Which statement is true?

A) President Eisenhower did not attempt to undo the legacies of the New Deal,such as Social Security and unemployment insurance.
B) There was a major tax increase in 1964.
C) A war in Vietnam and a "war on poverty" in the Johnson Administration helped to reduce the federal budget deficit.
D) None of the choices are true.

President Eisenhower did not try to repeal or weaken Social Security or unemployment insurance, which were two major pillars of the New Deal. He also expanded the scope of other New Deal programs like the minimum wage, and even proposed new initiatives like the creation of a Department of Health, Education, and Welfare. Therefore, statement A is true. Statement B is false, as the major tax increase actually occurred in 1968 under President Johnson. Statement C is also false, as the Vietnam War and the War on Poverty both contributed to significant increases in federal spending and deficits.
