Q: I'm taking a test and have to guess the right answer to the question after the article. Article: It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study. The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centres are set up. In their study, the researchers examined groups of nine-month-old babies in New South Wales and Britain. And they came across astounding results. It was found that infants had "social brains" and focused not just on their mothers but on social life in groups as well. "They communicate with more than one baby at once, and show jealousy and generousness," said Professor Bradley. He added, "They develop their own meanings through group interaction, they notice if a group member is behaving differently and they take on roles, such as leaders and followers." "A baby who has a depressed mother tends to be withdrawn ( ), but put that same baby in a group of its peers and they behave and interact like any other baby." It was the first all-baby group study ever to be conducted. "Most studies of babies concentrate on the infant-mother relationship, assuming that is the single foundation for mental health, but babies are constantly involved with groups of people other than their mothers, fathers, siblings, grandparents and those taking care. Therefore, the mother-baby approach needs to be combined with a group approach," said Bradley. Phoebe Christison, a child-care worker at Camperdown Sunshine Bubs in Sydney's inner west, said she often noticed what appeared to be emotional attachments developed between toddlers. She said, "Joel ( 10 months ) and Isabella ( 11 months ) always like to hold hands when they sit in their high chairs and eat. And babies definitely show jealousy. They push and touch each other, and copy what the other is doing." Question: A baby who has a depressed mother _ . Options: A: tends to be a follower B: also enjoys group interaction C: has poor social ability D: pays more attention to its mother
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Dust on furniture may be bad news for waistlines . But it's far too early to add dusting to a weight-loss plan. Dietary fats and other materials that make up indoor dust can send a signal to human fat cells, telling them to grow. That process, in turn, might slow the body's rate of burning energy. Such changes could add to any weight problems a person might have. "We don't know what that means to long-term health and certain diseases yet," says Heather Stapleton, one of the study's authors. But she notes that her team's findings also raise a question of whether pollutants in dust might play some role in the growing, global problem of obesity . Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein called PPAR-gamma 1. It's found in many human tissues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed by people or pets. "While the findings are amazing," says Mitchell Lazar, another study author, "these findings need to be taken as very limited." Indeed, he adds several cautions about how the findings should be understood. "For one thing, people eat these fats in foods all of the time. That is likely to be a lot more than would be consumed from indoor dust," he said. Question: What's the best title for the text? _ Options: A: Can house dust make us fat? B: Why is it important to clean? C: Anything to do to deal with dust? D: What is the best way to lose weight?

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: There are many rights to make sure that people will be treated fairly when they are suspected or accused of a crime. Sometimes these rights are called "due process of law". In using these rights, a person should have the help of a lawyer. You have a right to protect against unreasonable searches and seizures. The police generally may not search you or your home, or take things you own, without a "warrant". A warrant is a paper which states, very exactly, the place to be searched and the things to be taken. Sometimes, however, the police will not need a warrant to search you or your property. If an officer sees you committing a crime, or if he has a good reason to believe you have committed a serious crime, he may arrest you and search you and the area right around you without a warrant. If you invite a police without a warrant to come into your house and he finds proof of crime, the evidence may be used against you in court. If you do not want an officer to search you or your home and he does not have a warrant, tell him that you do not give him the right to search. However, if the officer will not listen, do not try to stop him. It is dangerous to resist and it may be illegal to do so. Any evidence which a policeman gets during an unlawful search and seizure cannot be used against you. Police officers must act reasonably and fairly at all times. They should use physical force only when it is needed to arrest someone to enforce a law. They may not use physical violence to "teach someone a lesson". Question: The passage centers around _ . Options: A: the rights of citizens B: the importance of warrants C: the duty of the police D: criminal cases
A: A

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: To most of us,school means classes,teachers,schedules,grades,and tests.But for the children at Sudbury Valley School in Massachusetts,school is very different. Firstly,there are no lessons.All the children,aged between 4 and 19,do whatever they want.There are no teachers--only "staff members".The idea behind this is that you do not need to make children learn,because children want to learn anyway."You do not need to say to a three yearold,'Go explore your environment.'You can't stop them!" says Daniel Greenberg,a founder of the school."But if you make children do what you want all day,they will lose all taste for learning." At Sudbury Valley School,you will permit children to talk,read,paint,cook,work on computers,study French,play the piano,climb trees or just run around.Two boys spent three years just fishing! The other way that Sudbury Valley School is different is that the children can decide the rules.Every week,there is a school meeting where both children and staff have one vote each--even the fouryearolds.They decide the school rules,how to spend the school budget,and even which staff they want and do not want any more. When the school first opened in 1968,people said it would never work.But today,the school has 200 students,and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist. Question: What does the school believe? Options: A: Teachers cannot teach children Well. B: Children learn best when they do what they want to do. C: Learning is for adults--children should only play. D: Children should only learn about one thing at a time.
A: B
