Article: Recently,CCTV journalists have approached pedestrians with their cameras,held a microphone to their mouth and asked a simple question :"Are you happy?" The question has caught many interviewees off guard.Even Mo Yan who recently won a Nobel Prize,responded by saying:"I don't know". While the question has become a buzz phrase and the Internet plays host to heated discussions,we ask:What exactly is happiness ?And how do you measure it? In the 1776 US Declaration of Independence,Thomas Jefferson set in writing the people's unalienable right to"Life,Liberty and the pursuit of Happiness".Last year,235 years on,China's Premier Wen Jiabao told the nation:"Everything we do is aimed at letting people live more happily."At last year's National People's Congress,officials agreed that increasing happiness would be a top target for the 12thfive-year plan. US psychologist Ed Diener, author of Happiness:Unlocking the Mysteries of Psychological Wealth describes happiness as "a combination of life satisfaction and having more positive than negative emotions",according to US broadcasting network PBS.This may sound straight forward enough,but it still doesn't explain what determines people's happiness. Many argue that happiness is _ and that there is no single source.It also means different things to different people.For some,happiness can be as simple as having enough cash. Researchers believe happiness can be separated into two types:daily experiences of hedonic well-being;and evaluative well-being, the way people think about their lives as a whole.The former refers to the quality of living,whereas the latter is about overall happiness,including life gods and achievement.Happiness can cross both dimensions.

Read the following article and select the best answer. Article: Louis Braille, Alphabet Maker Blind people can read. They do so by running their fingers along a line of raised points or dots on paper. Of course, they first have to learn the code. Here are some examples of it. One dot stands for the letter "A." Two dots side by side mean "C." Four dots arranged to look like a box (: :) stand for the letter "G." By placing the dots in special patterns, all the letters of the alphabet can be formed. This code was made up by a Frenchman called Louis Braille. Though he could see at birth, he became sightless when he was only three. Braille was cutting leather in his father's shop. His knife slipped and cut his eye. Infection spread to both eyes, and he became blind. At 10, he was placed in a home for the blind. But young Louis had great talent. He became a skilled musician and soon got a job as a church organist in Paris. Because he had talent and was quick, he became a teacher at a school for the blind. While there, he heard that an army captain had sent messages to his gun crews so they could read them at night without light. His messages were in the simple form of raised dots and dashes. This was the clue Louis needed. At the age of 15, he worked out his own six-dot code. Each group of dots is called a cell. The cells are three dots high and two dots wide. For the rest of his life, Braille taught his young flock to read both written and musical works using his code. For the last 17 years of his life, Braille was ill with tuberculosis . He died at the age of 43. France honored him by placing his remains in the famous Pantheon in Paris. Question: From this passage, you can conclude that _ . - all blind people can read Braille. - sign language is more useful than Braille to the blind - most students know that Louis Braille developed the Braille alphabet. - Louis Braille wouldn't have developed the alphabet if he had not been blind.
Louis Braille wouldn't have developed the alphabet if he had not been blind.

Q: Read the following article and select the best answer. Article: There is a time when Karyn Bosnak couldn't pay a $59 bill at the grocery store. She was officially broke. She didn't have enough money to get on the subway, but she looked rich. She was a television producer, earned $900 a week, and had a closetful of designer labels like Gucci and Louis Vuitton. But she also had a $20,221.40 credit card bill and an empty bank account. Karyn decided that it was time for a change. She built a website and simply asked people to help her out by sending her a dollar or two. On the site, Karyn honestly explained her situation. "If 20,000 people gave me just $1, I'd be home free." Amazingly, it worked. Her website was visited by more than a million people. Although most donors just gave a few dollars, one generous donor sent $1,000. She was on TV and in newspapers and magazines. She was offered a book deal and a movie contract. And of course, she was able to pay off her credit card debt. She also sold her designer clothes on eBay. In her closet, where the Gucci purse once sat, Karyn keeps all the letters that people have sent her. It's hard to understand why so many people helped a total stranger pay off her huge credit card bill. Karyn explains, "I was just honest about what happened; I didn't make up some sob story about saving the world." Her donors think it's funny and original, and view it less as a charity than as an entertainment site. Imitators have appeared all over the Internet, some with extremely selfish requests for things like a BMW or a house. Actually, Karyn was not the first person to put up a website asking strangers for money. The practice has a name: "cyber-begging." Most sites receive little traffic and even less cash. Karyn also had thousands of enemies and critics. People sent her hate mail and scolded her on websites. Karyn says she never let this anger bother her. "They are probably jealous they didn't think of it." She explains. Question: Why did so many people respond positively to Karyn's website? - They were moved by Karyn's story. - They thought it was very interesting. - They wanted to follow Karyn's steps. - They really wanted to help Karyn out.
A: They thought it was very interesting.
