Answer - Acid Rain

Explanation:

Scientific discoveries have it that escarpment is that area of the earth where elevation seems to change suddenly. It is sometimes refers to the bottom of a cliff or a steep slope.

Acid rain is that rain or any other form of precipitation that has elevated levels of hydrogen ions. This acidic rain is usually caused by the release of gases such as nitrogen oxide and sulphur dioxide into the atmosphere, which reacts with water molecules of the atmosphere to form acids.

A small portion of these gases come from volcanoes and other natural sources while the major amount of the gases come from the burning of fossilized fuels.

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.
