Can someone please help me in finding out the right answer from the following question. Huge idle capacity in the U.S. at the beginning of World War II made: (1) The war costless for United States. (2) U.S. living standards drop more than had all resources been completely employed. (3) Living standards nurture less than had our economy been completely employed. (4) It is possible to very much expand the production of both military and civilian goods between the year 1941 and 1945.
