Question

a political effect of the enlightenment was that
some monarchs embraced new ideas from the movement.
support for rebels fighting the french revolution decreased.
many people rejected the idea of representative government.
the constitutional monarchy in england came to an end.

Explanation:

The Enlightenment spread ideas about rational governance, individual rights, and reform. "Enlightened monarchs" (like Frederick the Great of Prussia) adopted some of these ideas to modernize their states. The other options are incorrect: the Enlightenment inspired support for revolutionary ideals (increasing, not decreasing, backing for rebels in the French Revolution), it promoted representative government rather than leading people to reject it, and England's constitutional monarchy endured and was even influenced by Enlightenment ideas rather than ending.

Answer:

some monarchs embraced new ideas from the movement.
