As they went along, they saw lying in the path a pair of old shoes. They supposed the shoes belonged to a poor man who was employed in a field close by, and who had nearly finished his day's word. The student turned to the professor, saying, " Let us play the man a trick: we will hide his shoes, and hide ourselves behind those bushes, and wait to see his confusion when he cannot find them". "My young friend," answered the professor, "we should never amuse ourselves at the expense of the poor. But you are rich, and may give yourself a much greater pleasure by tricking on the poor man. Put a coin into each shoe, and then we will hide ourselves and watch how the discovery affects him." The student did so, and they both placed themselves behind the bushes close by. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After he slipped his foot into one of his shoes, he felt something hard. He bent down to feel what it was, and found the coin. Astonishment and wonder were seen on his face. He fixed his eyes on the coin, turned it round, and looked at it again and again. He then looked around him on all sides, but no person was to be seen. He now put the money into his pocket, and continued to put on the other shoe; but his surprise was doubled on finding the other coin. His feelings overcame him. He fell upon his knees, looked up to heaven and cried a sincere thanksgiving, in which he spoke of his wife, sick and helpless, and his children without bread, Whom the timely help, from some unknown hand, would save from dying. The student stood there, deeply affected, and his eyes filled with tears."Now,"said the professor,"are you not much better pleased than if you had played your intended trick?" The youth replied,"You have taught me a lesson which I will never forget. Options: A wise B rich C humorous D serious Answer: A wise Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Do you suppose Darwin, one of the greatest scientists of all time, really did fools' experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish? Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important. Charles Darwin didn't settle for just thinking he knew something. And, he believed all things could be important however simple they seemed to be. Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything. But this simple experiment is important. It explains part of our present day understandings of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics. Scientist sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science. Options: A He is curious. B He is careful. C He is foolish. D He is cleverer than all the people. Answer: A He is curious. Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Rome had the Forum . London has Speaker's Corner. Now always-on-the-go New Yorkers have Liz and Bill. Liz and Bill, two college graduates in their early 20s, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street corners. And just talk. Using a 2-foot-tall sign that says, " Talk to Me," they attract conversationalists, who one evening included a mental patient, and men in business suits. They don't collect money. They don't push religion . So what's the point? " To see what happens," said Liz. " We simply enjoy life with open talk." Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return. " It started as a crazy idea." Liz said. " We were so curious about all the strangers walking by with their life stories. People will talk to us about anything: their job, their clothes, their childhood experiences, anything." Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went. Marcia had led her husband to a serious disease. "That was very heavy on my mind." Marcia said. " To be able to talk about it to total strangers was very good," she explained. To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people appeared, as well as some television cameramen and reporters. They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something the two say they'll consider before making a decision. Options: A They knew Liz and Bill very well.

Answer: D They are examples of those who talked to Liz and Bill. Question:???
