Explanation:

The "modern era" in history was introduced by the Scientific Revolution and the Enlightenment, so from around 1500 to early 1800s.  The modern era was a movement forward to scientific thinking and searching for reasonable explanations and solutions, in contrast to the medieval era's adherence to traditions, superstitions and religious beliefs. One area where they applied reasoning and investigation to seek solutions was in regard to the organization of politics.  The rights of people to assemble for political discourse, as well as the rights of people to participate in the rule (governing) of their own societies were outgrowths of the Enlightenment emphasis.  And the French Revolution was a result of such "modern" thinking.  

So the French Revolution, an 18th century event, is the appropriate answer from the choices listed.

d. migration of french settlers into english colonies
