How long did the great depression last?
a. until world war i
b. until 1930
c. until world war ii
d. until 1950

The correct answer is - C. until World War II.

The Great Depression lasted for 12 years, from 1929 until 1941. The economy started to recover from 1939, but since the unemployment was still very high, it has officially ended two years later, when the unemployment levels got an acceptable percentage.

The World War II started in the year of 1939, so it can be said that the US economy started to recuperate when the World War II started, and the Great Depression officially ended during the World War II.
