Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 31 to 40.

[I] Social media has become a dominant force in modern communication, offering a range of benefits and challenges. [II] It has revolutionized the way people interact, share information, and even form relationships. [III] While these platforms offer opportunities for connection and expression, they also have their drawbacks. [IV] For instance, excessive use of social media has been linked to a range of negative effects, including mental health issues, social isolation, and decreased productivity. [V] However, when used responsibly, social media can also offer a variety of positive outcomes, such as the ability to stay connected with loved ones, network professionally, and access valuable information and resources.

One of the major benefits of social media is its ability to keep people connected. For example, individuals who live far apart can maintain close relationships through regular communication on these platforms. Social media also facilitates professional networking, allowing users to connect with potential employers or clients, and enabling companies to promote their products and services to a global audience. Additionally, platforms like Facebook, Twitter, and Instagram provide a space for people to share ideas, opinions, and creative work, fostering a sense of community and collaboration.

Despite these advantages, there are serious concerns about the negative impact of social media, particularly on mental health. Studies have shown that excessive social media use can contribute to feelings of anxiety, depression, and loneliness. This is often attributed to the unrealistic portrayals of life that are commonly shared on these platforms, leading to comparisons that can make individuals feel inadequate or left out. Furthermore, constant exposure to negative news or online bullying can exacerbate these feelings and contribute to long-term psychological stress.

Another issue with social media is its potential to distract people from their daily responsibilities. With notifications constantly popping up and endless streams of content to scroll through, individuals may find it difficult to focus on tasks such as work, school, or personal obligations. This can result in decreased productivity and a lack of attention to important matters.

Ultimately, the impact of social media depends on how it is used. If individuals are mindful of their usage patterns and take steps to limit their time on these platforms, they can enjoy the benefits of staying connected and informed without the negative consequences. Parents, educators, and mental health professionals can also play a role in helping young people develop healthy habits and manage their social media use effectively.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 33 to 40.

Air pollution is a significant environmental issue that affects millions of people worldwide. It results from various sources, including industrial emissions, vehicle exhaust, and the burning of fossil fuels. [I] Among the most harmful pollutants are fine particulate matter (PM2.5), carbon monoxide, sulfur dioxide, and nitrogen oxides. These pollutants not only degrade air quality but also have serious health consequences, such as respiratory diseases, cardiovascular problems, and even premature death. [II]

In major cities, traffic congestion plays a critical role in worsening air pollution. The high concentration of vehicles, particularly those running on diesel fuel, releases large amounts of pollutants into the atmosphere. [III] Additionally, industrial activities in urban areas contribute to the problem by emitting harmful gases and chemicals. [IV]

Governments and environmental organizations have been implementing various measures to combat air pollution. These include promoting the use of renewable energy, encouraging public transportation, and imposing stricter emission regulations on industries. Moreover, advancements in technology have led to the development of electric vehicles and air purification systems, which help reduce pollution levels. However, despite these efforts, achieving clean air remains a global challenge that requires cooperation from all sectors of society.
