Question

why has the house of representatives grown so much faster than the senate?
representation is based on population, and the us has grown steadily.
the number of senators allowed per state has been routinely reduced.
fewer and fewer representatives have been re - elected to additional terms.
the constitution requires the number of representatives to increase each decade.

Explanation:

The House of Representatives is apportioned based on state population, which has grown steadily in the US. In contrast, each state has exactly 2 senators, a fixed number set by the Constitution that does not change with population growth. The other options are incorrect: Senate seats per state are not reduced, re-election rates do not drive size growth, and the Constitution does not mandate a mandatory increase each decade (it requires reapportionment, not a set increase).

Answer:

A. Representation is based on population, and the US has grown steadily.
