Example Input: Article: Throughout history there have always been people who can make other people laugh. Early clowns often both annoyed and delighted listeners with their comments and songs. They were not the silent performers seen in today's circus rings. Clowns _ when the big three-ring circuses made it impossible for the audience to hear them. Circus clowns give performances in various ways. Walk-around clowns use an animal or something, like a huge rubber hammer, as part of their performance. A carpet clown moves around, talking with the audience and performing while the acts change in the rings. Then there are acrobatic clowns, riding clowns, juggling clowns and others. Everything a clown does looks easy, but it is not. Making people laugh can be hard work. Clowns must be in good physical condition to prevent injuries. Each funny move is carefully timed and well-rehearsed . Most clowns have also been trained as acrobats, jugglers or aerial artists, and many include such skills into their acts. Generally, there are three types of circus clowns--whiteface, auguste and character. Each has a special makeup and clothes. Each has a typical act as well. The neat whiteface is usually a strict, in-charge character who sets up the punch line (the point of a joke) with a partner who is typically an auguste. His facial makeup is neatly detailed in red or black, and his clothes look so loose with a ruffle around the neck. Old circus stories have it that the auguste clown got his name from a German nickname for someone who is clumsy, acting in a careless and stupid way. The auguste wears light-coloured makeup, but white is used around the mouth and eyes, and there's a big red nose. This clown performs a great deal of humour. An oversized suit or baggy trousers allow freedom of movement for all the clumsy acts. He also wears big shoes. Character clowns perform as different characters--cowboys, grandmothers or concert conductors. The most famous character clown, however, is the tramp . Tramps wear different styles of makeup and torn clothes. Some tramp clowns are happy-go-lucky. Others are extremely sad. Still others act like gentlemen who just happen to be out of money.

Example Output: B

Example Input: Article: What do you remember about your childhood? I have good memories of exploring the fields near my house and riding my bike around the park. Today, children don't spend enough time in the fresh air. Many of them fix their eyes on a screen either on a computer, or a TV ---they seem to be living in a _ world. They have lost touch with nature. Now 400 organizations in the UK are encouraging children to have some "wild time". They want kids to exchange at least 30 minutes of watching TV or playing computer games for time playing outside. The simple pleasures of exploring and discovering nature help children to learn and keep fit too. Andy Simpson, who is part of the campaign , says: "An extra 30 minutes of wild time every day for all under 12-year-olds in the UK would be the equivalent of just three months of their childhood spent outdoors." Even if the kids live in a city, they can go on adventures in the garden or the park. However, children often need a helping hand from Mum and Dad. They need to be shown what to do and where to go. So despite the complex world that young people grow up in now, it seems that going back to basics and experiencing "nature's playground " is what modern children need. Andy Simpson adds: "We want parents to see what this magical "playground" does for their kids' development , independence and creativity , by giving wild time a go " . David Bond from Project Wild Thing says, "We need to make more space for wild time in children's daily routine, freeing this generation of kids to have the sort of experiences that many of us took for granted. "
Question: What does the author think about the present kids?
Options: (A) They depend on their parents too much. (B) They're eager to play with their parents. (C) They spend too much time playing outside. (D) They don't get close to nature.
Example Output: D

Example Input: Article: Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death. Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce. Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild.
Question: How much bamboo does a panda eat every year?
Options: (A) Nearly 3 tons (B) Nearly 2 tons (C) Almost 1 ton (D) A half ton
Example Output:
B
