Read the following passage about the The Importance of Social Media in Modern Society 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 31 to 40.

In the 21st century, social media has become a crucial element of everyday life[I]. Platforms such as Facebook, Twitter, Instagram, and TikTok link individuals around the world, [IV]. Although some may critique social media for promoting negativity, it is important to acknowledge its numerous positive effects on society[III]. This essay will delve into the importance of social media, its influence on shaping public perception, and the challenges it poses.[II]

One of the primary benefits of social media is its ability to foster communication and connection. People can maintain relationships with friends and family, regardless of geographical barriers. This aspect is particularly vital for those who live far away from loved ones. For example, a student studying abroad can easily share their experiences with family through posts, photos, and video calls. Furthermore, social media enables individuals to connect with like-minded people and build communities around shared interests or causes. Activist groups, for instance, often use social media platforms to rally support for important issues, raising awareness and mobilizing action more efficiently than traditional methods.

Moreover, social media serves as a powerful tool for information dissemination. News spreads rapidly through these platforms, allowing individuals to stay informed about current events. During emergencies, such as natural disasters, social media can provide crucial information in real time, helping people stay safe and informed. However, this rapid dissemination of information also raises concerns about the accuracy and reliability of the content being shared. Misinformation can spread just as quickly as legitimate news, leading to confusion and mistrust.

Despite the challenges posed by misinformation, social media plays a significant role in shaping public opinion. People often turn to these platforms to voice their opinions and engage in discussions on various topics. For instance, political debates and social movements frequently gain traction through social media, allowing individuals to express their views and influence others. This democratization of discourse can empower marginalized voices and facilitate social change. However, it is crucial to approach online discussions critically, as echo chambers can form, reinforcing existing beliefs rather than encouraging open dialogue.

In conclusion, while social media presents challenges such as misinformation and polarized discussions, its positive contributions to communication, information dissemination, and social activism cannot be overlooked. As society continues to evolve, it is essential to harness the potential of social media while being mindful of its pitfalls. By promoting responsible use and critical thinking, we can maximize the benefits of social media and foster a more connected and informed society.

Read the following passage about the Exploring The Universe 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 31 to 40.

Science is a vast and fascinating field that seeks to understand the natural world and the universe beyond[I]. It encompasses various disciplines, including physics, chemistry, biology, and astronomy[II]. Each of these areas contributes to our understanding of complex phenomena, [III]. For instance, scientific research has led to significant breakthroughs in medicine, renewable energy, and environmental conservation[IV]. In this essay, we will explore the impact of science on our lives, particularly focusing on space exploration.

One of the most intriguing aspects of science is space exploration. Humans have always looked to the stars, wondering what lies beyond our planet. The launch of satellites and manned missions has allowed us to gather valuable information about the cosmos. For example, NASA's Mars Rover has provided insight into the potential for life on other planets. Through meticulous research and data collection, scientists can analyze soil samples and atmospheric conditions, paving the way for future explorations.

Space exploration also raises critical questions about our existence and the future of humanity. As we continue to advance technologically, the prospect of colonizing other planets becomes more plausible. This endeavor could serve as a solution to the challenges we face on Earth, such as overpopulation and resource depletion. However, ethical considerations must guide these efforts. We must ensure that we do not repeat the mistakes of history, such as the exploitation of natural resources and indigenous populations.

Moreover, scientific advancements have enabled us to develop technologies that enhance our understanding of the universe. Telescopes and space probes allow us to observe distant galaxies, study black holes, and uncover the mysteries of dark matter. Each discovery leads to new questions, further fueling our curiosity and drive for knowledge. The concept of the multiverse, for instance, challenges our understanding of reality and pushes the boundaries of scientific thought.

In addition to exploring the universe, science plays a crucial role in addressing pressing issues on Earth. Climate change, for example, is a significant concern that scientists are actively investigating. Through climate models and data analysis, researchers can predict future trends and propose solutions to mitigate the effects of global warming. Public awareness and education are essential in fostering a collective response to environmental challenges.

As we reflect on the wonders of science, it is clear that its contributions extend far beyond mere knowledge acquisition. Science empowers us to make informed decisions about our health, environment, and future. By fostering a culture of curiosity and critical thinking, we can inspire future generations to continue exploring the unknown.

Read the following passage about Renewable energy sources 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 31 to 40.

          [I] Renewable energy sources, such as solar, wind, and hydroelectric power, have gained global popularity as a sustainable alternative to fossil fuels. [II] Unlike coal and oil, renewable energy generates electricity without releasing harmful emissions, making it a cleaner option for the environment (Jacobson et al., 2017). [III] However, despite the advantages of renewable energy, there are still notable challenges that need to be addressed for it to fully replace traditional energy sources (Ell Abban et al., 2014). [IV]

          One major advantage of renewable energy is its sustainability. Renewable resources, unlike fossil fuels, are naturally replenished and do not deplete over time. For instance, solar power harnesses energy from sunlight, which is virtually endless. In addition, renewable energy contributes to reducing greenhouse gas emissions, which helps combat climate change. Many countries are increasingly investing in renewable technologies to decrease their carbon footprint and meet international climate goals.

          However, renewable energy has certain limitations. One significant issue is its intermittent nature; for example, solar and wind power depend on weather conditions, making it difficult to generate a consistent power supply. This variability can disrupt the energy grid, which relies on a steady supply of electricity to meet demand. Another challenge is the high initial cost of setting up renewable energy facilities. Although prices have decreased in recent years, installing solar panels or wind turbines still requires substantial upfront investment (IRENA, 2019).

          Despite these challenges, advancements in technology are gradually making renewable energy more efficient and accessible. Improved energy storage systems, such as batteries, allow excess power generated during favourable conditions to be stored and used later, ensuring a more reliable energy supply. As technology and infrastructure improve, renewable energy may eventually.
