Explanation: In literature, Local Color means aspects of a region that is peculiar to them only. In his book, Mark Twain captures the language, customs, traditions, and manners of people, all these are examples of local Color. Other examples of local Color are fashion, artwork, accent e.t.c.

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.
