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.

Read the following passage about food addiction 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.

Few people would disagree that one of the world's most popular dishes is pizza. Twenty-two-year-old Zack certainly wouldn't. He would eat a variety of pizza-based items, including homemade pizza, precooked microwave pizza, and even pizza leftovers from the night before. He was consuming 800kg of pizza a year. As a child, Zack had eaten a wide variety of food. But he became addicted to pizza when he started secondary school. American school meals have often been criticised for the large amount of fast food present on the menu, and pizza is the star dish. Zack even spent all his pocket money on slices of pizza.

Naturally, Zack's family worried about his high-calorie, low-vitamin diet. So did Zack. In an attempt to break his addiction, Zack agreed to appear on a TV programme called Freaky Eaters. Its aim was to encourage food addicts to beat their addictions with the help of a psychologist and nutritionist. It wasn't easy. He had to eat a fish dish, while his brother sat in front of him enjoying... a pizza! However, Zack met the challenge and has never eaten pizza again.

Seventeen-year-old Stacy Irvine's friends visit her and discover that she has been rewarded thousands of free toys from fast food restaurants as a regular customer. Stacy's mother often gave her two-year-old girl a portion of fried chicken in a McDonald's restaurant. [I] Since then, Stacy has refused to eat anything else except for pieces of fried chicken, and as a result, her diet has created serious health. She has been warned that if she doesn't change her diet, she will die. [II] Stacy once collapsed due to lack of vitamins and nutrients and needed to be hospitalised. [III] She insisted that Stacy adopt a healthier lifestyle. However, worryingly, Stacy's mother said that while Stacy was beginning to understand the seriousness of her situation, she couldn't eat anything else but chicken nuggets. [IV]

Twenty-year-old Hanna Little was keen on chips. The only thing that Hanna consumed for fifteen years was one plate of chips after another. Not surprisingly, a diet that contained few nutrients and an excess of fat and carbohydrates could only have negative consequences. And it did because not only did Hanna develop health problems, but she also had to leave her job after collapsing at work. At five, Hanna became addicted to chips and refused to eat fruits and vegetables despite her mother's efforts. Hanna says that she was terrified of tasting the flavour of different types of food and she would feel anxious just at the idea of doing it. Parties, picnics and barbecues with friends and family used to be a nightmare. Furthermore, Hanna was soon seen as 'odd' by her friends' parents.

It wasn't until the age of sixteen that Hanna realised she had Selective Eating Disorder (SED). Despite this new knowledge, no solution was found. It wasn't until she lost her job before she started eating normally. Hanna sought therapy from psychologist Felix Economakis, who used hypnosis, a treatment that none of the doctors that she had seen before had mentioned, to get her to eat fruit after one one-hour session, and since then she has been willing to eat anything.... including chips!

Read the following passage 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 22nd Southeast Asian Games were held in Vietnam from December 5th to 13th, 2003. It marked the first time Vietnam hosted such a significant sporting event, yet the Games were a great success. They became a grand festival that impressed sports enthusiasts with their spirit of solidarity, cooperation for peace, and development. The event demonstrated Vietnam's capability to unite the region through sports.

Athletes from 11 participating countries competed in 32 sports, winning a total of 444 gold medals. Teams in table tennis, badminton, karate, volleyball, basketball, and wrestling showcased some of the region’s top competitors. Notably, many records set during the Games were close to international standards. Vietnam emerged victorious, securing 158 gold medals and finishing at the top of the medal standings. Thailand came second with 90 golds, while Indonesia ranked third with 55. Singapore and Vietnam were the only nations with participants honored as the Most Outstanding Athletes in Swimming and Shooting events.

In football, the Vietnamese Women's Football team successfully defended their SEA Games title, a moment of pride for the host nation. In the Men's Football Final, Vietnam faced Thailand but lost, with the Thai team taking home the gold medal. Other sports, such as karate, athletics, bodybuilding, and wushu, saw young and talented Vietnamese athletes delivering exceptional performances and securing numerous gold medals. The strong performance of the athletes reflected Vietnam's growing prowess in the regional sports arena.

Vietnam’s first-place finish was not surprising. To prepare for the 22nd SEA Games, the country implemented an intensive training program for its athletes, involving both domestic and international facilities. Furthermore, the enthusiastic support from the Vietnamese people inspired the athletes to compete in high spirits. This success solidified Vietnam’s reputation as an excellent host for international sporting events. With this achievement, Vietnam has demonstrated its potential to host even larger competitions, such as the Asian Games, in the future.

The word “their” in paragraph 3 refers to:
