What gains did the civil rights movement of the 1960s win for all Americans?

Civil rights activists in the early 1960s teemed with enthusiasm. The courts and the federal government seemed to be on their side, and the movement was winning the battle for public opinion. Under the protection of federal troops, in 1962 JAMES MEREDITH became the first African American to attend the UNIVERSITY OF MISSISSIPPI.

As sit-ins and freedom rides spread across the South, African American leaders set a new, ambitious goal: a federal law banning racial discrimination in all public accommodations and in employment. In the summer of 1963, President Kennedy indicated he would support such a measure, and thousands marched on Washington to support the bill.

d. i assume the underlined word is "role." reformat if it isn't.

explanation:

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
