Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question

Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15-20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20 years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent

Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam's labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.

Which statement is TRUE about raising the retirement age in the second paragraph?

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!

The doctor who treated her said she had never seen such an extreme case of food addiction.

Read the following passage about wildlife conservation 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] Wildlife conservation refers to the efforts made to protect and preserve wild animal species and their habitats. [II] It is crucial for maintaining biodiversity, which plays a vital role in ecosystem stability and health (Smith & Jones, 2018). [III] Unfortunately, many species are threatened due to habitat destruction, poaching, and climate change, making conservation efforts more urgent than ever. [IV]

One of the primary reasons for wildlife conservation is the preservation of biodiversity. A diverse range of species contributes to ecosystem services, such as pollination, water purification, and climate regulation. The loss of a single species can disrupt these services and lead to ecological imbalances. For instance, the decline of pollinators like bees has serious implications for food production and agriculture (Global Biodiversity Outlook, 2020).

Moreover, wildlife conservation has significant economic benefits. Many communities depend on ecotourism, which relies on healthy wildlife populations and intact ecosystems. According to a study by the World Wildlife Fund (WWF), ecotourism can generate billions of dollars in revenue, providing jobs and supporting local economies (WWF, 2021). Protecting wildlife not only safeguards natural resources but also creates sustainable livelihoods for local populations.

However, effective wildlife conservation requires a collaborative approach. Governments, non-governmental organizations, and local communities must work together to implement policies and strategies that promote conservation efforts. Community-based conservation initiatives, where local people actively participate in protecting their natural resources, have shown promising results. These initiatives empower communities and ensure that conservation efforts are tailored to local needs and contexts (Bennett & Dearden, 2014).

According to paragraph 2, which of the following is NOT a reason for wildlife conservation?
