TEXT I Rolling Stones The rock group, members Mick Jagger (1943 -) vocals, Keith Richards (1943 -) guitar, Bill Wyman (1936 -) bass, Charlie Watts (1941 -) drams, Ron Wood (1947 -) guitar, former member Brian Jones (1942 - 69) guitar, one of the longest-running and most successful popular music groups to emerge in the 1960s. They first performed together in 1962. At first, they were very much in the shadow of The Beatles, but their less boyish, more rebellious style together with their more aggressive music soon won them a large following. Although their uninhibited life styles and overtly sexual lyrics often hit the headlines, it was the excellence of their com- positions (usually by Jagger and Richard) that ensured their continuing success. Among their early hits were "The Last Time" and "Satisfaction".

TEXT B1 GAZA CITY (CNN Thursday, May 13, 2004 Posted: 8:35 AM EDT (1235 GMT))-Two Israeli helicopter attacks Thursday in Gaza’s Rafah refugee camp have killed 10 people, according to Palestinian security and medical sources.2 The strikes followed Palestinian attacks on Israeli soldiers Tuesday and Wednesday that have claimed 11 soldiers’ lives. This week, violence in Gaza has claimed the lives at least 33 Palestinians as well as the 11 soldiers.3 The fighting comes as Israeli Prime Minister Ariel Sharon works on revising his plan to withdraw military personnel and Jewish settlements from Gaza and parts of the West Bank.4 Israel Defense Forces began the Gaza operation Monday night, saying the mission was aimed at destroying workshops used by Palestinian terrorists to construct Qassam rockets.5 Israeli helicopters first attacked the camp early in the day, killing seven and wounding six others, Palestinian security sources and medical sources said. A second strike was launched around 10:30 a.m. (3:30 a.m. ET), killing three and wounding eight others, the sources said.6 Wednesday night, an Israeli missile strike in Rafah killed seven Palestinians, Palestinian medical sources said. Israel Defense Forces said the Palestinians were targeted because they were trying to hide an explosive device. The strikes on the camp followed an attack that killed five Israeli soldiers traveling in a convoy near Rafah, according to the IDF.Note:7 Sharon’s withdrawal proposal - which would unilaterally withdraw Israeli military and settlements from Gaza and some regions, but not all, of the West Bank-has been praised by President Bush but was voted down in a Likud party referendum May 2.8 The prime minister has said the withdrawal is necessary because the Palestinian Authority had failed to rein in attacks on Israelis and because the diplomatic process is in a "frozen state."9 Palestinians have criticized Israel’s new plan, charging Sharon is attempting to circumvent the negotiations called for in the road map to Middle East peace, which is supported by the United States, the United Nations, the European Union and Russia. The aim of the Gaza operation is to ______.
