conclusion, there is a clear disagreement between the author and lecturer regarding whether or not pterosaurs could fly. (283 words)

In contrast, the lecture explains that recent fossil discoveries show pterosaurs had a dense, fur-like covering, which is typical of warm-blooded animals needing to maintain a high body temperature.

For example, thePterosaur bones of Pterosaurs arewere hollow, which keepskept the weight of Pterosaurs low enough to support their powered flight. Thirdly, the reading materials points out that Pterosaurs cannotsuggest that Pterosaurs could not fly because they don'tdid not have the strong legs just like other animals with powered flight to help them launch off the ground.

Therefore, with four limbs, Pterosaurs cancould run fast and high enough to take off.

Section Title: 6.文章修订

The reading passage and lecture both discuss the ability of Pterosaurs to achieve powered flight by flapping their wings. While the author argues that Pterosaurs were incapable of powered flight, the speaker presents opposing evidence to support their ability to fly.

Firstly, the author contends that Pterosaurs, being ancient reptiles, likely had a slow metabolism similar to modern reptiles, which would not provide sufficient energy for powered flight. In contrast, the lecturer refutes this claim by pointing out that Pterosaur fossils exhibit a dense, hair-like covering akin to fur - a characteristic of warm-blooded animals. Consequently, if Pterosaurs were warm-blooded, they could generate enough energy for flight.

Secondly, the writer asserts that the heavy weight of Pterosaurs would prevent them from staying aloft in the air for any significant duration. However, the speaker counters this argument by highlighting that Pterosaurs possessed lightweight features despite their large size. For instance, their bones were hollow rather than solid, reducing their overall weight and enabling them to maintain powered flight.

Lastly, the reading passage suggests that Pterosaurs could not achieve powered flight due to their lack of strong leg muscles needed for launching off the ground like other flying animals. In opposition to this view, the lecturer explains that unlike birds which use only two limbs for takeoff, Pterosaurs utilized all four limbs to push off from the ground - a method employed by modern flying animals such as bats. Therefore, with four limbs at their disposal, Pterosaurs could run fast and jump high enough for successful takeoff and sustained flight. (261 words)

First, according to the author, just like Firstly, the author contends that Pterosaurs, being ancient reptiles, likely had a slow metabolism similar to modern reptiles, Pterosaurs, as a kind of ancient reptile, are more likely to have slow metabolism, which can would not provide enough sufficient energy to support powered flight. However, for powered flight. In contrast, the lecturer rejects it refutes this claim by arguing that the fossil of Pterosaurs has a layer of dense and hair pointing out that Pterosaur fossils exhibit a dense, hair-like covering fur, which is actually a typical feature of warm blooded animals. Therefore, akin to fur - a characteristic of warm-blooded animals (clarified and rephrased for better flow). Consequently, if Pterosaurs are blooded animals, were warm-blooded, they can could generate enough energy to fly. for flight.

Secondly, the writer states asserts that the heavy weight of Pterosaurs would prevent them from staying aloft in the air for any significant duration. However, the speaker counters this argument by highlighting that Pterosaurs possessed lightweight features despite their large size (rephrased for clarity). For instance, their bones were hollow rather than solid, reducing their overall weight and enabling them to maintain powered flight.

Lastly, the reading passage suggests that Pterosaurs could not stay aloft in the air for any seconds because of its heavy weight. On the contrary, the speaker challenges it and mentions that Pterosaurs actually have the features of light weight despite its large soze. For example, the bones of Pterosaurs are hollow, which keeps the weight of Pterosaurs low enough to support their powered flight. ¶ Thirdly, the reading materials points out that Pterosaurs cannot fly because they don’t have the achieve powered flight due to their lack of strong legs just leg muscles needed for launching off the ground like other animals with powered flight to help them launch off the ground. ¶ flying animals. In contrast, the listening directly refutes it by claiming that the taking off the ground with opposition to this view, the lecturer explains that unlike birds which use only two limbs are the way how bird do to launch. Actually, Pterosaurs launch in a different way from birds by using for takeoff, Pterosaurs utilized all the four limbs to push off the ground, just like from the ground - a method employed by modern flying animals do. such as bats (rephrased and clarified). Therefore, with four limbs, Pterosaurs can limbs at their disposal (added "at their disposal" for emphasis), Pterosaurs could run fast and jump high enough to take off.for successful takeoff and sustained flight.

