Line graph showing U S Defense purchases from 1946 to 1969 in billions of dollars. In 1946, purchases were 20 billion. In 1950, purchases were 2 billion.

Which of the following statements best explains this graph?

US defense spending was affected by domestic needs during these years, not world events.
US defense spending was one-half that of the Soviet Union'’s from 1946 to 1968.
US defense spending declined after World War II but increased as the Cold War heated up.
US defense spending was at its highest point in the years immediately following World War II.

Answer 1

US defense spending declined after World War II but increased as the Cold War heated up.

The graph shows a drop after 1946, then a rise in the early 1950s and mid‑1950s consistent with responses to Cold War events (e.g., the Korean War and increased tensions), so this explanation fits best. The other choices are unsupported by the trend or by outside evidence.
