Just checking to see if I am correct on this macroeconomics question??

Question

The basic concern of economics is:

to keep business firms from losing money.

to prove that capitalism is better than socialism.

to study the choices people make.

to use unlimited resources to produce goods and services to satisfy limited wants. (I AM THINKING THAT THIS ONE IS RIGHT)

Answer 1

none of them.

economics is focused in to let to society to decide 1.- what to produce, 2.- how much produce and 3.- distribute the goods produced.

.- to keep business firms from losing money is a tool used for some economies to solve the 1 and 2 basics.

.- to prove that capitalism is better than socialism is not a topic of economists else of politics; down capitalism or socialism the three basics can be reached.

.- .to study the choices people make. is a tool used to apply 1th basic mentioned.

.- to use unlimited resources to produce goods and services to satisfy limited wants is not an economics principle because the resources are not unlimited.

Economics can not concentrate in one or two basics showed. it studies the three basics mentioned.

Answer 2

As most "resources" are limited in some way or another I believe that the "basic concern of economics is"..."to study the choices that people make."

Answer 3

Macroeconomics identifies the matrix of aggregate information relative to human and material resources.  Land, Labor, and Wealth on the grand scale is the pursuit of Macroeconomics.

Macroeconomics is a tool for business analysis.

Both capitalist and socialist utilize political economic science.

Finite and infinite resources are factors to examine and study.
