Read the following passage about Artificial Intelligence 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.

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think, learn, and adapt. AI is applied in various fields, including healthcare, education, transportation, and entertainment. Technologies such as machine learning, natural language processing, and robotics enable AI systems to perform tasks like diagnosing diseases, personalizing education, and even driving autonomous vehicles.

One significant benefit of AI is its ability to enhance efficiency and accuracy. For example, AI-powered systems can analyze vast amounts of data faster than humans, identifying patterns and trends that might otherwise go unnoticed. In healthcare, this means earlier diagnosis and improved treatment plans. In transportation, AI contributes to safer roads with the development of self-driving cars.

Despite these advantages, AI poses several challenges. Concerns include ethical issues, such as bias in algorithms, and the potential loss of jobs due to automation. Cybersecurity risks are also heightened as AI systems become more integrated into critical infrastructure. Addressing these challenges requires transparency, regulation, and collaboration among stakeholders.

To maximize its benefits, society must approach AI development responsibly. Governments, private organizations, and researchers are working together to create ethical guidelines and ensure that AI serves humanity’s best interests. As AI continues to evolve, it holds the promise of transforming the way we live and work.

In which paragraph does the writer discuss the challenges posed by AI?

Read the following passage about Global Challenges Requiring Diverse Solutions and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22.

Climate change affects everyone on our planet, but different communities experience its impacts in unique ways. (18)_________. This traditional wisdom, which connects deeply with nature, can help us find better solutions to environmental problems. If we had started addressing climate change earlier, many environmental disasters could have been prevented. The effects of global warming are now visible in many regions around the world, from melting ice caps to increasing droughts and floods. These changes threaten not only ecosystems but also cultural practices tied to specific environments. Many coastal communities (19)_________, and ancient cultural sites are being damaged by extreme weather events. When diverse communities work together, sharing their unique perspectives and knowledge, innovative climate solutions emerge. Different cultural approaches to agriculture, water conservation, and energy use can inspire new ways of thinking about sustainability. Climate solutions must be culturally appropriate; (20)_________. By combining traditional wisdom with modern science, we create more effective strategies for addressing climate challenges. Communities around the world are already implementing these multicultural approaches, demonstrating (21)_________. People want immediate action on climate change; however, governments often move slowly on environmental policies. Scientists study climate patterns and develop new technologies, (22)_________. The path forward requires collaboration across cultures, disciplines, and borders. Only through inclusive dialogue and shared responsibility can we build a sustainable future that honors both human diversity and our common home.

Read the passage carefully

1. Do you find yourself yawning all day at school? You probably need more sleep. However, it is not just how much sleep you get that is important. What you do before bedtime also has a huge effect on how you feel the next day. If you spend time chatting to someone on social media, or reading a book on your e- reader, you are not alone.

2. All devices' screens give out a large amount of blue light, which affects the body's production of the sleep hormone, melatonin, which can change your sleep patterns. So it is not just getting to sleep that becomes hard, but the quality of your sleep also suffers. The result is that you can wake up several times during the night, and have difficulty getting up in the morning.

3. Sleep is food for the brain, so not sleeping well can be a severe problem for anyone, especially for teenagers, because their brains are still developing. When you do not sleep well, it can be difficult to concentrate at school, which makes it harder to learn and get good grades. It can also affect your mood, making you feel sad or anxious. 

4. So, it is clear you should not use your phone before you go to sleep. Why not leave it in another room? Nothing on social media is so important that it cannot wait a few hours! You should rediscover paper books and enjoy feeling tired and sleepy before bedtime rather than wondering why your best friend has not liked your photo! How will you wake up? You do not have to use the alarm on your phone. Go and buy yourself an old-fashioned alarm clock! The negative effects that screen time is having on sleep have been in the news a lot recently, so manufacturers of smartphones and tablets have added a feature to the mobile devices that can help reduce these. Most new phones have a night-time setting that changes the colour of the screen so that it gives out less blue light. If you really cannot avoid going onto social media at bedtime, think about turning on this setting on your phone.
