An American who believes that government should not get involved in the economy, but should restrict social choices, is most likely to be a "conservative" although of course there are exceptions.
This person is more likely to be a conservative, or to support the Republican party. Conservatives tend to emphasize the role of government in regulating social behaviour. They often care about the preservation of traditional values. On the other hand, they do not believe the government should be involved in the economy, and they tend to defend the importance of personal responsibility.
The answer is B (Socialist). It would not be Private Entrepreneurs and Capitalist since they support private control of production. Socialism on the other hand believes that production should be controlled by the workers themselves.
I'm pretty sure it would be B, because the tensions between most groups are mainly to do with religious differences, especially relating to the belief of how many gods exist.
