【正确答案】：The most dangerous part of the civil rights movement was the campaign to win voting rights for black Americans. The 15th Amendment to the Constitution said a citizen could not be denied the right to vote because of race or color. Several Southern states, however, passed laws to try to deny voting rights to blacks for other reasons.
Martin Luther King and his supporters demonstrated to demand new legislation to guarantee the right to vote. They held protests in the state of Alabama. In the city of Birmingham, the chief law officer ordered his men to fight the protesters with high-pressure water hoses and fierce dogs. People throughout the country watched the demonstration on television. The sight of children being beaten by policemen and bitten by dogs awakened many citizens to the civil rights struggle. Federal negotiators reached a compromise. The compromise was, in fact, a victory for the protesters. They promised to stop their demonstrations. In exchange, they would be permitted to vote.
