Read the following article and select the best answer. Article: A report brought back by most visitors to the US is how friendly, polite, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet American's friendliness and helpfulness is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of distraction, and brought news of the outside world. The tough realities of the border also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest settler agent. It was not a matter of choice for the traveler or only a charitable impulse on the part of the settlers. It reflected the hardship of daily life: if you didn't take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the exhausted traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist routes. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner, amazing." Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be understood neither as superficial nor as artificial , but as the result of a historically developed cultural tradition.

Read the following article and select the best answer. Article: Recently, a scientist did some experiments. He left a group of 4-year-olds in a room with a bell and a candy. If they rang the bell, he would come back and they could eat the candy. If, however, they didn't ring the bell and waited for him to come back on his own, they could then have two candies. In videos of the experiment, he can see the children kicking, hiding their eyes--trying to exercise self-control so they can wait and get two candies. The results are different. Some broke down and rang the bell within a minute. Others lasted 15 minutes. The children who waited longer went on to get higher SAT scores. They got into better colleges and had better adult success. The children who rang the bell quickest were more likely to have received worse teacher and parental evaluations 10 years later and were more likely to have drug problems at age 32. The experiments are worth noting because people spend a lot of time thinking about how to improve education, how to become rich. But when the result is not good, they will come back to ask " how do we get people to get the sort of self-control that leads to success? " This is to enter the world of human nature. So these experiments along with everyday experience, tell us that self-control is most important. Young people who can sit through sometimes boring classes to get a degree can work hard in order to learn a language well. They can avoid drugs and alcohol. For people without self-control skills, however, school is a series of failed ordeals . No wonder they drop out and their later life is a group of foolish ideas, such as drug use, stealing and so on. Question: How long did the scientist's experiments last according to the text? - Just 15 minutes. - Within 10 years. - Less than 14 years. - More than 28 years.
(Answer)
More than 28 years.

Read the following article and select the best answer. Article: One day Thomas Alva Edison was given a letter by his teacher. His teacher asked him to give it to his mother. Edison thought it was something nice. After he returned home, he proudly gave it to his mother, saying "My teacher let me give this letter to you." Not knowing what it was, Edison's mother opened it, and then her eyes opened wide. With tears in her eyes, she looked at her son and read out the letter aloud, "Your child is a genius. This school is too small for him and doesn't have enough good teachers to train him. Please teach him yourself." The fact was that Edison liked asking strange questions in class. His teachers thought he was mentally ill. They could no longer stand him and decided to stop him from going to school. However, Edison's mother didn't give up on her son. She taught him at home. Many years after Edison's mother died and he was already one of the greatest inventors, one day he was looking through the old family things. Suddenly he saw a piece of folded paper in the corner of a drawer. He took it and opened it up. It read, "Your son is addled (mentally ill). We won't let him come to school any more." Edison cried for hours and then he wrote in his diary, "Thomas Alva Edison was an addled child, but, by his hero mother, he becomes the genius of the century."
