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 urban shift 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. (2,5 points)

            [I] Water is one of the most essential resources on our planet, vital for all forms of life. However, increasing demand and pollution are putting immense pressure on our freshwater supplies. [II] According to recent studies, nearly 2 billion people worldwide live in countries experiencing high water stress, leading to a decline in the availability of this precious resource. This situation not only affects drinking water but also agriculture, sanitation, and energy production.

            The primary causes of water scarcity include population growth, urbanization, and climate change. As cities expand, the demand for water increases significantly. Moreover, agricultural practices that rely heavily on water are becoming unsustainable in many regions. Climate change further exacerbates these issues, causing unpredictable weather patterns and extreme droughts, which reduce water availability.

           [III] In response to this growing crisis, everyone must prioritize water conservation. Simple actions, such as fixing leaks, using water-efficient appliances, and practicing mindful consumption, can make a significant difference. Additionally, implementing policies that promote sustainable water management and investing in technologies for water recycling can help mitigate the impacts of water scarcity. [IV]

            Despite these efforts, the challenges remain substantial. It is crucial that we recognize the importance of conserving water and take immediate steps to protect this vital resource for future generations.
