Final answer:
The statement that best completes the table comparing the Senate to the House of Representatives is 'Members serve two-year terms in office.' The House members are highly responsive to their district's needs due to the frequent elections, whereas the Senate serves longer six-year terms.
Step-by-step explanation:
The statement that best completes the table comparing the Senate to the House of Representatives in regard to member terms and district representation is: Members serve two-year terms in office.
The U.S. House of Representatives is composed of members who represent specific congressional districts within each state. These representatives serve two-year terms, which makes them highly responsive to the concerns and needs of their constituents, as they must stand for re-election every two years. This frequent re-election cycle contrasts with the Senate, where Senators serve six-year terms, and are elected on a statewide basis, thus being less subject to the immediate pressures of their constituencies.
Gerrymandering does affect members of the House, as district boundaries can influence electoral outcomes. While senators are also subject to gerrymandering to a degree, it has a more direct impact on representatives due to the smaller scale of congressional districts compared to entire states.
