Why is gerrymandered a problem for the house of representatives but not the senate?

The correct answer is D. Gerrymandering is a problem for the House of Representatives but not the Senate because states are always represented by two senators, regardless of the size of their population.

Explanation:

Gerrymandering is a term of political science referred to a manipulation of the electoral constituencies of a territory, joining them, dividing them or associating them, in order to produce a certain effect on the electoral results. It can be used to improve or worsen the results of a particular political party or ethnic, linguistic, religious or class group. It is, therefore, a technique aimed at breaking the impartiality of a given electoral system. In technical terms, it is a case of malapportionment: the percentage of seats in a district does not match the percentage of the population of the district, which results in some districts being overrepresented and others underrepresented. This can only be done in the House of Representatives, because in this house of Congress the states are divided in districts, but not in the Senate, as senators represent the entire state.
