Q: Read the following article and answer the question. Article: A lot of people are interested in sea animals, especially the ones that are beautiful and smart. Although some are wild, and can be deadly, each is also unique in its own way. Whales, sharks and dolphins are the main subjects of sea-animal research, with dolphins standing out from whales and sharks for their friendly behavior with humans. No doubt the desire to learn some interesting things about dolphins has led you to this article, and you too are eager to know more about these sea creatures. It is sometimes believed that Dolphins have been evolved from land mammals . Among sea mammals, dolphins are the most advanced in intelligence. You may be surprised to learn that they are close s of camels and cows. The debate on the origin of the dolphin is an unending one, however. Some believe that they evolved from land-based hoofed mammals, others believe that they evolved from other different kinds of mammals many millions of years ago. There are about 32 types of dolphins that live in salt water, each unique in its color1 and body shape. Five other types live in fresh water. A grown-up dolphin eats nearly 20 to 22 kilos of fish every day. The eating habits of dolphins depend on where they live, and on the season. Seasons in which fish are abundant are like party time for dolphins. Dolphins decide how much they are going to eat based on the fat content of the fish available. They've a good sense of understanding about their hunger. The social skills and intelligence of dolphins make them very attractive for zoos and aquariums, where they are often trained to show off their diving skills. Dolphins also communicate with each other by special sounds. Question: Scientists like to research dolphins mainly because _ . Answer: | OPTIONS:
- they are friendly to humans
- they have good diving skills
- they have unique bodies
- they are beautiful and clever
A: they are friendly to humans

Q: Read the following article and answer the question. Article: Do you have an emotional brain or a rational one? Researchers at Australia's Monash University have found actual difference in the brains of people who respond emotionally to others' feelings compared with those who respond more rationally. A study published in the journal NeuroImage has looked at whether people who have more brain cells in certain areas of the brain are better at certain types of empathy, according to Science Daily. Empathy is the ability to understand and share the feelings of another person, and the two types investigated were cognitive empathy and affective empathy. "Every day people use empathy with, and without, their knowledge to get around in the social world," said Robert Eres from Monash University's School of Psychological Sciences. "We use it for communication, to build relationships, and to increase our understanding of others." "People who are high on affective empathy are often those who get quite fearful when watching a scary movie, or start crying during a sad scene. Those who have high cognitive empathy are those who are more rational, for example a psychologist helping someone," explained Eres. The results of the study showed that people with high scores for affective empathy had more gray matter in a part of the brain called the insula, found right in the "middle" of the brain. Those who scored higher for cognitive empathy had more in a part called the midcingulate cortex--an area above the corpus callosum, which connects the two halves of the brain. The discovery "raises new questions--like whether people could train themselves to have more empathy, and whether those areas of the brain would become larger if they did, or whether we can lose our ability to empathize if we don't use it enough", according to Science Daily. "In the future we want to investigate further by testing whether training people in empathy-related tasks can lead to changes in these brain areas. We also want to investigate if damage to these brain areas, as a result of a stroke for example, can... Question: What does the research done by Monash University mainly show? Answer: | OPTIONS:
- Differences in the brains of emotional and rational people.
- Whether a rational brain works better than an emotional one.
- What empathy is and how to improve people's ability to empathize.
- How to effectively train people to have more empathy cells in their brain.
A: Differences in the brains of emotional and rational people.

Q: Read the following article and answer the question. Article: In 2006, the UK government started to allow universities in England and Wales to charge British students tuition fees. More than 80 percent of students in England and Wales now take out a student loan in order to go to university. They use the loan to pay for tuition fees, books and living expenses. Although the interest on student loans is quite low, it begins as soon as the student receives the loan. The average student in England and Wales now graduates from university with debts of around PS12,000. Students of medicine usually have debts of more than PS20,000. That is a lot of money. It means graduates cannot afford to buy a house for many years. They even struggle to pay rent on a flat, because they have to start paying back the student loan after graduating. If you start to earn over PS15,000 a year, the government takes repayments directly from your monthly salary. Is it any surprise, therefore, that the average British person does not leave their parents' home until they are 30 years old? You might think that a British person with a degree will find it easy to get a well-paid job. However, most people in white-collar jobs seem to have a degree these days, so there is a lot of competition. Also, British companies tend to value work experience over a piece of paper. Like everyone else, graduates usually have to start at the bottom and work their way up. That can be very frustrating for them, since they are often over-qualified for the work they are doing. While at university, they have dreams of getting an exciting, challenging job. Therefore, life after university ends up being quite disappointing for a lot of graduates. All of the above is beginning to make British people question whether a university degree is really worth the money. Question: We can infer from the passage _ Answer: | OPTIONS:
- The average British person didn't leave their parents' home until they are35 years old
- Having a degree doesn't get aBritish person a good job
- Students are graduating without larger and larger debts.
- things are easier for students from other countries coming to studyin the UK without money
A: Having a degree doesn't get aBritish person a good job
