Read the article and select the best answer. Article: In the United States, 30 percent of the adult population has a "weight problem.". To many people, the cause is clear: We eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were slimmer than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch television. Several modern studies, moreover, have shown that fatter people don't eat more on average than thinner people. In fact, some investigations (researches), such as a 1970 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people. Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts. The more the men ran, the greater loss of body fat. The more they ran, the greater their increase in food intake . Thus those who ran the most ate the most, yet lost greatest amount of body fat. Question: What have modern medical and scientific researches reported to us? Options: A: Fat people eat less food and are less active. B: Fat people eat more food than slim people and are less active. C: Fat people eat more food than slim people but are less active. D: Thin people run less, but have greater increase in food intake

You would probably vote to _ don't you think? Well, more often than not, you'd be wrong. A few years ago, an experiment was done on an evening news show on WNBC in prefix = st1 /New York. Viewers were shown a film of what seemed to be a mugging. In this simulation, a man snatched a woman's purse. He then knocked her down and ran face forward at the camera so that the viewers got a good look at him. Viewers were then shown a lineup of six men. They were asked to decide if the mugger was in the lineup and, if so, to tell which one he was. In effect, then, they had seven choices. The suspect was either one of the six or he wasn't even in the lineup. Of the 2,145 people who called up to respond, 1,843 were wrong. That means about one in seven was right. This is what you'd expect from random choice. Eyewitness accounts can be the most convincing evidence presented to a jury. Yet we are finding out that such accounts can be faulty. Something is just wrong. Why is this so? Recent findings have removed doubts on whether memory can last long. We also know that it can be changed by things such as leading questions. Mistaken eyewitness accounts are common. They are also the major cause of innocent persons being convicted in the United States. Question: Of the people who called up to respond, _ . Options: A: half of them were right B: 2,145 were on a jury C: six out of seven were wrong D: 1,843 made seven choices

Q: Read the article and select the best answer. Article: Confucius was born five hundred and fifty years before Christ. Unlike Jesus Christ, he did not bring words of God to the people. He was a clever teacher and a philosopher, looking for truth and wisdom. Most of his teaching was about life in this world. Confucius was very keen to give people good rulers. Someone asked him, "What does a country need?" Confucius answered, "Enough food, a good army, and a good leader." The people then asked, "Which one is the most important?" Confucius answered, "An army is not very important. All men must die, so food is not the most important. But if the leader of the country is not good, then everything will be bad," Question: Confucius taught people all these things except _ . Options: A: how to live in the world B: the importance of the leader of the country C: any ideas about God D: how to make good judgements
A: C

Question: Read the article and select the best answer. Article: "If music is the medicine of the soul , let it play on," said a famous person. I think he said so because probably he got some help from music. Music has some strange abilities. Medical scientists have found that a person that feels stressed can actually listen to some kind of music and become well. The researchers said that since stress comes as a result of life events such as starting a new family, starting a new business, and starting a new job, one can actually listen to good music and feel good because good music touches the human mind in a positive way. Music helps you to forget the life events that make you worried and remember the important events that once happened in your life. Depression is a disease cause by stress, smoking, social problems and so on. Depression is also caused by problems such as failure in business. Depression may bring us weakness, headache, and loss of concentration. Good music makes one remember happy moments or good days. If you play music about love, it makes you feel like falling in love again though you may have had several upset experiences. And such good feeling make you healthy. Anxiety is another health problem that can be controlled by music. Anxiety is a side effect of some major health problems such as cancer of the liver and cancer of the breast. Good music makes you feel relaxed and removes the pains from these diseases and you feel all right. Good music can send you to sleep. And you need to know that sleep puts your body in a healthy condition. Sleep takes away the effects of stress, depression and anxiety from a person. Question: According to the passage, one who has cancer will most probably experience _ . Options: A: stress B: depression C: anxiety D: upset
Answer: C

Read the article and select the best answer. Article: Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game. Why is poker so difficult? Chess and Go are "information complete" games where all players can see all the relevant information. In poker, other players' cards are hidden, making it an "information incomplete" game. Players have to guess opponents' hands from their actions--tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars. Scientists believe it is only a matter of time before AI once again _ humans, hence our human-machine match comes up in a game of Texas Hold's Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural networks and reinforcement learning . Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better. Mr Heinrich told Sky News: "Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations." After two hours of quite defensive play, from the computer at least, we called it a draw. Question: Why can't the computer beat humans at the poker game? Options: A: Because humans are cleverer than the computer. B: Because humans practice playing the poker game every day. C: Because the computer can't learn the regular rules of the poker game. D: Because the computer can't know the other players' cards completely.
