While attending college, he began performing in folk clubs and coffee houses.It was also when he started his songwriting.Callier continued to record and give live concerts through the 1970s touring with some famous popular singers.His combination of fierce guitar, wise lyrics and sweet voices created a distinctive style known as jazz-folk.However, he had more success as a songwriter than as a singer when he sang his hit song The Love We Had Stays on My Mind in 1971. In 1983 he abandoned music completely to attend his 12-year-old daughter after splitting up with his wife.He got a steady job at the University of Chicago and did not touch a guitar for years.Many years later, some DJs discovered his old recordings and began to play his songs in clubs.Though Callier was unwilling to get involved in music again, Callier was eventually persuaded to come back, which brought him more applauses than he had ever experienced.

Article: Do you enjoy seeing the stars twinkling at night ? Or do you love the ocean and sea, diving and racing with lovely dolphins? With heavy burdens on their shoulders, teenagers find it hard to pull out. Even if they are free, they prefer to occupy themselves with computer games or watching TV. How to get children away from screens is a great concern for parents. Now there is some good news for those concerned parents and teachers. A campaign is being launched to encourage children to surrender 30 minutes of screen time a day to head for the great outdoors. The newly formed Wild Network - a collaboration of nearly 400 organizations - is attempting to attract youngsters away from television and computer screen and into fields, woods and parks. Organizers say it is the UK's biggest ever campaign to reconnect children with nature and outdoor play, and claim it could help improve fitness, mental alertness and general well-being. A documentary film, Project Wild Thing, will herald the launch at more than 50 cinemas across the UK from Friday. It looks at the increasingly fragile link between children and nature. Members of the network include the National Trust, RSPB, Play England and the NHS sustainable development unit. Andy Simpson, chairman of the Wild Network, said: "The tragic truth is that kids have lost touch with nature and the outdoors in just one generation. Time spent outdoors is down, roaming ranges have fallen drastically, activity levels are declining and the ability to identify common species has been lost." Suggestions of how to get more time in nature include collecting conkers , camping or snail racing, and observing autumn colour on trees. From January, the network will aim to make suggestions to politicians on how government can do more _ This is not the first time the message of less screen, more play has been brought up. Children in the 1980s were entreated to do the same by the BBC TV series Why Don't You, which somewhat confusingly called on its viewers to "switch off your TV set, and go do something less boring instead".
Question: What is the main purpose of the campaign in UK?
Options: (A) To save 30 minutes for watching TV programme each day. (B) To encourage children to play outdoors. (C) To see the documentary film, Project Wild Thing. (D) To teach students how to learn more efficiently in schools.

Article: There were times it was only schoolchildren who felt sick before they got their grades. But now teachers in Germany are scared, too, as they are being graded by their students. Many teachers are opposed to it. They don't mind being evaluated . But they are upset because the results are then being posted on the Internet and accessible to millions of Internet users. On the websitewww.spickmich.deduring the past four months students have posted evaluation of 100,000 teachers. The teachers are graded on categories such as "motivated", "good instruction", "easy examinations", or even "sexy". Many teachers think that their privacy has been violated. The creators of the website say that the students are only being offered the chance to provide teachers with some feedback about their classroom instruction. Bernd Dicks, who founded the website with three friends, says that the students are largely quite satisfied with their teachers. On a grading scale of one to six, the teachers' average grade is 2.7 and it has been improving lately. He often says the impression is that students are bullying their teachers. But there is also bullying of the students by teachers. "Teachers must also learn to live with criticism," he added. But still, the website is not totally immune from manipulation , as one teacher near the northern city of Hanover recently proved. He registered himself on the website as a student and then rated his own teaching colleagues highly. Within a few days, seven of his colleagues were listed in the top 10 ranking of Germany's best teachers.
Question: Many teachers are opposed to the website because _ .
Options: (A) their privacy has been violated (B) they are afraid of being assessed (C) their evaluations are unfair (D) the results are not satisfying
