Which was not a limit on post-world war i prosperity?

a.) gaps between the incomes of rich and poor
b.) seasonal unemployment
c.) assembly line jobs
d.) discrepancy in wages between men and women

The correct answer is C. Assembly line jobs.

Assembly line jobs were rather useful because they created many job opportunities. An example would be in shoe-making. Whereas you once had a single person do everything all by himself, which would consume time and money, now you had an assembly line that would employ different people for different activities and thus increasing the production and employment.
