Consider the following choices. which one of the following choices is correct? a. recessions lasted for a shorter period of time in the first half of the twentieth century than in the second half. b. expansions have become shorter in the second half of the twentieth century compared to the first half. c. recessions were more severe and lasted longer in the first half of the twentieth century and became shorter and milder in the second half. d. both expansions and recession last for about the same period of time in the second half of the twentieth century.

C. Recessions were more severe and lasted longer int he first half of the twentieth century and became shorter and milder in the second half

Explanation:

recessions in the late 20th century were only half as severe as those in the late 19th century for example, even the average growth rate was similar in both periods. Recessions in the 90s prove to be milder than those in the 70s or 80s. The duration of the recoveries is not significant related to the duration or severity of the preceding recessions not impliying a slow recovery for recent mild recessions
