A turning point usually introduces new people, ideas, and technology which results in different forms of government change in idea and even rebellions. So it can be thought of as a revolution because new things are showing up and change is happening.
Because the US had a great geographical location which shileded them from immediate contact with any military force. This was one thing, another thing was that they were lending money to the different European nations which they had to return after some time.

The correct answer is the catholic church.
After Rome's fall, the people of Europe turned to catholic church for stability and guidance.
It is during this fall that catholic churches continued to grow because,
1. Christianity was being proclaimed for the religion of masses.
2. The churches were organized socially, economically, and politically.
Roman empire split and Theodosius were the events which made christianity grew rapidly. Some of the reasons for the fall of Rome included,
1. Invasion by Barbarian tribes.
2. Overreliance on slave labour and economic troubles.
3. The rise of eastern empire.
Hope this helps :)
