Different Constituencies Elect Senators and Representatives, and They Serve Terms

Different constituencies elect senators and representatives, and they serve terms that are different in length, because the Constitution's framers:

A) modeled Congress on the British Parliament, which has the same differences between members of its two houses.
B) valued liberty, but feared that democratic participation could lead to a rule of the mob.
C) wanted top personnel within the new government to develop varying outlooks on governance, and wanted to allow diverse groups of people to have some influence in public policymaking.
D) did not trust legislators, given experiences with the takeover of state governments by radical interests in the postrevolutionary era.
