Which statement best evaluates the impact of the 1929 stock market crash on europe?

You didn't give statement choices, but the answer I would suggest is something like this:

The Depression spread to Europe because of the United States pulling back from financial involvements elsewhere in the world.  American banks stopped investing, and demanded repayment of loans.

A key example would be the case of Germany.  After the Great War (World War I), Germany was required to pay heavy reparations payments to Britain and France.  Meanwhile, Britain and France owed repayment of funds to the United States for borrowing they had done during the war.  So the United States had been supporting Germany in the 1920s with loans.  When the USA could no longer afford to extend loan monies to Germany after the market crash of 1929, that sent Germany's economy spiraling even deeper into the Depression than was felt in the United States.

the answer is a. since they were a huge producer of cotton and wanted the most money for it.

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.
