PROBLEM: 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.

PROBLEM: Article: American schoolchildren often wear uniforms if they attend religious or other private schools. Most public schools do not require uniforms. But over the last ten years or so, more of them have moved in that direction, including high schools. Students may have to wear a specially purchased uniform. Or they may just have to dress alike~for example, white shirts and dark color1ed pants or skirts. Even schools that do not require uniforms generally have a dress code or other rules about what they consider acceptable. Policies commonly ban clothing that shows offensive images or words, or simply too much skin. Items like hats may be not permitted because ,for example, different color1s may be connected with violent gangs. Some parents like the idea of uniforms. They say it means they do not have to spend as much on clothing for their kids. Others, though, argue that uniforms represent an unnecessary cost There are also debates about whether uniforms or other dress policies break civil rights. Students and parents have taken legal action against school dress requirements. Just last week, a judge blocked a middle school in Napa, California, from enforcing a dress code unless families have a way out of it The American Civil Liberties Union of Northern California brought the case for the families of several students who werfe punished Most attention centered on a girl who wore socks with the Tigger character from Winnie the PooK The school said its clothing policy, including no pictures of any kind, was needed to control a growing problem with gangs. The families argued that the policy went against free speech rights as guaranteed by the United States and California constitutions. The United States Supreme Court says student expression is protected as long as it does not harm the work and discipline of a school.

PROBLEM: Article: A rocket began countdown . It was a common sound in the 1960s. But this was not just another countdown. It was the beginning of a historic event. It was the countdown of Apollo 11 -the space fligh that would carry men to the first landing on the moon. In the spaceship at the top of the rocket were three American astronauts whose names would soon be known around the world: Neil Armstrong. Edwin Aldrin and Michael Collins. Neil Armstrong was the commander of the spaceship. Edwin Aldrin was the pilot of the moon lander. The astronauts gave it the name the Eagle. Michael Collins was the pilot of the command module , Columbia. He would wait in orbit around the moon while Armstrong and Aldrin landed and explored the surface. On Earth, all activity seemed to stop. President Richard Nixon gave federal government workers the day off to watch the moon landing on television. Around the world, 500 million people watched the television report. Countless millions more listened on their radios. Armstrong and Aldrin started the lander rocket engine. It slowed the spacecraft and sent it down toward the landing place. It was in an area known as the "Sea of Tranquility ". The moon lander, controlled by a computer, dropped toward the airless surface of the moon. 140 meters from the surface, the astronauts look control of the lander from the computer. They moved the Eagle forward, away from a very rocky area that might have caused a difficult landing. It took the astronauts more than three hours to complete the preparations for leaving the lander. It was difficult - in the Eagle's small space - to get into space suits that would protect them on the moon's surface. Finally, Armstrong and Aldrin were ready. They opened the door. Armstrong went out first and moved slowly down the ladder. At 2:56 on July 20th, 1969, Neil Armstrong put his foot on the moon. "That's one small step for man,"he said, "one giant leap for mankind."
