Which of the following is the most significant factor that predicts the location of human inhabitance? a. year-round moderate temperatures b. proximity to coastal areas c. availability of arable land d. proximity to trade routes

C. availability of arable land.

Explanation:

This is the most important factor when predicting the location of human inhabitance. Throughout history, the most important factor when dealing with the location of human settlements has been the availability of arable land. This is because arable land is necessary in order to sustain a large population. Settlements that are not located in fertile land can still exist, but they generally remain small. Evidence of this can be found by looking at the settlement patterns of ancient civilizations.

nothing certain is known about what happened, but it seems that the country declined gradually, perhaps due to bad government, or, more likely, due to a series of bad harvests, which resulted in widespread and recurrent famine.
