In this discourse, embarking on discussing the topic of recent discovery, Doctor Achebe has invited the students to come up with perspectives on what invention or discovery from the last two hundred years is most salutary. While I appreciate the points mentioned by both Paul and Claire, I firmly believe that the mobile phone symbolizes the most notable in recent years. We all know that contemporary resources and applications have a vast amount and are usually saved in the computer, which is heavy and hard to carry. Remember that individuals are more likely to communicate and search for information conveniently, so the invention of the mobile phone has provided several applications encompassing social media and entertainment services. Some people may feel that computer has more resources in accuracy, yet computer will not concern the problem with daily utilization.

In response to Dr. Achebe's inquiry regarding the most significant scientific discovery or technological invention from the last two hundred years, I would like to propose the development of antibiotics as a crucial advancement. This medical breakthrough has profoundly impacted human health and well-being, reducing mortality rates caused by bacterial infections.

Firstly, antibiotics have revolutionized the treatment of various infectious diseases, enabling doctors to combat previously untreatable conditions effectively. Consequently, this has led to a substantial increase in life expectancy worldwide. Furthermore, antibiotics have played a pivotal role in making surgical procedures safer by preventing postoperative infections.

However, it is essential to acknowledge the challenges associated with antibiotic resistance due to their overuse and misuse. As we continue to rely on these life-saving drugs, it is imperative that we invest in research and development of new antibiotics and alternative treatments to ensure our ability to combat bacterial infections in the future.

While both Paul's suggestion of space satellites and Claire's focus on nutrition are noteworthy contributions, I believe that the discovery of antibiotics has had a more immediate and widespread impact on human lives across the globe. (188 words)

However, there is room for improvement in elaborating on the viewpoint and connecting it more directly to the professor's question about economics. To improve, consider discussing how airplanes have impacted global trade, economic growth, or job creation.

Example 1: "Airplanes have revolutionized global trade by enabling faster transportation of goods across continents, leading to increased economic growth and job creation in various industries."

Example 2: "The aviation industry itself has created numerous jobs in manufacturing, maintenance, and operations, contributing significantly to the global economy."

Suggestion 2: Use transition words or phrases to guide readers through your essay smoothly.

Example 2: "Furthermore, airplanes have facilitated access to foreign products for consumers around the world."

5. Grammar

In my opinion, airplanes are the most crucial and indispensable inventions in the last twenty decades. This is because they save a lot of transportation time and money. For instance, to depart from China to the United States, in the past, the only way was to take ships, usually only the wealth and make it, and this journey usually took three months. With the advanced airplanes, people from all walks of life can afford cheaper tickets, and the trip from China to the United States only takes 24 hours. In addition, airplanes can make people gain access to foreign items. For example, the bananas planted in Thailand can be transported to England and sold there. This not only brings more profits to farmers in Thailand but also broadens England residents' horizons that bananas are delicious.

Undoubtedly, the invention of airplanes has had a transformative impact on our lives over the past two centuries. Air travel has revolutionized transportation by significantly reducing time and cost barriers, making it accessible to people from all socioeconomic backgrounds. For example, a journey from China to the United States that once took three months by ship can now be completed in just 24 hours via air travel. This accessibility has not only facilitated global mobility but also promoted cultural exchange and economic growth. The ability to transport goods, such as Thai bananas being sold in England, benefits both producers and consumers alike.

Over the past 200 years, numerous scientific discoveries and technological inventions have significantly impacted our lives. Among these, I believe that vaccines and antibiotics stand out as the most crucial advancements. These medical breakthroughs, pioneered by researchers like Pasteur, have revolutionized healthcare and saved countless lives.

In the past, life expectancy was much lower due to rampant diseases and poor living conditions. The development of vaccines has enabled us to eradicate deadly illnesses such as smallpox and polio, while also providing critical insights into the workings of our immune system. This knowledge has allowed us to better understand how our bodies react to pathogens and develop defenses against them.

Similarly, antibiotics have transformed medicine by effectively treating bacterial infections that were once fatal. The discovery of penicillin by Alexander Fleming marked a turning point in human history, as it opened the door for the development of various other antibiotics that continue to save lives today.

The impact of these discoveries extends beyond individual health; they have also contributed significantly to global economic growth. With healthier populations able to work more efficiently and contribute to society, we have witnessed unprecedented progress in various fields. Thus, it is evident that vaccines and antibiotics are among the most important scientific discoveries of the last two centuries due to their profound influence on human health and overall well-being.
