Final answer:
Members of the House tend to become specialists in one or two areas while Senators deal with a wide range of issues because House members represent limited groups of citizens in specific districts and focus on the interests of their constituents. On the other hand, Senators represent the entire state and consider the impact of bills on the nation as a whole.
Step-by-step explanation:
Members of the House tend to become specialists in one or two areas because they are elected by and represent limited groups of citizens living in small geographically defined districts within each state. They base their votes on how the bill might impact the people of their local district. On the other hand, Senators are elected by and represent all voters of their state, so they consider how the bill would impact the nation as a whole. The longer six-year terms of Senators also allow them to maintain a broader appeal across their entire state.
