Hunting and gathering societies which generate very little surplus food and material property are described by sociologists as economies.

The answer is subsistence.  The problem with this kind of living is that it is not consistent in providing for the people who depend on it.  There are times when an area is plentiful and there are times when it is not. This is the reason why eventually farmers were superior to hunters because they generated enough for their consumption.

"choosing is refusing" means individuals face an opportunity cost with each decision they make. economists state that every decision involves trade-offs. opportunity cost is the least desirable alternative given up as a result of a decision.

there are no options provided but you can choose among the following gender-neutral pronouns: zir, hir, eir, vis, tem, eir.

in the normal course of maintaining a pronoun-antecedent agreement, we could have used the words his or her but since we are also required to use gender-neutral language, we need to replace it with its equivalent gender-neutral pronoun.
