Which describes a difference between the duties of a house members and the duties of Senate members

The correct answer is "Senate members represent state interests while House members represent district interests."

One of the biggest differences between Senators and members of the House are the people they represent. Remember, there are two Senators per US state, no matter the size of the state. However, the number of representatives in the house for a respective state is based on its population. Larger states like California and New York have more representatives due to larger populations.

Due to the larger populations of these areas, the states are broken down into Congressional districts. These districts allow House members to bring up local matters on a national platform.
