Each of the following could be considered an entrepreneur except

A merchant who resells silk in a Chinese market

The manager of a silk factory

A spy who enters a silk factory to steal silk-making secrets

A trader who from Rome to China to buy silk

The correct answer is except A spy who enters a silk factory to steal silk-making secrets. Aditionally, the last excerpt could also be considered a correct answer along with the previous one.

Explanation:

An entrepreneur is any person who establishes a business for the prospect of financial growth. A spy would not qualify as an entrepreneur because the activity of stealing, unlike the activity of selling, managing and trading, is not only illegal but also alien to the concept of entrepreneurship. In the case of the last one, the mere act of buying goods from different nations does not make the buyer-traveler an entrepreneur, unless he/she uses said goods to obtain more profits.
