input question: Write a multi-choice question for the following article, with the given choices and answer: Article: What will man be like in the future----in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change to the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. Options: A Man's hair is getting thinner and thinner. B Man has got stronger eyes now than he ever had. C Man has been growing taller over the past 500 years. D Man's arms and legs have become lighter and weaker. Answer: C Man has been growing taller over the past 500 years. Question:???
output answer: Which of the following serves as the evidence that man is changing?

Write a multi-choice question for the following article, with the given choices and answer: Article: A man wakes up with a big hangover the morning after attending his company's annual Summer Party. He can't even remember how he got home from the party, let alone how he got so drunk and is deathly afraid of what he may have done or said the night before to make his wife angry. The man forces his eyes open and the first things he sees are two headache tablets next to a glass of water on his table, and, next to them, a single red rose! He sits up with difficulty and sees his clothing hung on the back of his chair all clean and pressed and the rest of the house all in perfect order. Incredulous , the man takes the tablets and sees a black eye looking back at him from the bathroom mirror. Then he finds a note next to the red rose on the table, "Sweetie, breakfast is waiting for you on the stove. I left early to buy the cooking materials to make your favorite dinner tonight. I love you, darling! " The note was signed, "Your loving wife." The man then walks into the kitchen. His daughter Jessie is at the table, eating. "Jessie...what happened last night?" The man asks, with great fear. "Well, you came home around four o'clock in the morning, drunk and out of your mind. You tripped and fell onto the coffee table and broke it, and got this black eye when you crashed into the table's edge." Puzzled, the man asks Jessie, "Then why is there a rose on my table and breakfast on the stove waiting for me?" "Oh that," Jessie replies, "well, Mom pulled you into your bedroom, and when she tried to undress you, you yelled, 'Leave me alone; I'm married and I love my wife!'"

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: When people reunite with their loved ones, it's usually all extremely happy moment. But what is their most common response to seeing them again? It may seem strange,but most of the time they break down in tears. Now a group of psychologists from Yale University say they have found the reason why, and that crying tears of joy may well be the body's way of keeping emotional balance. "They seem to take place when people are overtaken by strong positive emotions, and people who do this seem to recover better from those strong emotions," Oriana Aragon, the lead researcher said. Aragon and her fellow psychologists looked at hundreds of participants' emotional responses to different things, including happy reunions and cute babies. Many participants said they would react in a negative or aggressive way to the positive things ---- to cry at happy moments and want to pinch a cute baby's face or even tell them "I want to eat you up!" But then researchers found that these people were able to calm down from strong emotions more quickly. There are many other examples of times when people respond to a positive experience with a negative emotional reaction. At an exciting concert, fans scream at their idols . People who have just had a big lottery win are often in floods of tears. "These findings advance our understanding of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together." said Aragon. Options: A The reason why people cry with tears. B Crying tears of joy helps to balance emotions. C Strong negative feelings are useful to people. D People recover slowly from strong emotions. Answer: B Crying tears of joy helps to balance emotions. Question:
