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.

In which paragraph does the writer mention what three methods are used by cultural ambassadors to achieve their goals?

Read the following passage about Wildlife Conservation in Africa 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.

Wildlife conservation in Africa is vital for preserving biodiversity and ensuring the survival of iconic species such as elephants, lions, and rhinos. [I] The continent is home to some of the world’s most diverse ecosystems, including savannahs, rainforests, and deserts. [II] Conservation efforts involve strategies like protecting habitats, combating poaching, and raising awareness about the importance of wildlife. [III] Despite challenges, success stories demonstrate the positive impact of these efforts. [IV]

One notable example comes from Kenya, where anti-poaching initiatives and community engagement have helped stabilize elephant populations in Amboseli National Park. Similarly, in South Africa, rhino conservation programs use advanced technologies like drones and GPS tracking to monitor and protect vulnerable animals. These efforts not only safeguard wildlife but also promote eco-tourism, which supports local economies.

However, wildlife conservation in Africa faces persistent threats. Habitat loss due to agricultural expansion and urbanization continues to endanger species. Climate change exacerbates these challenges, altering migration patterns and threatening ecosystems. Furthermore, poaching and the illegal wildlife trade remain significant concerns, driven by global demand for products such as ivory and rhino horn.

To overcome these challenges, conservationists emphasize the need for international collaboration and local community involvement. Initiatives like eco-tourism provide financial incentives for communities to protect wildlife. Governments, NGOs, and individuals must work together to ensure the survival of Africa’s unique species for future generations.

According to paragraph 2, which of the following is NOT a benefit of conservation efforts?

Read the following passage about world festivals and mark the best answer to the questions from 11 to 18. 

     World festivals have a big impact on young people today. Festivals such as Christmas, Diwali, Halloween, and Chinese New Year are celebrated across the globe, bringing people together. Young people especially enjoy these events because they offer a chance to have fun, learn about different cultures, and develop a global mindset.

     Festivals help young people appreciate diversity. Attending a festival from another culture teaches them new traditions, food, music, and art. For example, attending the Rio Carnival or the Holi Festival of Colors can give young people an exciting experience of new cultures. They learn to respect and understand people from different backgrounds, which is important in today’s world.

     Another impact is that festivals allow young people to express themselves creatively. Many festivals include costumes, dances, and music that encourage self-expression. For instance, during Halloween or a music festival like Coachella, young people often wear creative outfits or costumes that reflect their personalities. This makes them feel confident and allows them to experiment with new styles.

    Festivals also offer opportunities for young people to connect with others. Meeting people at festivals, whether in person or online, helps them build friendships and networks. Social media plays a big role in this, as many young people post about their experiences, spreading awareness of the festivals they attend.

     Overall, world festivals provide many learning and social experiences for young people, helping them grow into more open-minded and creative individuals.
