Question

one lasting effect of the age of revolutions was that
liberals were successful in all nations and remain an active political force.
monarchs were inspired to be more democratic and granted rights to citizens.
some monarchs were successfully overturned, allowing for the growth of democracy.
no monarchs were overturned in europe and many nations experienced a rain of tyranny.

Explanation:

The Age of Revolutions (e.g., American Revolution, French Revolution) saw the overthrow of certain monarchies (e.g., French monarchy in 1792). These events cleared paths for democratic systems to develop, making this option the most accurate lasting effect. Other options are incorrect: liberals were not successful in all nations; not all monarchs became more democratic; and some European monarchs were overturned, so the claim of no overturns is false.

Answer:

C. some monarchs were successfully overturned, allowing for the growth of democracy.
