input question: Write a multi-choice question for the following article, with the given choices and answer: Article: A public high school in the rural town of Boonsboro,Maryland,offers a special program recently. Top students in the ninth and tenth grades can attend single-sex classes for math,science,English and social studies. The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. "What we really want to do is take that top group of kids and take them to the very highest level they can achieve here,so that they're prepared for college," she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities. Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth-grade English class for boys centers on books that he believes boys find interesting. "The novels they're reading now,are very manly novels. They're novels that deal with the arrogance of man and the pride of man." One of those books,for example,is "The Call of the Wild" by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada's Klondike Gold Rush. On this day,the students are working in small groups. Vincent and Logan explain why they're drawing pictures that relate to the story. Vincent said,"The main character,Buck,gets abducted , and they send him off to the Yukon in a train. So I'm drawing part of the story where he's in the train. It gets you to _ the setting of the story and gets you to think more about what's going on in the story,the important events of the story."" Instead of just doing work sheets about it,this is a lot more fun," Logan added happily. Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. "To me,it almost seems like it's hindering your chances at developing yourself because you're more focused on 'Oh,I wish they'd shut up. Oh,what do they think of me?' instead of focusing on what's the homework... Options: A To educate. B To persuade. C To instruct. D To introduce. Answer: D To introduce. Question:???

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Koalas are found only in prefix = st1 /Australia. Even if called koala bear, this animal has nothing to do with the actual bear; it is not even a mammal , but a marsupial , like the kangaroo. Its closest living s are the wombats . A koala is about 60-80cm long and weighs 5-14kg. The name "koala" means "no drink", and refers to the koala's ability to go for days without water. Koalas get the water content they need from the eucalyptus leaves on which they feed. The koala is the only mammal with a digestive system that can feed only on eucalyptus leaves--incidentally, these leaves are highly poisonous if eaten by humans. One individual consumes about 5kg of eucalyptus leaves daily and it may never drink water! The koala is a _ mammal. They prefer to move around just after sunset, spending daytime sleeping in the fork of a tree. A koala spends sleeping 75% of its time. The eucalyptus leaves they eat are rich in fiber and poor in proteins and fats. The adult must detoxify leaves with energy expense, while fiber is hard to break down. Because of this poor diet, koalas save energy by sleeping most of the day, while their movements are very slow. Koalas only have one young per year. In summer, baby koalas are born about a month after mating. The female takes it with her mouth and places it into her poach. In 6 months, the young can get out and feed on leaves. There are probably around 2,000 to 8,000 wild koalas in Australiaat present. The extremely fine gray fur is the reason why koala has been heavily hunted in the past. Koalas are killed every year by dogs, cats, dingoes, eagles and owls. They also die of disease and accidents. Options: A To escape from natural enemies. B To save its energy. C To protect itself from the sun. D To detoxify eucalyptus leaves. Answer: B To save its energy. Question:
