A national economy cannot prosper unless every significant influence on it has been examined by that
nation's government economists.
B
Economics is weakly analogous to the physical sciences.
C

D
International trade is the primary significant variable influencing prices and wages.
E
Some government economists have been ignoring the effects of international trade on prices and wages.
