Final answer:
The incorrect statement when comparing the Senate to the House of Representatives is that senators are more likely to be policy specialists than representatives, which is the opposite of the actual situation.
Step-by-step explanation:
The statement "senators are more likely to be policy specialists than are representatives" (Option D) is incorrect when comparing the Senate and the House of Representatives. In fact, House members, due to their smaller constituencies and committee focus, tend to have the opportunity to become more specialized in particular policy areas. In contrast, Senators, because of their broader constituent base and multiple committee assignments, often deal with a wider range of issues and may not have the same level of specialization in policy as their counterparts in the House.
