input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Why is 2004 a special year? Because it is a Leap Year . What's so special about that? Well, we have a Leap Year every four years. And it has 366 days, not the usual 365. In a Leap Year, we have 29 days in February, while in a usual year we have only 28 days. Why do we have a Leap Year? We have a Leap Year so we can keep the calendar in step with the seasons. The calendar is a kind of clock for the year. But how long is a year? A calendar year is 365 days. But a true year is 365 days, 5 hours, 48 minutes and 46 seconds long. That's the time it takes the earth to go around the sun. So every four years we have one more day, and we put it at the end of February, the shortest month of a year. Then we have a Leap Year. Options: A a day B a year C a little longer D than 365 days Answer: C a little longer Question:???
output answer: It takes the earth _ to go around the sun.

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Most humans expect to receive fair treatment. A recent study shows that monkeys may feel the same way. This is the first time scientists have seen this kind of behavior in animals. Scientists chose monkeys for the research because monkeys have close relationship with each other and they also have good teamwork. Sarah Brosnan, the leader of the research, put female monkeys in pairs. The researchers trained the monkeys to exchange a small rock with them. "That may sound simple, but not very many animals are willing to give things away." Says Brosnan. When a monkey exchanged a rock with the researcher within 60 seconds, she received a reward. Usually, the reward was a piece of cucumber. The partner of each monkey who made an exchange also received a reward. Sometimes the partner got the same reward (a piece of cucumber), but other times the partner received a better reward (a grape). The researchers were surprised at how the monkey _ to the unfair treatment. When a monkey saw her partner get better treatment, she was unhappy. The monkeys did not want to continue the test or eat the cucumbers they received. Some monkeys even threw their food at the researchers. Bronson's research suggests that monkeys do not like unfair treatment. However, as Brosnan explains, "We don't know how monkeys learn to dislike being treated unfairly. But that opens up a whole new research field." Scientists will continue their research. Options: A a travel diary B a short novel C a book review D a science news report Answer: D a science news report Question:???
output answer: The text is most probably _ .

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Have you ever been stuck for hours on a hard math problem? If you sat there for some time you might eventually solve it, but scientists say that daydreaming might be a much better way to tackle difficult tasks. In fact, daydreaming has long been misunderstood. It's considered to be a bad thing and often associated with laziness. "We're harsh on ourselves if we catch ourselves mind wandering," says Professor Kalina Christoff from the University of British Columbia in Canada. But the truth is that some of the most important scientific discoveries came about because scientists allowed their minds to wander. For example, Albert Einstein began his theory of relativity when he daydreamed about riding a beam of sunlight to the edge of the universe. And now, research has shown that normal people can also improve their problems solving ability in the same way, reported The Telegraph. In a study, 145 people aged between 19 and 32 were asked to list as many unusual uses as possible for everyday objects. Some of them were given a 12-minute break while the others were not allowed any break from the task. People on the break did not simply relax--some of them were told to carry out a tiring memory task while others did an easier task. Scientists found that people who did the easier task were daydreaming a lot. They thought about personal issues in the past or in the future because their mind was at ease. After the break, all participants were asked to return once again to the task of listing unusual uses for everyday objects. It was found that daydreamers improved their performance by 40 percent, while all the other people, including those who didn't have a break and who did tiring tasks during the break, performed the same as before. "People think that when the mind wanders away, it just gets turned off--but we show the opposite," explained Christoff."A more playful attitude might allow you to call in more resources ." So when you are struggling to solve complicated problems, it might be better off if you switch to a... Options: A People's minds turned off as they daydreamed. B The group that were given hard memory tasks performed best. C People who had a break showed improvement in the task. D Daydreaming could improve people's problem-solving abilities. Answer: D Daydreaming could improve people's problem-solving abilities. Question:???
