Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on test, a new study finds. So a Montana teen, Colin decided to test that. They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it. In the first part, the participants had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions. During a new set of readings, the brothers sent messages to the participants' cell phones every 90 seconds. In each message, there were questions that required a reply. Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part. The brothers presented details of their findings at the Intel International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn't do any better than younger ones. And it didn't matter if a student thought he was good at multitasking. On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly. "Our teachers are very happy to see these results," says Coler. The teens' new data strongly support their teachers' opinion that texting while studying is a serious distraction. Question: The brothers' findings were related to participants' _ . Options: A: reading performance B: quality C: writing ability D: reading speed
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Nuclear radiation has a certain mystery, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around but we can't detect them or sense them without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents. Question: According to the passage, the danger of nuclear power lies in _ . Options: A: nuclear mystery B: radiation detection C: radiation level D: nuclear radiation
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: The Taj Mahal is a love story, a sad and beautiful one. If it didn't exist, we would easily imagine that the story of its construction was simply a fairy tale. Three hundred years ago, there lived an Indian emperor called Shah Jahan. His wife was a beautiful and bright woman whom he loved greatly. Her title was Mumtazl Mahan: its shortened form Taj Mahan, means "pride of the palace". In the year 1630 this beloved wife of the emperor died. He was so brokenhearted that he thought of giving up his throne. He decided out of his love for his wife, to build her the most beautiful tomb that had ever been seen. He summoned the best artists and architects from India, Turkey, Persia and Arabia and finally, the design was complete. It took more than twenty thousand men working over a period of 18 years to build the Taj Mahan, one of the most beautiful buildings in the world. The building itself stands on a marble platform 29 meters square and 6-7 meters high. Towers rise from each of the four corners. The Taj itself soars another 61 meters into the air. It is an eight-sided building made of white marble. The emperor planned to build an identical tomb of black marble for himself on the other side of the river connected by a silver bridge. However his son put him into a prison in the palace before he could finish, and for the rest of his life, he could only gaze across river at the tomb of his beloved wife. Question: The emperor _ . Options: A: died soon after Taj Mahan died B: was killed by his son C: was beloved by his people D: died after 1648
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Everybody is happy as his pay rises. Yet pleasure at your own can disappear if you learn that a fellow worker has been given a bigger one. Indeed, if he is known as being lazy, you might even be quite cross. Such behavior is regarded as "all too human", with the underlying belief that other animals would not be able to have this finely developed sense of sadness. But a study by Sarah Brosnan of Emory University in Atlanta, Georgia, which has just been published in Nature, suggests that _ , as well. The researchers studied the behaviors of some kind of female brown monkeys. They look smart. They are good-natured, co-operative creatures, and they share their food happily. Above all, like female human beings, they tend to pay much closer attention to the value of "goods and services" than males. Such characteristics make them perfect subjects for Doctor Brosnan's study. The researchers spent two years teaching their monkeys to exchange tokens for food. Normally, the monkeys were happy enough to exchange pieces of rock for pieces of cucumber. However, when two monkeys were placed in separate and connected rooms, so that each other could observe what the other is getting in return for its rock, they became quite different. In the world of monkeys,grapes are excellent goods (and much preferable to cucumbers). So when one monkey was handed a grape in exchange for her token, the second was not willing to hand hers over for a mere piece of cucumber. And if one received a grape without having to provide her token in exchange at all, the other either shook her own token at the researcher, or refused to accept the cucumber. Indeed, the mere presence of a grape in the other room (without an actual monkey to eat it) was enough to bring about dissatisfaction in a female monkey. The researches suggest that these monkeys, like humans, are guided by social senses. In the wild, they are co-operative and group-living. Such co-operation is likely to be firm only when each animal feels it is not being cheated. Feelings of anger... Question: What can we infer about the monkeys in Sarah's study? Options: A: The monkeys can be trained to develop social senses. B: The monkeys may show their satisfaction with equal treatment. C: They usually show their feelings openly as humans do. D: Cooperation among the monkeys remains effective in the wild.
