The French and Indian war was a very costly war for Britain. The British decided to place the Stamp Act (tax on all paper goods) upon the colonies creating friction between the colonies and Britain. People in the colonies used mob violence against British officials in order for the British to repeal the Stamp Act, which it later was, but things only continued with more taxes some years later.
The French who had direct contact with the Americans were able to successfully implement Enlightenment ideas into a new political system. The National Assembly in France even used the American Declaration of Independence as a model when drafting the Declaration of the Rights of Man and the Citizen in 1789
The correct answer is 1) Soviet influences spread across Eastern Europe sharply during and after World War II.
It is clear that socialism in the eastern part of Europe became much more popular and at the time seen as an ideological system victorious over extreme right national socialism (under the flags of Nazi Germany, Italy). In so, the intrinsic dynamic of Soviet socialism was another form of conquest. Soviet influences expanded regaining the territories that were previously invaded by Germany or other powers (in the case of Baltic states). The reasons were not only based the military results by that time (1945-1948) but by the notion that socialism was a new and more efficient way of settling issues in the European and capitalist world, thereby causing the empathy from some neighbour states and also expanding with the introduction of "puppet states" loyal to the Soviet Union.
Examples of this were: the government created in Poland, Checoslovakia or some other socialist republics.