The reading passage presents that pterosaurs, a kind of large, winged reptiles, are unable to do powered flight. The professor, however, points out that the pterosaurs are actually capable of doing powered flight. First, according to the reading, pterosaurs are cold-blooded, which means that they can not create enough energy needed to fly like those warm-blooded animals. But, the professor says that from recent research of pterosaurs fossils, scientists found that pterosaurs wings were covered with dense hair or fur. This hair like covering is a typical feature for those warm-blooded animals that fly. The covering of hair or fur can help these warm-blooded animals generate enough energy for powered flight. So with the same feature as warm-blooded animals, and with high moving speed, pterosaurs could also create enough energy for powered flight. Second, the reading passage contends that pterosaurs' powered flight were limited by their large body and heavy weight. However, the professor argues that pterosaurs' special body structure made their body unsusallyusually(misspelling) light. By researching from their fossils, researchers found that their bones were hollow instead of solid, which made their weight low enough to take off from the ground despite their large outline. Third, the reading passage indicates that unlike birds which can take off by running or jumping to gain speed to fly, pterosaurs' back legs couldn't afford running fast or jumping high. WherasWhereas(misspelling), the professor proposes that pterosaurs were unable to launch themselves with their back legs indeed, but they actually used their four limbs to stand on the ground. So if they used their four limbs to run or jump, there would be no problem for them to run fast or jump high to get enough speed for powered flight.

6.文章修订

The reading passage posits that pterosaurs, a type of large, winged reptiles, were incapable of powered flight. However, the professor in the lecture contends that pterosaurs were indeed capable of powered flight.

Firstly, the reading asserts that pterosaurs were cold-blooded and thus could not generate sufficient energy required for powered flight like warm-blooded animals. Contrarily, the professor mentions that recent research on pterosaur fossils has revealed that their wings were covered with dense hair or fur. This hair-like covering is a typical feature of warm-blooded animals that need to maintain a high body temperature in cold conditions. Consequently, if pterosaurs had a similar hair-like covering as warm-blooded animals, their metabolism would be faster than cold-blooded animals, allowing them to generate enough energy for powered flight.

Secondly, the reading passage contends that the large size and heavy weight of pterosaurs limited their ability to achieve powered flight. On the other hand, the professor argues that the unique body structure of pterosaurs made them lighter than expected. Researchers discovered that pterosaurs had hollow bones instead of solid ones, which significantly reduced their weight and allowed them to achieve powered flight despite their large size.

Lastly, the reading passage indicates that unlike birds which can take off by running or jumping to gain speed for flying, pterosaurs' back legs could not support running fast or jumping high. However, the professor points out that while it is true that pterosaurs could not launch themselves using only their back legs, they actually used all four limbs to stand on the ground. By employing all four limbs to run or jump, they would have had no problem achieving sufficient speed for powered flight. This method is similar to how modern flying animals like bats use all four limbs to push off from the ground.

In light of these opposing arguments presented by the professor, it becomes evident that pterosaurs were indeed capable of powered flight, contrary to the claims made in the reading passage. (329 words)

Section Title: 6.文章修订

The reading and listening materials discuss the ability of Pterosaurs to achieve powered flight. The reading passage presents three arguments against this ability, focusing on metabolism, weight, and leg muscles. However, the lecture opposes each of these points by providing alternative explanations.

Firstly, the reading passage argues that Pterosaurs' cold-blooded nature would result in a slow metabolism rate, preventing them from generating enough energy for powered flight. In contrast, the lecture contends that recent fossil discoveries show Pterosaurs had a dense fur-like covering, which is typical of warm-blooded animals. This suggests that their metabolism could have been faster than previously thought, providing sufficient energy for powered flight.

Secondly, the reading claims that Pterosaurs were too heavy for powered flight due to their large size and weight. The lecture disputes this point by explaining that Pterosaurs had evolved specific anatomical features to adapt to their size. For example, their bones were hollow instead of solid, reducing their overall weight and allowing them to generate enough lift for powered flight.

Lastly, the reading asserts that Pterosaurs would not have been able to take off from the ground due to weak back leg muscles. The lecture refutes this argument by highlighting a key difference between Pterosaurs and birds: while birds use only their hind limbs for takeoff, Pterosaurs utilized all four limbs.

Firstly, the reading suggests that Pterosaurs were cold-blooded reptiles, unable to generate sufficient energy for powered flight. However, the lecture counters this argument by stating that recent fossil discoveries indicate that Pterosaurs had a dense, fur-like covering, which is characteristic of warm-blooded animals. This implies that their metabolism was more similar to warm-blooded creatures and could have provided them with enough energy for powered flight.

Secondly, the reading claims that the large size and weight of Pterosaurs would have made it impossible for them to stay airborne through powered flight.

