Question: Article: Rock and roll music developed in the United States in the early nineteen-fifties. It was based on the music called rhythm and blues that was performed by African American musicians. Early rock and roll singers developed their own kinds of music. Elvis Presley, Chuck Berry, the Beach Boys, and Bob Dylan were the most popular rock and roll musicians in the early 1960's. All were American. Then, in 1964, a new rock and roll group from England invaded America: the Beatles. Some people say the Beatles' music shook America like an earthquake. The Beatles changed rock and roll forever. Their early songs were influenced by American rock and roll musicians, including Chuck Berry. But the Beatles looked different and sounded different from any musical group before them. The Beatles released their first album in the United States in 1964, when all of the top five records in America were by the Beatles. In 1967, they released an album called "Sergeant Pepper's Lonely Hearts Club Band." It was one of the first "concept" albums. That is, all the songs were linked by a common story or idea. The popularity of the Beatles led the way for more rock and roll bands from England to become popular in America. The Rolling Stones was the most important of these bands. The Rolling Stones is one of the few groups from the 1960's that is still performing and recording today. In 1965, the group recorded one of its most famous songs, "Satisfaction". The musical instrument most linked to rock and roll is the guitar. Experts say Jimi Hendrix was one of the most influential guitar players in rock and roll during the late 1960's. His "Purple Haze" was liked by many people. By the 1970's, rock and roll music became known as rock music. It expanded into many new forms. For example, there was country rock, hard rock, acid rock, and heavy metal rock. Punk rock, jazz rock, and glitter rock. In the middle 1970's, experts say rock music regained some of the energy of early rock and roll. Bruce Springsteen and the E Street Band became popular with their album "Born to Run". Springsteen's music was like the lively rock and roll music of the early nineteen-sixties. Many of his songs were about social issues. He sang about the effects of unemployment and the war in Vietnam.

Question: Article: Why do people run? That is, why do thousands get up early and put their knees and ankles and hearts and lungs through the hell of 10,000 meters on the roads? For those who stick with it and are lucky, they get into another world: a state of physical and mental grace reached when their blood is racing through every vein . And in Austin, those who long to get better, even when they know it's impossible, hang on Gilbert's every word. Gilbert's methods are simple. It's all about form: how the arms move and the feet land. He pushes his students hard. When they feel like they're about to die, they look at Gilbert's scars -- the burns along his right arm, and then to his right leg, where the flames ate down to the bone. Whatever they feel, how bad, really, could it be? "He gets people to believe in themselves," says Lisa Spenner, one of the _ , who are crazy about Gilbert. "He treats everyone like they're amazing." If Gilbert is their savior, they are his saviors too. "Eventually, I realized I had to help people. When I help people, I feel good," he says. Gilbert's right leg was so badly burnt that the knee was stuck at a 90-degree angle. The doctor said it would take six months to heal. Frustrated, Gilbert got on a bike. The biking led to walking, which finally led to running a year after he had been left to die. In truth, runners don't race other runners. They race against themselves to conquer their wills. So Gilbert spent the spring and summer of 2007 trying to do that, racing men faster than he is, knowing it would make him better. Gilbert's students, of course, keep rooting for him, though sometimes they wonder, "How much better can he get?" After all, they see him as more than just a runner and a coach. He's a flesh-and-blood symbol: the daily struggle to show what you're made of.
Question: What do we learn about Gilbert after reading the passage?
Options: (A) He used to work as a fireman. (B) He has determination and strong will-power. (C) He learnt running from a coach. (D) He was advised to ride a bike when he was badly burnt.

Answer: B

Question: Article: In modern society there is a great deal of argument about competition . Some value it highly , believing that it is responsible for social progress and prosperity . Others say that competition is bad ; that it sets one person against another ; that it leads to unfriendly relationship between people . I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills . For them, playing well and winning are often life-and-death affairs. In their single-minded pursuit ( )of success , the development of many other human qualities is sadly forgotten . However ,while some seem to be lost in the desire to succeed , others take an opposite attitude .In a culture which values only the winner and pays no attention to the ordinary players , they strongly blame competition . Among _ are youngsters who have suffered under competitive pressures from their parents or society . Teaching these young people . I often observe in them a desire to fail . They seem to seek failure by not trying to win or achieve success . By not trying , they always have an excuse : "I may have lost . but it doesn't matter because I really didn't try . "What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot . Such a loss would be a measure of their worth . Clearly, this belief is the same as that of the true competitors who try to prove themselves . Both are based on the mistaken belief that one's self-respect relies on how well one performs in comparison with others . Both are afraid of not being valued . Only as this basic and often troublesome fear begins to dissolve can we discover a new meaning in competition .
