Read the following passage about a multicultural 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.

[I] In today’s interconnected world, multiculturalism has become increasingly prevalent as people from diverse cultural backgrounds live and work together in the same communities. [II] Multiculturalism fosters cultural diversity, promoting understanding and tolerance among individuals with different perspectives and traditions (Banks, 2015). [III] However, while multiculturalism brings many benefits, it also poses certain challenges that need to be addressed to achieve a harmonious society (Parekh, 2000). [IV]

One of the key benefits of multiculturalism is the enrichment of society through diverse perspectives. Different cultural backgrounds contribute unique ideas, art forms, and traditions, which can lead to a more vibrant and innovative community. For instance, diverse viewpoints in the workplace often drive creativity and lead to better problem-solving solutions. Additionally, exposure to various cultures can increase people's awareness and acceptance of others, thus reducing discrimination and promoting social cohesion.

However, a multicultural society is not without its challenges. Language barriers, for example, can hinder communication and understanding among individuals. Miscommunication due to language differences can lead to misunderstandings or even conflicts. Furthermore, people may feel divided by their cultural identities, which can create a sense of "us versus them." Some argue that without efforts to bridge cultural differences, multiculturalism might unintentionally lead to social fragmentation (Modood, 2007).

To foster a successful multicultural society, it is essential to promote inclusive policies and encourage intercultural dialogue. Schools and workplaces can play a significant role by celebrating diversity and teaching cultural understanding. When people actively engage with different cultures, they are more likely to find common ground and develop mutual respect, which helps create a stronger, more unified community (Berry, 2011).

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.

The word "exacerbates" in paragraph 3 is closest in meaning to: _______.