The effectiveness of the arguments made against the powered flight of pterosauspterosaur(misspelling) is debated by both the author and the lecturer. The author suggests three arguments: cold-blooded animals, large weight and weekweak(Detects potentially wrong usage of "week" instead of "weak") leg muscles. However, the lecturer disputes each of these proposals. Contrary to the author's belief that pterosauspterosaur(misspelling) which isare(Detects potentially wrong usage of "is") ancient reptiles are probably cold-blooded animals, the lecturer argues that pterosauspterosaur(misspelling) are warm-blooded animals. He explains that we find pterosauspterosaur(misspelling) have dense hair like covering and fur covering from fossilfossil,(This rule identifies whether commas are missing in a sentence.) which is typical feature of the warm-blooded animals. So pterosauspterosaur(misspelling) have a suitable metabolism to produce a lot of energy and their fur covering can protect energy from losing which can help them hold a high temperature in a cold environment. The lecturer also challenges the author's claim that pterosauspterosaur(misspelling) were probably too heavy to stay aloft for any length of time. He points that the practical weigh of pterosauspterosaur(misspelling) might be a little light. Furthermore, since the bones of pterosauspterosaur(misspelling) are hollow, the weigh of pterosauspterosaur(misspelling) is much smaller than we think and pterosauspterosaur(misspelling) can easily keep airborne with their body in the winds. Lastly, while the author posits that pterosauspterosaur(misspelling)'(Unpaired braces, brackets, quotation marks and similar symbols) back leg muslesmuscles(misspelling) were too small and weak to allow the pterosauspterosaur(misspelling) to run fast enouhenough(misspelling) or jump high enough to launch themselves into the air, the lecturer contends that the pterosauspterosaur(misspelling) had four limbs on land. He further explained that birds have powerful muscles in their legs, but they only have two limbs on land to push off the ground. However, as for pterosauspterosaur(misspelling), they had four limbs to push off the ground which make them have no trouble to jump high enouhenough(misspelling) to launch themselves in to the air. In conclusion, there is a clear disagreement between the author and lecturer regarding whether the arguments have been made against powered flight of pterosauspterosaur(misspelling).

He cites evidence from fossils showing a dense hair-like covering and fur on pterosaurs, which are typical features of warm-blooded animals. Consequently, pterosaurs would have had a metabolism suitable for producing ample energy and maintaining a high body temperature in cold environments.

Furthermore, the lecturer challenges the author's claim that pterosaurs were too heavy to sustain powered flight. He argues that their actual weight might have been lighter than assumed due to their hollow bone structure. This lightweight anatomy would have allowed pterosaurs to stay airborne more easily than initially thought.

Lastly, while the author contends that pterosaurs' weak back leg muscles prevented them from launching into the air effectively, the lecturer counters this by highlighting their four-limbed locomotion on land. Unlike birds, which only use two limbs to push off from the ground, pterosaurs could utilize all four limbs for propulsion. This advantage would have enabled them to jump high enough to initiate powered flight.

In light of these counterarguments presented by the lecturer, it becomes evident that there is a significant disagreement between both parties regarding whether or not pterosaurs were capable of powered flight. (244 words)

The effectiveness of the arguments made against the powered flight of pterosaus pterosaurs is debated by both the author and the lecturer. The author suggests three arguments: cold-blooded animals, large weight and week weight, and weak leg muscles. However, the lecturer disputes each of these proposals.

Contrary to the author's belief that pterosaus pterosaurs, which is are ancient reptiles are reptiles, were probably cold-blooded animals, animals (change "pterosaus" to "pterosaurs" for correct spelling), the lecturer argues that pterosaus are pterosaurs were warm-blooded animals. He explains that we find pterosaus have pterosaurs have a dense hair like hair-like covering and fur covering from fossil fossils (rephrase for clarity), which is a typical feature of the warm-blooded animals. So pterosaus have So, pterosaurs had a suitable metabolism to produce a lot of energy energy, and their fur covering can could protect energy from losing being lost (change "losing" to "being lost" for better phrasing), which can help them hold maintain a high temperature in a cold environment.

The lecturer also challenges the author's claim that pterosaus pterosaurs were probably too heavy to stay aloft for any length of time. He points out that the practical weigh of pterosaus weight of pterosaurs might be a little light. lighter (change "weigh" to "weight" for correct word usage). Furthermore, since the bones of pterosaus pterosaurs are hollow, the weigh of pterosaus their weight is much smaller than we think and pterosaus think, and they can easily keep airborne with their body in the winds. winds (rephrase for clarity).

