Answer: the correct answer is B Foot-in-the-door phenomenon
Explanation:
Foot-in-the-door (FITD) phenomenon is a compliance tactic that aims at getting a person to agree to a large request by having them agree to a modest request first.
The principle involved is that a small agreement creates a bond between the requester and the requestee. Even though the requestee may only have agreed to a trivial request out of politeness, this forms a relationship which – when the requestee attempts to justify the decision to themselves – may be mistaken for a real affinity with the requester, or an interest in the subject of the request. When a future request is made, the requestee might feel obliged to act concurrently with the earlier one.
Rivers were attractive locations for the first civilizations because they provided a steady supply of drinking water and made the land fertile for growing crops. Moreover, goods and people could be transported easily, and the people in these civilizations could fish and hunt the animals that came to drink water.
