President eisenhower's words of warning in his farewell address foreshadowed what american era? a) korean war b) vietnam war c) civil rights d) watergate scandal

The correct answer is B) Vietnam War.

Letter A is incorrect because the Korean War happened during the early 1950's when Eisenhower was president so this cannot be right.

Letter C is incorrect because the Civil rights movement was already happening in places like Alabama, Arkansas, etc.

Letter D is incorrect because the passage has nothing to do with the expansion/abuse of power by the executive branch. Rather, this passage warns about the development of the US as a military industrial complex.
