b. Passage of the Civil Rights Act.

Explanation:

The passage of the Civil Rights Act did not occur during the 1950s. It is also called the Civil Rights Act of 1964 because that is when it was actually passed. Sputnik launched in 1957, Brown v. Board of education was 1954, and "Leave it to Beaver" began in 1957.

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
