Read the following passage about the impact of social media on mental health 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] In recent years, social media platforms have become a central part of daily life, offering users countless ways to connect, share, and communicate. [II] While these platforms offer many advantages, experts have noted rising concerns about their effects on mental health, particularly among young people (Smith & Anderson, 2018). [III] Studies reveal that excessive social media use can contribute to feelings of anxiety, depression, and loneliness, despite its intention to promote connection and social interaction (Twenge & Campbell, 2019). [IV]

          A primary reason for these mental health concerns is the tendency for social media users to compare themselves to others. Platforms like Instagram and Facebook often highlight idealized lifestyles, leading users to feel inadequate about their own lives. Additionally, the constant notifications and messages contribute to a "fear of missing out," or FOMO, which keeps individuals in a cycle of checking their phones, often reducing the quality of sleep and overall well-being.

          There is also a growing body of research suggesting a link between social media use and decreased attention spans. When users frequently switch between apps and notifications, their ability to focus for extended periods may diminish (Rosen, 2019). This shift in attention can interfere with productivity, especially in academic and professional settings, where sustained focus is essential.

          Addressing these challenges requires a multi-faceted approach. Some mental health professionals suggest limiting screen time and setting boundaries, such as "device-free" hours before bedtime. Others recommend engaging in offline activities, like reading or exercising, to reduce dependence on social media and build healthier habits. According to psychologists, such strategies can enhance mental resilience and allow for more meaningful, balanced relationships (Robinson & Smith, 2020).

Read the following passage about Traveling 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 23 to 30.

          Traveling and exploring new places is an exciting way to experience different cultures and expand one’s horizons. Whether it’s a short trip to a neighbouring town or a long journey to a foreign country, stepping out into the world offers numerous benefits. It allows individuals to gain new perspectives, meet diverse people, and create lasting memories. Additionally, traveling can enhance personal growth and provide a sense of adventure and fulfillment.

          One of the key advantages of traveling is the opportunity to learn about different cultures. By immersing oneself in a new environment, travellers can gain a deeper understanding of local customs, traditions, and lifestyles. This cultural exchange fosters mutual respect and appreciation among people from different backgrounds. Moreover, experiencing different cultures can challenge preconceptions and broaden one’s worldview.

          Traveling also promotes personal development. Facing unfamiliar situations and overcoming challenges can boost confidence and adaptability. Travelers often find themselves  navigating new cities, trying unfamiliar foods, and communicating in foreign languages. These experiences can enhance problem-solving skills and resilience. Furthermore, the sense of accomplishment from successfully managing a trip can lead to increased self-esteem and a greater sense of independence.

          Another benefit of traveling is the chance to disconnect from the routine of everyday life. Exploring new places provides a break from the usual responsibilities and stresses. This can be refreshing and rejuvenating, allowing individuals to return home with a renewed sense of energy and perspective. Travel can also foster creativity by exposing individuals to new sights, sounds, and ideas.

          Despite its benefits, traveling can also present challenges. Planning a trip requires time and effort, and unexpected situations can arise. However, these challenges can be viewed as opportunities for growth and learning. With careful planning and a positive mindset, the rewards of traveling far outweigh the difficulties.

Which of the following is NOT mentioned as a benefit of traveling?

Read the following passage about the Pathways from Today's Actions to Tomorrow's World 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.

As we stand at the crossroads of environmental decision-making, the actions we take today will shape our world in 2050. Scientists warn that we're skating on thin ice with current consumption patterns and carbon emissions. Global temperatures could rise by 2-4 degrees Celsius unless significant changes occur within the next decade. Many countries have pledged to achieve carbon neutrality by 2050, but these promises require immediate implementation. Individual choices in transportation, energy usage, and consumption can collectively influence whether future generations inherit a sustainable planet or face severe climate consequences.

[I] Technological innovation represents our greatest hope for addressing environmental challenges by 2050. [II] Renewable energy sources like solar and wind are becoming increasingly affordable, potentially replacing fossil fuels entirely within thirty years. [III] Electric vehicles may dominate transportation networks, while vertical farming could transform food production in urban areas. [IV] However, these technological solutions must be developed and deployed equitably to avoid creating new disparities between wealthy and developing nations.

Social structures will undergo dramatic transformation by 2050 as demographic shifts reshape communities worldwide. Aging populations in developed countries will necessitate new approaches to healthcare, retirement, and social support systems. Meanwhile, climate migration may force millions to relocate from vulnerable coastal and drought-prone regions. Education systems must evolve to prepare our students for jobs that don't yet exist, emphasizing their adaptability and lifelong learning. Cities will need to become more resilient, incorporating green spaces and sustainable infrastructure to support growing populations.

Economic models must fundamentally change by 2050 to balance prosperity with environmental responsibility. The traditional focus on continuous growth may shift toward measuring success through wellbeing indicators rather than GDP alone. Circular economy principles will likely replace linear production models, with products designed for reuse and recycling. Resource-sharing platforms may become more prevalent, reducing individual consumption while maintaining living standards. Companies implementing genuinely sustainable practices will thrive, while those clinging to environmentally harmful methods may disappear entirely. The transition presents both challenges and opportunities for businesses willing to embrace innovation and sustainability.

Where in paragraph 2 does the following sentence best fit?

Artificial intelligence systems will likely revolutionize resource management, reducing waste significantly across industries.
