input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Close relationships, thought to help communication by giving speakers a common context, are actually more likely to make _ when strangers are involved, a new study suggests. Because close colleagues and friends already share so much common knowledge that they often use short, ambiguous messages which can lead to misunderstandings. "People are so used to talking with those with whom they already share a great deal of information that, when they have something really new to share, they often present it in a way that they assume the person already knows it." says study-team member Boaz Keysar. Keysar and his graduate student, Shall Wu, trained 40 pairs of undergraduate students to memorize made-up names and descriptions of strange shapes. In each pair, the "director" had to communicate the identity of one of the 24 shapes. The partner had to use the information to choose the correct shape from a set of three images on a computer monitor. Half of the partners studied only the first six shapes, while the others learned the first 18 shapes. The directors, who had memorized all the shapes, were aware of their partners' knowledge levels of the shapes. In the pairs with the most shared knowledge, the directors were more likely to rattle off shape names, compared with pairs with little knowledge overlap , in which the directors were more likely to describe the actual shapes. Not surprisingly, participants with more shared knowledge were twice as likely to ask for clarification as those with less overlap. Language itself can be confusing. "The reason all this is happening at all is that language in general is ambiguous," said Keysar. He recalls an ambiguous billboard near a stadium holding a Rolling Stones concert that night. The billboard read, "Avoid LSD tonight." (:LSD"") Hmmm? "It was about Lake Shore Drive, and I'm sure the writer of the sign didn't realize he was being ambiguous," Keysar said. "Even though miscommunication can lead to missed meetings or deadlines, people are often unaware when their language is... Options: A most people know what LSD usually refers to B local people would not misunderstand the meaning of LSD C the writer of the sign means to play jokes on those attending the concert D people sometimes ignore the limitation of shared knowledge Answer: D people sometimes ignore the limitation of shared knowledge Question:???
output answer: It can be inferred from the example of the billboard that _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Hey, mom, I want you to stop dropping me off at the airport for some trip that I am about to take and start becoming my seatmate. I want to travel with you---just you. I want to explore a new place alongside a woman who raised me, who put up with my teenager anxiety and my rebellious college years. I want to see my favorite cities with the lady who taught me basic life lessons, such as looking both ways before crossing the street, how to use a glue gun, and that the most important thing in the world is to help others. I always appreciated the vacations you planned for our family. I also remember how you watched me as I read The Great Gatsby on the balcony at midday. I wonder if you felt proud of me. These days, I am sick of traveling to places with wishy-washy friends. I want to travel with a strong woman who can see how capable I am of learning to speak French or hiking on a glacier or eating something as unpleasant-smelling fruit. Now I want you to see how much I grow up while abroad---I'm a different person, Mom. And I know you'd be different too. I know that someone has shared a similar burst of emotion while diving into Australia's Great Barrier Reef for the first time. So what do you say, Mom? Will you _ ? I want to travel with you. Let's just go---we can go anywhere in the world, just you and I. You can pick the place, and I will do the rest. Love, Katka Options: A Exploring a new place alongside her mother. B Visiting favorite cities with her mother. C Looking both ways when crossing the street. D Offering help to others when it's possible. Answer: D Offering help to others when it's possible. Question:

Answer: Which life lesson does Katka think the most valuable?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Some people can stay up all night and still get work done the next day. I'm not one of them. After a night without enough sleep, I feel bad-tempered. I have trouble remembering things. And all I want to do is go to bed. How do you feel after you've stayed up late to finish schoolwork or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes. New research suggests that a gene called "period 3" influences how well you function without sleep. The "period 3" gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you. Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of "period 3". Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers. Results showed that the people with the short form of "period 3" performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests (those with the short form of "period 3") took about 18 minutes to nod off. While people with the long "period 3" gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form. I think I must have the long form of "period 3". What about you? Options: A to tell the result of a research on sleepy gene. B to tell us the importance of plenty of sleep. C to inform the harm of lacking sleep. D to announce the sleeping rules of humans. Answer: A to tell the result of a research on sleepy gene. Question:
