Answer:
According to the early human migration patterns they moved for about two to three miles per generation.
Explanation:
First of all, we need to contextualize here to understand why humans only moved as far as three miles per generation. Now, to start I would like to point out something. Early human groups weren't a settled group of civilizations, they were nomads and collectors, in the best cases they started to develop crop farming methods but that was really unlikely. So they depended almost solely on gathering and hunting. Thus, they weren't really able to get enough resources to perform long trips. They followed animal groups to hunt them down and that was also a reason to only move in small distances. Because in that time animals had plenty of places to move in the same areas. Also because if they had enough resources in a single place there was no real reason to leave. But that changed when settlements and civilizations developed. Rivalry for resources was a major migration factor.
Answer:
The correct answer for the question: The idea of supply and demand is based on the development of:______, would be, the offering and generation of the necessary number of products that will satisfy the needs of the consumer.
Explanation:
The theory of supply and demand, presented first by Adam Smith in 1776, sought to explain how in a free market economy, the offer of goods, the demand of goods, and prices, play a role and control each other. As such, demand is probably one of the fundamental parts of the theory as it is from the consumers´ needs that a producer will both supply, and price, their product. If demands of consumers were not met by a producer, then consumers would simply turn away to other producers who can offer them what they need, in the amount needed, and for the price that is desired. This is the reason why the answer above is the correct one.
