Question: Article: A teddy bear from Cumbria is launching into space to raise cash for charity . Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation legend Burt Rutan's Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off in aid of the North Air Ambulance Appeal . Spaceship One is the world's first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said "flying officer" Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since. He said, "Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed--we just hope he does not burn up on re-entry to Earth." GNAAS, which needs charitable donations of more than PS2m a year, has three air ambulances . Peter Bond, spokesman for the Royal Astronomical Society, said Terence's safety was not guaranteed. He said, "This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved." Since May, Terence has spent time with members of 100 Squadron based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes. Spaceship One will fly 100km (62 miles) above the Earth's surface, just breaking through the planet's atmosphere. If it repeats the feat inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.
Question: Terence is _ .
Options: (A) a real bear living in England (B) an experienced astronaut (C) an air force officer (D) a toy bear

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.
