I'm taking a test and have to guess the right answer to the question after the article. Article: Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem. It seemed impossible to get the thread to run smoothly around the needle. Despite his exhaustion, Howe slept badly. He tossed and turned. Then he had a nightmare He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make a small hole in the center of the needle and have the thread run through it. This was the simple idea that finally made Howe design and build the first really practical sewing machine. Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. To appreciate the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious , but still active part digests your experiences and goes to work on the problems you have had during the day. However, the unconscious part expresses itself through its own logic and its own language.. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called "secret messages to ourselves". Question: According to the passage, Elias Howe was _ . Options: A: much more hard-working than other inventors B: the first person who solved problems while sleeping C: the first person at the time who knew the value of dreams D: the first person to design a sewing machine that really worked
D

I'm taking a test and have to guess the right answer to the question after the article. Article: Started in 1636, Harvard University is the oldest of all the many colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard. In the early years, these schools were much alike. Only young men went to college. All the students studied the same subjects, and everyone learned Latin, Greek and Hebrew. Little was known about science then, and one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers or teachers. In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could receive their training in Harvard's law school. In 1825, besides Latin and Greek, Harvard began teaching modern languages, such as French and German. Soon it began teaching American history. As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them. Today, there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with special fields of learning. There's so much to learn that one kind of school can't offer it all. Question: On the whole, the passage is about _ . Options: A: how to start a university B: the world-famous colleges in America C: how colleges have changed D: what kind of lesson each college teaches

I'm taking a test and have to guess the right answer to the question after the article. Article: Internet use appears to cause a drop in psychological health, according to a research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling. Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others. The fact that Internet use reduces time available for family and friends may explain the drop-in well-being, researchers supposed. Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives. "But it's important to remember this is not about the technology; it's about how it is used," says psychologist Christine Riley of Intel, one of the study founders. "It really points to the need for considering social factors in terms of how you design applications and services for technology." Question: Why did the results of research puzzle the researchers? Options: A: People could choose their information through Internet. B: They had expected the opposite results. C: People can communicate with others. D: They had thought Internet was much healthier.
