c. surplus production served as a kind of capital, or wealth that stimulated new kinds of socioeconomic interactions.

Question 2
Some researchers argue that human population growth initiated the agricultural response at the end of the last Ice Age; others see it happening the other way around. But there's no question that
a. population size and density both tended to decrease as farming produced smaller and less predictable yields.
b. population size and density both tended to increase as farming produced larger and more predictable yields.
c. population size tended to increase and density decrease as farming produced larger and more predictable yields.
d. population size tended to decrease and density increase as farming produced larger and more predictable yields.
e. population size and density both tended to increase as farming produced larger but less predictable yields.
