The Electoral College was created to: prevent a single region of the country from having too much political power.

give larger cities more political power.

divide power equally between both houses of Congress.

prevent a single political party from becoming too powerful.

Explanation:

First, know that the Electoral College was not made to be a 'perfect' system. And in today's times, the Electoral College has been considered 'out of date'.

One advantage of the electoral college is that it promotes fairness from a regional perspective.

Individual votes count, but in a way that is represented by states.

This prevents 2-3 very large states from overwhelming the popular vote count so that a greater portion of the country can be represented by the government.

The disadvantage is that individual votes feel like they do not count either. In 2000 and 2016, the candidate who won the popular vote did not win the electoral college.

Therefore in my opinion your answer should be A: Prevent a single region of the country from having too much political power.
