Question

Which is not one of the five fundamental questions?

Answer 1

Economics in many cases is an exact science, but usually it is a practical one that has applications. Thus there are some practical goals that need to be answered with the use of economics and an easy to summarize form of them are the five fundamental questions of economics. 3 of the choices above are such fundamental questions; determining the way of production, the receiver of the production as well as the ways in which the economic system can change are of fundamental importance to the science of economics. The other 2 questions are: What products will be produced ? and How can we foster progress?
Choice d is a pretty important question too (that falls somewhat under a) but the fact that it mentions the government specifically makes it less general than the other propositions so it is not a fundamental question.
