In my perspective, scientific discovery from the last two hundred years paves a solid foundation for our life today. For example, vaccine is the monumental invention that correlated with everyone's life. Especially when the famine period, people were readily infected by various unknown disease due to their unhealthy body and limited knowledge of hygiene. The population was dramatically decreased by the wide spread of disease. Fortunately, scientists invented vaccinea vaccine(This rule identifies whether the article 'a' is missing in a sentence.) that could help our body recognize the potential virus and practice the self-protection function of the immune system.

Vaccines have played a crucial role in combating diseases, particularly during times of famine when people were more susceptible to infections due to malnutrition and limited knowledge of hygiene. The widespread prevalence of diseases led to a decline in population; however, the invention of vaccines enabled our immune systems to recognize potential viruses and defend against them effectively.

In response to the professor's question, while Paul's argument regarding space satellites and Claire's perspective on medical progress hold some merit, I believe that the development of taller and more spacious buildings has had a more significant impact. The construction of such buildings in urban areas can substantially alleviate housing shortages while simultaneously enhancing city infrastructure.

For instance, in the past, people were accustomed to living in houses with considerable distances between them. However, with the advent of technology and large companies, urban areas have become increasingly crowded, exacerbating housing shortages. Fortunately, the invention of taller and more spacious buildings has allowed for greater accommodation within a single area, promoting economic development within cities. Additionally, providing ample living spaces for city dwellers can contribute positively to their mental well-being and physical health. Thus, I contend that the construction of taller buildings in urban areas has made a significant change to human life.

For example, in earlier times, individuals were accustomed to residing in homes with considerable distances between them. However, due to technological advancements and the emergence of large corporations, urban spaces have become increasingly congested, exacerbating housing scarcities. Fortunately, the innovation of taller and more capacious buildings has facilitated greater accommodation within a confined area, fostering economic growth within cities. Moreover, providing ample living quarters for urban residents can positively influence their mental well-being and physical health. Consequently, I argue that the development of taller structures in metropolitan areas has significantly altered human life. (152 words)
