Which technological development had a greater impact on the chinese empire- printing or gunpowder?

Hmm... That's honestly a tough cookie. I would say gunpowder though, because it helped them strengthen their militia, and that is a very important aspect in any sort of country or empire that wants to be respected. It also helped them develop deadlier weapons for their naval forces, which the Chinese empire was very advanced in-- think of Britain in the 1800s but long before Britain was even an idea.  Also, as it was such a deadly instrument, many other nations wanted to get hold of it, and China could get wealthy from trading it.

answer; language that can promote racial stereotypes;

the third answer is correct (c).

the laws that regulate the financing of political campaigns seek to guarantee the smoothness of funding so that there is no abuse of electoral economic power and to avoid the capture of future politicians by the donors.

this is because donor agents have their private interests that are not necessarily the same interests of the society that elected politicians must defend.

thus, interest groups should seek their interests within the legality of lobbying practices that are regulated.
