Read the following passage about Asia’s culture 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] Chemicals are present everywhere in our environment, some of which occur naturally, while others are the result of human activities. [II]. They are found in the air, water, and soil, and can have both positive and negative impacts on the ecosystem. Some chemicals, like nutrients, help support life by promoting plant growth [III]. However, others, especially synthetic chemicals such as pesticides, fertilizers, and industrial waste, can be harmful to both the environment and human health. [IV]

The widespread use of pesticides and fertilizers in agriculture has been a major cause of chemical pollution. When these chemicals are used improperly or excessively, they can wash into rivers, lakes, and oceans, leading to water pollution. This runoff can also contribute to the depletion of oxygen in water bodies, a process known as eutrophication. Eutrophication harms aquatic life, disrupting ecosystems and causing the death of fish and other organisms that rely on oxygen.

Toxic chemicals such as heavy metals (e.g., mercury and lead) pose additional threats to the environment and human health. These substances can accumulate in the food chain, starting from plants and animals in contaminated areas and eventually reaching humans. Long-term exposure to these chemicals can lead to serious health issues, including neurological disorders, cancer, and other chronic conditions. Many countries have established regulations to limit the use of harmful chemicals, but enforcement remains a challenge.

Efforts to reduce chemical pollution involve a combination of government regulations, technological innovations, and public awareness. Governments worldwide have introduced stricter rules on the use of hazardous chemicals and encouraged the development of eco-friendly alternatives. These regulations aim to limit the harmful impact of chemicals on the environment, encouraging industries to adopt safer practices. Environmental organizations play a vital role in monitoring chemical pollution, raising awareness, and advocating for cleaner technologies. They work closely with policymakers to ensure effective enforcement of environmental laws. While progress has been made, ongoing efforts are needed to address emerging challenges and ensure a safer and healthier environment for future generations.

Which of the following best paraphrases the underlined sentence in paragraph III?

"These substances can accumulate in the food chain, starting from plants and animals in contaminated areas and eventually reaching humans."

Read the following passage about Our Festival Traditions 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.

Katê Festival

Cultural diversity is a vital aspect of any society, and festivals of ethnic groups play an essential role in preserving the cultural identity of a community. Embracing cultural values through festivals is an important way of staying connected with one community as well as its history and traditions, and a well-known Katê Festival of the Chăm people in Vietnam is an example to prove so.

The Katê Festival, also known as Mbăng Katê, is the biggest yearly festival for the Chăm people in Vietnam. It is a special time of year when they honour important figures in their history and the dead in their families. The Kate Festival takes place on the first day of the seventh month in the Chăm calendar, usually in September or October. It lasts for three days and takes place around three important ancient structures in Ninh Thuận Province: the Po Klaung Yăgrai Tower, the Po Romé Tower and the Po Inû Nagar Temple. All of these places are very important to Champa culture and history.

On the morning of the first day, Cham families take part in processions as they travel to the towers and temple, bringing gifts of fruit, meat and rice. In a special ceremony, the Cham people receive the costumes of the Goddess Po Nagar from the Raglai people, a cultural group with close connections to Champa culture. The Chăm carry the costumes to the temple to celebrate Po Nagar, then they open the gates. Inside the temple, they start bathing the statues of important figures and watching sacred dances. After those performances, people enjoy lively parties until the evening of the festival's second day.

On the last day, people make special offerings to their gods at community houses in their villages and pray for luck and good health for the coming year. Once this is over, there are traditional music performances, and then people do fun activities like playing football and participating in weaving competitions.

In which paragraph does the passage describe how the festival begins?

Read the following passage about Singapore Science Centre 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.

The Singapore Science Centre, situated on a sprawling six-hectare site in Jurong, offers a captivating way to explore the wonders of science and technology. Here, visitors can engage with interactive exhibits that make learning both fun and memorable. Clap your hands, and colorful bulbs will light up; spin a wheel, and it will activate a fan. This engaging environment sparks curiosity and fuels the imagination of both children and adults.

The centre boasts more than four hundred exhibits across various fascinating topics, including solar radiation, communication, electronics, mathematics, nuclear energy, and evolution. These exhibits are designed to foster interest in science and technology among the public, making the centre a hub for educational exploration.

Notably, it is the first science centre to be established in Southeast Asia. Officially opened in 1977, the centre now welcomes an average of 1,200 visitors daily, highlighting its enduring popularity and educational value.

The exhibits are thoughtfully arranged across four main galleries: the Lobby, Physical Sciences, Life Sciences, and Aviation. To ensure a fresh and engaging experience, the exhibits are renewed annually, encouraging repeat visits. Visitors are encouraged to interact with the exhibits, as opposed to traditional “hands-off” policies in most museums. Here, pushing buttons, turning cranks, or pedaling mechanisms are all part of the fun and learning experience.

The Discovery Centre, added in 1985, is specially designed for children aged three to twelve, providing an exciting space for young minds to explore and experiment. Most recently, a stone-age exhibit was introduced, showcasing extinct animals and early human life, offering insights into prehistoric times.

With its interactive displays and immersive environment, the Singapore Science Centre continues to inspire a love for science and discovery, making it an unforgettable destination for learners of all ages.

In which paragraph is the annual renewal of the exhibits mentioned?
