[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Many people go to school for an education. They learn languages, history, politics, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet, no one can learn everything from school. A teacher, no matter how much he knows, can not teach his students everything they want to know. The teacher's job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves. It is always more important to know how to study by oneself than to memorize some facts or a formula . It is actually quite easy to learn a certain fact in history or a formula in math. But it is very difficult to use a formula in working out a math problem. Great scientists before us didn't get everything from school. Their teachers only showed them the way. Edison didn't even finish primary school. But they were all so successful. They invented so many things for mankind. The reason for their success is that they knew how to study. They read books that were not taught at school. They would ask many questions as they read. They did thousands of experiments. They worked hard all their lives, wasting not a single moment. Above all, they knew how to use their brain. Options: A They received good education. B They were very clever. C They knew how to learn. D They learned lots of facts and formulas. Answer: C They knew how to learn. Question:

[A]: Why were many scientists so successful?

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Antifreeze is a liquid that is added to water to keep it from freezing. When water freezes and turns to ice,it expands .The force of water expanding is so great that it will break the hardest metal.Water is used in car engines to keep them cool while they run,and if this water is allowed to freeze in winter it can break the iron block of the engine.That is why antifreeze is necessary. Water freezes at 0degC;the usual kind of antifreeze will not freeze until the temperature is-40degC.A mixture of five parts of water and four parts of antifreeze will prevent freezing at-18degC;four parts of water and five parts of antifreeze reduce this to -22degC. Alcohol is a kind of good antifreeze,but when the air is running it becomes hot and the alcohol boils away,so it must be changed very often.Most people use antifreeze that does not boil away when the engine is running.There are several chemicals that do this.One of the most popular is called ethylene glycol. Options: A 0degC B -18degC C -22degC D -40degC Answer: D -40degC Question:

output: The usual kind of antifreeze freezes at _ .

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy. Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is _ . Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. As a result, they became shy. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families. You may also be shy because of where you were born. When scientists studied shyness in different countries, they found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure . In Japan, when people do not succeed, they feel bad about themselves. They blame themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends, or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less about failure and are less shy. For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversation. And don't forget---if you are shy, you are not the only one. Options: A genetics, grown--ups and birthplace B genetics, family size and birthplace C family size, grown--ups and failure D genetics, family size and freedom Answer: B genetics, family size and birthplace Question:

Answer: We can learn from the passage that _ may cause shyness.
