In the 1700s, an effect of the enlightenment was
1.a rise in support for representative government.
2.the creation of new protestant churches across europe.
3.an increase in new scientific discoveries and methods.
4.the return to classical ideas such as humanism and realism.

The correct answer is: "a rise in support for representative government."

The Enlightment philosophers, such as Locke, Monstequieu or Rosseau,  developed ideas that challenged, and ended up derrocating, the power structures of the Old Regime.

They promoted democratic principles, such as the definitions of bills of citizens' rights, social contract (citizens electing political representatives to create goverment through suffrage, in opposition to the prevailing absolute monarchies), and the division of the powers of the state in order to avoid excessive power accumulation in certain sectors, and risks of authoritarism.

All these ideas challenged the status quo, and gave rise to many revolutions in Europe, being the French Revolution the most remarkable one, and also has an effect overseas, as it influenced and triggered the American Revolution too.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
