Which of the following would be exchanged in a factor market?

A. a textbook

B. a tract of land

C. an automobile

D. a furnished home

The correct answer is certainly B. Indeed, a tract of land is raw material, productively speaking, thus it is likely to worth something when traded into the factor market (perhaps, if this tract is on good conditions, its value could be financially relevant). Among the raw material sub-market, the factor trading area contains also both the labor and the capital markets.
