Read the following passage about Building Understanding Across Nations 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.
In our interconnected world, cultural ambassadors play a vital role in bridging the gaps between different nations and peoples. These dedicated individuals and groups serve as links between cultures, fostering mutual understanding and respect through various activities and programs. Their mission is to showcase their own cultural heritage while learning about and appreciating others, creating pathways for meaningful dialogue and lasting connections across borders.
Cultural ambassadors employ numerous methods to achieve their goals. They organize traditional festivals and art exhibitions that display unique customs, allowing visitors to experience different cultures firsthand. Language exchange programs enable people to communicate more effectively, while cultural workshops teach traditional crafts, music, and dance. These ambassadors also utilize digital platforms to reach wider audiences, sharing stories and traditions through social media and online events that connect people from different corners of the world.
Despite their important work, cultural ambassadors face several challenges in their mission. Stereotypes and prejudices can create barriers to understanding, while language differences sometimes lead to misunderstandings. Limited resources and funding may restrict their activities, and political tensions between nations can complicate their efforts. However, these dedicated individuals persist in their work, believing that personal connections and shared experiences can overcome these obstacles and promote harmony among different communities.
Looking ahead, the role of cultural ambassadors becomes increasingly significant in our global society. Their efforts to build bridges between nations contribute to reducing conflicts and fostering peace. Through their continued dedication to promoting cross-cultural understanding, these ambassadors help create a more inclusive and connected world where differences are celebrated rather than feared. This ongoing process of cultural exchange remains essential for building a future based on mutual respect and cooperation.
Which of the following is NOT mentioned as a method used by cultural ambassadors?

Read the following passage about the Designing Spaces That Connect Us to Nature 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.
Biophilic design has been turning heads and winning hearts by incorporating natural elements into our living and working spaces. This approach recognizes our innate connection to nature and how it affects our well-being. Studies show that exposure to natural light, plants, and natural materials can reduce stress and improve productivity. Many modern architects now integrate gardens, water features, and large windows into their designs. These elements help create environments where people can thrive both mentally and physically. As one designer put it, "We're bringing the outside in to help people feel at home in their skin."
The benefits of biophilic design extend beyond aesthetics. [I] Hospitals with views of nature report faster patient recovery times. Office buildings with natural elements see decreased absenteeism and increased worker satisfaction. [II] Schools incorporating biophilic principles observe improved student concentration and academic performance. [III] Even retail spaces benefit, with customers spending more time and money in naturally-designed environments. These practical advantages explain why biophilic design is gaining momentum across various sectors. [IV]
Implementing biophilic design doesn't require elaborate renovations. Simple changes like adding houseplants, using natural materials, or rearranging furniture to maximize natural light can make significant differences. Even artificial representations of nature, such as nature photography or recordings of birdsong, provide some benefits. The key is creating spaces that stimulate our senses in ways that remind us of natural environments. This approach works in urban apartments, suburban homes, and rural settings alike. As cities grow denser, these natural connections become increasingly valuable for maintaining our psychological health.
Looking ahead, biophilic design will likely become standard practice rather than a luxury option. Climate change concerns are pushing architects to create buildings that not only connect with nature but also protect it. Living walls that purify air, rooftop gardens that reduce energy consumption, and materials that sequester carbon are becoming more common. These innovations represent a shift from merely appreciating nature to actively participating in its preservation. By designing spaces that honor our biological need for natural connection, we create environments that support both human and planetary health for generations to come.

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
[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 bu mental resilience and allow for more meaningful, balanced relationships (Robinson & Smith, 2020).