Lastly, while the author posits that pterosaus' pterosaurs' back leg musles muscles were too small and weak to allow the pterosaus them to run fast enouh enough or jump high enough to launch themselves into the air, the lecturer contends that the pterosaus they had four limbs on land. land (clarify point).

3. Grammar

Whether pterosaurs were capable of powered flight is the focus of both the author and the lecturer. Three obstacles, including being cold-blooded, having heavy weight and cannot take off from the ground have been elaborated in the writing. The lecturer, however, thinks such arguments are incorrect.

As opposed to the author’s idea that pterosaurs were unable to generate enough energy for powered flight, the lecturer points out their metabolism could supply them with enough energy. He advances that some evidence found that there were dense and hair-like covering on pterosaurs, indicators of warm-blooded animals, which means they need to maintain their body temperature when external conditions changed and, and(comma between independent clauses) thus they have fast metabolism.

The lecturer continues to discredit the author's assertion that pterosaurs were too heavy to conduct powered flight, by examining the fact that they weighted light by possessing special anatomical features. He explores deeper and points out that pterosaurs' bones, instead of being solid, were hollow; so, despite large body frames, they were not heavy and were able to flap wings and stay aloft.

It is the lecturer's last argument that pterosaurs could take off from the ground, which contradicts the author's view that they could not launch themselves into the air. He contends that differences ofin(This rule identifies wrong preposition usage.) the number of limbs between birds and Pterosaurs are the key point. Pterosaurs' four strong limbs guaranteed to provide adequate speed and height to lift themselves into the air.

6.Revised Essay

The debate over whether pterosaurs were capable of powered flight is addressed by both the author and the lecturer. The reading passage presents three obstacles to powered flight: being cold-blooded, having a heavy weight, and an inability to take off from the ground. However, the lecturer refutes these arguments with opposing evidence.

Firstly, contrary to the author's assertion that pterosaurs' cold-blooded nature would prevent them from generating sufficient energy for powered flight, the lecturer contends that their metabolism could have supplied them with adequate energy. He cites recent fossil discoveries showing that pterosaurs had a dense, hairlike covering, which is typical of warm-blooded animals. This fur-like covering suggests that they needed to maintain their body temperature when external conditions changed, indicating a faster metabolism than previously assumed.

Secondly, in contrast to the author's claim that large pterosaurs were too heavy for powered flight, the lecturer highlights their unique anatomical features that made them lighter than expected. He explains that pterosaurs' bones were hollow rather than solid, which significantly reduced their weight despite their large body frames. Consequently, this lightweight structure would have allowed them to flap their wings and remain airborne.

Lastly, the lecturer disputes the author's view that pterosaurs could not launch themselves into the air due to weak back leg muscles. He emphasizes the crucial difference between birds and pterosaurs in terms of limb usage: while birds rely solely on their hind limbs for walking and launching into flight, pterosaurs utilized all four limbs on the ground. Drawing parallels with modern bats, he argues that even large pterosaurs could have used all four limbs to generate enough speed and height for takeoff.

By addressing each point raised in the reading passage with counterarguments supported by recent research findings and comparisons to modern animals, the lecturer effectively challenges the notion that pterosaurs were incapable of powered flight. (310 words)

The passage introduces the topic of the impossibility of (Two consecutive spaces)pterosaurs are able to support powered flight. The lecture counters this by claiming that pterosaurs are capable of powered flight and refutes each of the reasons made in the reading.

Firstly, the reading passage states that the feature of slow metabolism of cold-blooded animals, including pterosaurs, are unable to produce enough energy for powered flight. The lecturer, however, believes that there are flaws in the author's positiionposition(misspelling). He contends that according to the recent discovered fossils, pterosaurs are covered by dense and hair-like feather to maintain high body tempreturetemperature(misspelling), indicating them a kind of warm-blooded animal. In this way, pterosaurs with high-metabolism can generate the energy needed for powered flight.

Secondly, the author considers that powered flight is limited to weight and pterosaurs are too heavy to flap wings fast enough to fly. The instructor, on the other hand, refutes this statement and argues that pterosaurs are actually light even for their sizes. He goes on to take an example that pterosaurs'spterosaur's(wrong genitive (e.g., 'employees's' instead of 'employee's')) bones are hallowhallowed(Agreement: 'been' or 'was' + past tense), instead of solid, which provides pterosaurs with lower weight and support powered flight by flapping wings.

Finally, the reading implies that back leg muscles of pterosaurs are too weak to run fast and jump high for launching them into the air. Casting doubt on the claim, the professor points out that pterosaurs walking in four legs, push themselves off the ground also with four legs, rather than two back legs similar as birds, offering them chances to run fast enough and jump high enough to launch themselves into the air.

