Input: Consider 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.

Options: (A) became silent to avoid annoying people (B) began to perform silently because of larger audiences (C) realized audience members often spoke another language (D) discovered that three-ring circuses were becoming more popular

Output: B

Input: Consider Input: Article: As a school teacher, Inderjit Khurana used to take the train to work. And one day, at the station, she saw dozens of children who spent their days begging from train passengers rather than going to school. She learned that it was not a rare problem and that millions of children in India lived on the streets. Realizing that these children would never be able to escape poor life and homelessness without education, and that it would be impossible to send these children to school, Inderjit decided to create a model program---taking the school to the most out- of-school children. Khurana's train platform schools aim to provide a creative school form and give children the basic levels of education. Her last goals reach far beyond the 20 platform schools she and her colleagues have created in India's Bhubaneswar region. She is determined that her program will become a model for changing the lives of the poorest children throughout India and the world. Khurana founded the Ruchika Social Service Organization(RSSO) in 1985. The teachers gather the children together between the stops of the train for reading, writing, maths and history taught through songs and other teaching tools. Khurana recently comes to realize that the education of these children is impossible when the most basic needs of their families are not being met. So she also provides food and medicine for their families. Khurana insists that every child have the right to an education and that if a child cannot come to the school, then the school must come to him or her.
Question: Khurana's final aim is to _ .
Options: (A) make the poorest children's lives better (B) put an end to the problem of children's dropout (C) attract more students to her platform schools (D) set up 20 platform schools throughout India

Output: A

Input: Consider Input: Article: We can make mistakes at any age.Some mistakes we make are about money.But most mistakes are about people.One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad. Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning.And if we don't really listen, we miss the feeling behind the words.Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You are a lucky guy", that's being friendly.But if he says "a lucky dog", there's a bit of envy in those words.Maybe he doesn't see it himself.But he puts you down a little if he brings in the "dog".What he may be saying is that he doesn't think you deserve your luck. "Just think of all the things you have to be thankful for" is another noise that says one thing and means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important.It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night. How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking.Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake. Therefore, when you hear someone saying, please try to know what he really means.Don't just listen to what he says with your ears but feel the words he uses with your head.In this way you may make fewer mistakes.

Options: (A) how to avoid mistakes about money and friends (B) what to do when you listen to others talking (C) how to avoid mistakes in understanding what people tell you (D) why you keep people friendly without trusting them
