Article: Even people who don't understand English can enjoy Chaplin's films because they are mostly silent. It isn't what he says that makes us laugh. It depends upon actions which mean the same thing to people all over the world. He is _ of the art - a kind of world language. As a young man, he and his brother traveled to America in a small company of actors. Chaplin was then invited to join a new company that was making film comedies. Very soon he had made dozens of short films for this company. And it was in his second film that he wore the clothes which made his reputation - black hat, tight coat, baggy trousers, huge shoes, moustache and walking stick. He intended simply to make people laugh. But the odd make-up made him look both comic and sad. By the time he was thirty, Chaplin was the greatest, best known and best loved comedian in the world. He received thousands of dollars for each film he made. He had formed his own manner of acting. He was welcomed by excited crowds wherever he went. But he worked very hard and had few close friends. Perhaps that is why the sad side of the little tramp began to show more clearly in the films he made. The little man began to want more than food and a roof over his head. He began to want love. In one of his most famous films "The Gold Rush" a girl plays tricks on the little man. Then she begins to feel sorry for him and treats him kindly. He mistakes her pity for love. The girl in "City Lights" is blind. She thinks he is the most wonderful man she has ever met. But then she recovers her sight and sees what a foolish figure he is. This sadness gives Chaplin's films a depth of human experience which few comedians can equal. After living in America for forty years he moved to Switzerland. There he died on Christmas Day 1977. He once described himself as a citizen of famous pictures that were made during the 1920s and 1930s, the time of the silent films. But, to many people all over the world Chaplin will always be the king of comedy. Question: We may infer that films with sound probably came into being _ . Yes or no, is the answer "after the 1930s"?

No

Article: As digital technology increasingly controls the lives of young people, scientists have begun to wonder: Is the Internet good or bad for kids? "It's impossible to answer that question because the Internet is so many things," says psychologist Patricia Greenfield. "It's networked computer games and news about politics and instant messaging and e-mails to your grandmother. It can be both an educational resource and a hiding place for kidnappers." Adults have many reasons to worry about kids' Internet use. In chat rooms, for instance, it is easy to lie and kids can get trapped in dangerous situations. In searching for and visiting websites, kids can come across words and pictures that they may not be prepared for. To help prevent that situation, in 2000, the US Congress passed the Children's Internet Protection Act, which requires schools to block offensive and obscene websites. Researches have pointed out how confusing the Internet can be for children, even when they think they know how it works. To find out how much kids know about the technology, Zheng Yan, an educational professor in New York, interviews over 300 students in grades four to eight. Most of the youngest students think the Internet is simply an icon on the screen. It often isn't until 10 that kids realize that the Internet is a network of millions of computers. It takes another 2 or 3 years for them to understand that a stranger can see what they've posted. Understanding the technology helps kids understand how dangerous the web can be. It's not simply enough to block harmful websites or to limit the number of hours kids spend online. Learning about the Internet can also give young people the power to use it in beneficial ways. Question: By saying "the Internet is so many things", Patricia Greenfield means that _ . Yes or no, is the answer "computers bring advantages as well as disadvantages"?
(A).
No
