What major political challenges faced the new nations of the Western Hemisphere in the nineteenth century

That is exactly how the instructor worded it. Basically, its asking if  there was a difference between the Scientific Revolution and the  Enlightenment periods in history. If there is a difference, what is it?  If there isn’t a difference, then how are they similar? And its also  asking if both time periods only affected the elite people that had a  good education or if it affected everyone. Personally, I believe it  affected everyone, so you can write about how it affected everyone.

What major political challenges faced the new nations of the Western Hemisphere in the nineteenth century, and how well did they deal with those problems?
