Before money was invented, how were goods and services exchanged?

a. kings evenly distributed items.

b. merchants and customers bartered.

c. individuals were self-sufficient.

d. priests evenly distributed items.

Let's look at the various options and see which one makes sense. a. kings evenly distributed items. * This option would assume that every place prior to money being invented had a king. That doesn't make sense, so this option is wrong. b. merchants and customers bartered. * This option works. I have X and want Y, you have Y and want X. Let's trade. Or perhaps you have Y, but want Z. But that 3rd person over there is willing to trade Z for X, so between the 3 of us, we can each get what we want by trading what we have an excess of. Rather cumbersome, but it worked prior to the development of money. This is the correct choice. c. individuals were self-sufficient. * No man is an island unto himself. No one have every skill they need to live. So this is a bad choice. d. priests evenly distributed items. * The priests would have liked this option, but it too is a bad choice.
