Sample Answer for Task 1

The pie charts illustrate the changes in the proportions of energy generated from five sources—hydropower, oil, nuclear power, coal, and natural gas—in a country between 1983 and 2003.

Overall, oil remained the dominant energy source in both years despite a slight decline, while nuclear power and natural gas saw increased usage by 2003. In 1983, oil accounted for 42% of energy production, followed by coal at 23%. Over the 20-year period, oil’s share decreased by 4% to 38%, and coal’s share dropped significantly by 10% to 13%.

In contrast, nuclear power and natural gas increased by 4% and 10%, respectively, collectively surpassing coal’s contribution by 2003. Hydropower, however, remained stable at 4% in both years, making it the least significant source.

Sample Answer for Task 2

Globalization has led to increased business and cultural interactions between countries, sparking debate about its impacts. While some argue that this trend erodes national identities, I believe the benefits of such exchanges outweigh the drawbacks.

Critics of international trade and cultural exchange contend that they harm national identities. In developing countries, foreign investments often prioritize exports, neglecting domestic production and minimally improving local living standards. Culturally, adopting foreign customs can erode local traditions. For example, in the 20th century, parts of Cherokee culture in the US were lost as communities adopted European settlers’ practices to conform.

However, I believe the advantages are substantial. International trade enables access to diverse products at competitive prices, enhancing consumer choice. Culturally, exposure to foreign films, music, and ideas via the internet fosters mutual respect and understanding. For instance, international students gain firsthand cultural insights, building personal connections and broadening perspectives.

In conclusion, while protecting national identity is important, the economic and cultural benefits of global exchanges are significant, and countries can preserve their heritage through conscious efforts.
