Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: People often hear each others' voices without ever seeing the faces they belong to. "Nowadays we are talking away on the phone without meeting people," says Seung-Jae Moon. And from business conference calls to chat lines, people often imagine they would recognize the speaker if they saw him or her. Seung-Jae Moon, a linguist of Korea found that, under certain conditions, they're actually right. Moon decided to see just how close those mental pictures match up with reality and if there was any relation to how people speak rather than what they are saying. He recorded 16 Koreans, half men and half women, reading the same passage, and took a full-body photo and head shot of each speaker. Then he played the tapes for 361 Koreans and 173 Americans who did not speak Korean and asked his subjects to match up voice and picture. The Korean participants viewing full-body photos were quite perceptive. A majority linked 6 of the 8 women to the correct voice and did so for 5 of the 8 men. With the Korean group shown only faces, accuracy plummeted, but more than 20 percent of the subjects selected the same incorrect picture. The Americans showed no accuracy in matching the foreign voices to photos, but they too were consistent in their errors. That disconnection reveals conflicting ideas of physical and vocal beauty. Moon asked people to pick a favorite face and voice. Seventy percent of the Koreans picked one voice, but there was no agreement on a face. Americans didn' t agree on either count. And over 65 percent of both Koreans and Americans did not match their favorite face with their favorite voice. Moon hopes to use software to break voices into components like pitch and hoarseness to narrow down which elements trigger certain mental pictures. "If we can map which characteristics of the voice triggers what kind of linage, and it doesn't matter whether that image is the right or wrong one of the actual speaker, then we can create an image through voice,' he says. That capacity could help to create computer-synthesized... Options: A Less than 65 B Less than 35 C Over 65 D About 20 Answer: B Less than 35 Question:

The answer is:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Miss sending letters? Try Lettrs! This new service brings back the art of letter writing by marrying it to the Internet. Lettrs, a new site, is attempting to bring back the old-fashioned idea of letter writing by providing a space that feels a little bit like a writing desk. Of course, there'll be purists who say that to truly enjoy letter writing you must do it on fancy letter paper and envelope in the mail is part of the fun. And if you're into that sort of thing, go for it. But I can't be the only one who is now so much faster at typing that writing by hand is painfully slow. Nor can I be the only one who likes to write on a whim when I'm going to be on a crowded train or airplane, both of which are situations where writing on the computer is far easier. The site tries, pretty seriously, to approximate what it's like to have your very own writing desk and paper to choose from (which comes in various prints and colors) as well as corresponding types of prints and cursive writing that come out on your screen as you write. There's also a "desk drawer" for letters you've already sent, a "fridge" to post letters publicly, a "kitchen counter" for letters you have just received, and "shoebox" to store your letters in. And if you need inspiration there are even old-style letters that are great examples of the kind of correspondence people used to send. Lettrs is such a great idea, because you get the best parts of communicating online (typing rather than writing, the speed, no lost mail, and it's free! ) with the nice parts of a letter-the sense of sitting down to write, quietly, to one person in a meaningful way. Who would you write to? Options: A To advise readers to use Lettrs. B To tell readers how to write letters. C To persuade readers to write letters. D To show the advantage of the Internet. Answer: A To advise readers to use Lettrs. Question:???
output answer: What is the main purpose of the author writing the text?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: They don't quite know how to cope with all the dam trouble they've got down in Hampden, Maine. And according to town manager Leslie Stanley, it doesn't look as if things will improve any in the immediate future. "We've got a real annoying problem on our hands," he says. The annoyance began in late May. About three miles outside of town a group of beavers built a dam near the mouth of a culvert that carries a stream under Canaan Road. Some 50 feet of roadway and several hundred feet of land on each side of the culvert were flooded. Stanley sent a road crew out to level the dam. The beavers rebuilt it. The crew tore it apart again. In fact, they tore it apart for ten mornings-and for ten straight nights the beavers rebuilt it. On the eleventh day, the foreman tossed the problem back to the town manager. He, in turn, tossed it on to the local game warden . The warden, absorbed in beaver knowledge, moved quietly and carefully out one night and placed a petrol-soaked bag over the dam. (Any beaver expert will tell you the creatures just can't tolerate petrol smell.) In the morning the bag was found artistically woven into the dam. The warden set out three steel traps that night. In the morning one was empty. The other two had been stolen by the beavers and used to strengthen the dam. The warden, cursing the state law against hunting beavers with firearms, got his traps back and set them out again and again. And every night the beavers stole them. Town manager Stanley enlisted additional troops. He telephoned his police chief. Those beavers were breaking a state law against blocking up a natural watercourse. "Why aren't you out there to _ the law?" Stanley asked. "You're the police chief. So remove them. Arrest them. Do something." Three mornings later, the police chief proudly announced the end of the dam. At 2:00 A.M., he said, he and a licensed dynamiter had blown it to small pieces. Stanley said he'd believe it when he saw it. They drove out to the culvert and found a new dam already half-built. They... Options: A The beavers seem to be stubborn about building dams. B The beavers are allowed to be killed when causing trouble. C The beavers can't adapt themselves to living in wilderness. D The beavers finally returned to the culvert with their young.
