4. The best definition of the COLD WAR is. a cooperation between the world super-powers
b)world acceptance of communism
c)tension and hostility between the super-powers
d)armed conflict between the super-powers

C

Explanation:

D is a tough one to get rid of. There wasn't armed conflict between the superpowers, but there were proxy wars. Egypt was armed by the Soviet Union and Israel by the United States. It was sort of like participating in a football match.  You get rid of D only by stating that the conflict was not direct.

The superpowers did not have a policy of cooperation. A is utterly incorrect.

There was no acceptance of Communism. 2 wars (Korean Vietnam) were fought to contain communism.  B is wrong

C is the correct answer.

the right answer is the third one: turnpikes went short distances to connect markets. turnpikes, also known as toll roads, were very important for trade and transportation (of people, goods and products) in the 19th century, coinciding with the expansion towards the west. they contributed significantly to the economic development of the united states.
