Answer:
A. prevent senators from being overly influenced by public opinion.
Step-by-step explanation:
The Constitution set up the two places of Congress, with the Senate including two individuals from each state, designated to six-year terms, and the House of Representatives made up of shifting individuals from each state, in view of population, chose to two-year terms.
The six-year Senate term should make a balance stable enough to be verified in their situation without having to face re-election every two years and to prevent senators from being overly influenced by public opinion.