Whether large pterosaurs were capable of powered flight or not is the focus of both the writer and the professor. In the writing, three reasons, including inadequate energy, large size and weak leg muscles, have been elaborated to support that the pterosaurs could only glide. The professor, however, claims that all the arguments above are unconvincing.

As opposed to the writer's idea that pterosaurs may be the cool-blooded animals that are not able to generate sufficient energy for fly, the professor states that pterosaurs can provide such energy for fly since it has the possibility that pterosaurs are warm-blooded animals due to fossils.

Section Title: 6.文章修订

The debate over whether large pterosaurs were capable of powered flight is addressed by both the author and the lecturer. The author presents three arguments against powered flight, including insufficient energy production, excessive size, and weak leg muscles. However, the lecturer refutes each of these points.

Contrary to the author's claim that pterosaurs might have been cold-blooded animals unable to generate enough energy for flight, the lecturer argues that they could have been warm-blooded due to evidence from fossils. She explains that dense hair-like coverings found on pterosaur fossils suggest they were warm-blooded since such coverings help maintain a high body temperature in cold environments.

Next, the lecturer challenges the author's assertion that pterosaurs were too large to flap their wings quickly enough for powered flight. She highlights anatomical features that allowed them to be lighter than their size would suggest, such as hollow bones instead of solid ones. This reduced weight would have enabled them to flap their wings effectively for flight.

Lastly, the lecturer disputes the author's argument regarding differences in takeoff methods between pterosaurs and birds. She points out that while birds rely on powerful back leg muscles and two limbs for takeoff, other flying animals like bats use all four limbs to push off from the ground. This suggests that even large pterosaurs could have taken off using a similar method.

In conclusion, there is a clear disagreement between the author and lecturer regarding whether or not large pterosaurs were capable of powered flight. The lecturer effectively counters each of the author's arguments with alternative explanations supported by recent research findings. (268 words)

TPO 47 ¶ Whether The debate over whether large pterosaurs were capable of powered flight or not is the focus of addressed by both the writer and the professor. In the writing, author and the lecturer. The author presents three reasons, arguments against powered flight, including inadequate energy, large size insufficient energy production (changed "inadequate energy" to "insufficient energy production" for clarity), excessive size, and weak leg muscles, muscles. However, the lecturer refutes each of these points.

Contrary to the author's claim that pterosaurs might have been elaborated to support that the pterosaurs cold-blooded animals unable to generate enough energy for flight (rephrased for clarity), the lecturer argues that they could only glide. The professor, however, claims that all the arguments above are unconvincing. ¶ As opposed to the writer's idea that pterosaurs may be the cool-blooded animals that are not able to generate sufficient energy for fly, the professor states that pterosaurs can provide such energy for fly since it has the possibility that pterosaurs are have been warm-blooded animals due to evidence from fossils. She advances the theory by saying explains that dense coverings, working like fur, have been hair-like coverings found in pterosaurs' fossils, which indicates that pterosaurs are on pterosaur fossils suggest they were warm-blooded because the covering can hold since such coverings help maintain a high body temperature when in a cold environment. environments (clarified explanation).

The professor continues to discredit the writer's Next, the lecturer challenges the author's assertion that pterosaurs are were too large to flap their wings fast enough, by examining the fact that they have some quickly enough for powered flight (rephrased for clarity). She highlights anatomical features to enable that allowed them become light for to be lighter than their size despite of large body. In detail, she points out that pterosaurs have would suggest, such as hollow bones instead of solid ones, making ones (clarified example). This reduced weight would have enabled them to flap their wings effectively for flight (added connection between weight low enough for flapping wings to fly. and flight).

It is the writer's third Lastly, the lecturer disputes the author's argument that regarding differences exist in takeoff methods between the methods used by pterosaurs and birds for taking off, which contradicts to the view of the writer that pterosaurs need (rephrased for clarity). She points out that while birds rely on powerful and big back leg muscles similar to birds' back legs in order to run fast or jump high. To explore deeper, she contends that birds only use their and two limbs to take off so strong muscles are necessary; on the contrary, some for takeoff, other animals, including bats, can utilize flying animals like bats use all four limbs to push off the ground. from the ground (clarified comparison). This suggests that even large pterosaurs could have taken off using a similar method (connected example to main point).

An apparent divide exists In conclusion, there is a clear disagreement between the writer and the professor on the possibility of pterosaurs have ability to make powerful flight.author and lecturer regarding whether or not large pterosaurs were capable of powered flight. The lecturer effectively counters each of the author's arguments with alternative explanations supported by recent research findings (summarized main points and emphasized the lecturer's position).
