Water pollution can be caused by a variety of things. Firstly, sewage is dumped directly into the seas without being treated properly. This is a global problem, with equally significant challenges in high-, middle-, and low-income countries. Sewage pollution has reduced the water quality and posed several threats to human health. Secondly, cruise ships release a large amount of garbage into the ocean every year. 40 percent of cruise ships depend on 30-year-old waste treatment technology, leaving sewage with high levels of bacteria, heavy metals and other pollutants that are harmful to aquatic life and people. The third reason is oil spills. Oil spills happen in many different ways. Most of these spills are small and happen accidentally, for example oil spills while refueling a ship. But these spills can still cause damage, especially if they happen in sensitive environments. Large oil spills are disasters. These tend to happen when pipelines break, or big oil tankers sink. The negative effects of oil spills on the ecosystems and economies can be seen for decades following a large oil spill.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions from 31 to 36.

In today's rapidly advancing world of technology, one field that has captured the imagination of people everywhere is artificial intelligence (AI). AI refers to the ability of machines and computers to perform tasks that typically require human intelligence, such as learning, problem-solving, and decision-making.

One of the most exciting aspects of AI is the way it is transforming our lives. From personalised recommendations on our favourite streaming platforms to self-driving cars navigating the roads, AI is becoming increasingly integrated into our daily activities. This is thanks to the development of machine learning, a type of AI that allows systems to learn and improve from data without being explicitly programmed.

However, the integration of AI technology also raises important questions. There are concerns about privacy, the potential for bias, and the impact on jobs as AI systems become more advanced. It is crucial that we address these concerns and ensure that the benefits of AI are distributed fairly and its risks are minimised.

Despite these challenges, the potential of AI to improve our lives is undeniable. In fields like healthcare and scientific research, AI has the power to make groundbreaking discoveries and enhance our well-being. As we continue to explore the frontiers of AI, it is essential that we do so with a focus on ethics, transparency, and the betterment of humanity.
