Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: In the summer of 1978 an English man named Steven was driving his tractor through a field of wheat when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat formed a circle about six meters across . Around this circle were four smaller circles of flattened wheat. Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger--nearly 15 meters across . That same year , another English farmer discovered three circles of flattened wheat on his land--one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often. The circles are called "crop circles" because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What causes the crop circles? At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists.(In fact, in 1991, two men said they made the circles themselves, but many scientists don't believe them.) People tried to copy them: They tried to make circles exactly like the ones the farmers had found. They couldn't do it. They couldn't enter a field of wheat without leaving tracks, and they couldn't flatten the wheat without breaking it. Several times people reported seeing stranger objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things from outer space or the marks left by their spaceships. Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990 some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment... Options: A that is done by living things from outer space B that cannot be solved but found all around the world C that cannot be made clear or understood D that is discovered and copied by the farmers Answer: C that cannot be made clear or understood Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Now people who are in different parts of the world communicate easier than before. But it is a little hard to understand each other well. Some of them may not understand others' words, so it's easy to make a few mistakes. For example, an important question about eating out, is who pays for the meal. If a friend of yours suggests you have lunch with him, you might simply say something like this, "I'm afraid it will have to be some place inexpensive, as I have very little money." The other person might say, "OK. I will meet you at McDonald's." This means it is agreed that the two will go Dutch, that is, each person pays for himself. He might also say, "Oh, no. I want to take you to lunch at Johnson's", or " I want you to try the steak there. It is great." This means that the person intends to pay the bill for both of you. If you feel friendly towards this person, there is no reason why you shouldn't accept this invitation. You might simply say, "Thank you. That would be very nice." ,.
