The nineteenth century geographer E. G. Ravenstein noted that most migration involves . a. long-term relocation between neighboring countries b. short-distance relocations within countries c. long-term relocations within countries d. long-distance relocations within countries e. short-distance relocations between neighboring countries

Explanation:

E.G. Ravenstein has established a series of migration laws which determine the reason and the attitude towards migration of people from one place to the other.

In his findings, he noted that most migration involves short-distance relocations within countries. He noted that native migrants of a country is less likely to occur than the native migrants of a village migrating into towns or cities. Native rural migrants tends to migrate to towns and cities more than native country migrants migrating to another country or to a long distance.

Therefore, people migrate for economic prosperity to short distance urban places within the country instead of migrating into another country or long distance places.

social contract theory basically says that all individuals are born equal, and provided a god given right to consent to be governed. american government is based of this

thomas hobbes and john locke said that we are selfish, individualistic, and constantly at war with each other, therefore we need to be controlled. 

government is defined as the legitimate use of force to control human behavior within territorial boundaries, here comes in hobbes and locke.

hobbes takes the part about controlling human behavior. while locke takes the part of legitimate use of force, since force is not legitimate unless there is consent of the people. 

there are basically 3 goals of the government: 1) maintain order by protecting life and property. 2) providing public goods, those which are typically not provided by the public sector, such as roads and education. 3) promote equality be it political, opportunist or outcome equality.
