How long is a term for a member of the House of Representatives?

What does this answer mean?

A member of the House of Representatives serves a two-year term. Article I, Section 2 of the Constitution says House members are chosen every second year by the people.

Because of this, every House seat is up for election at the same time, every two years. Under the 20th Amendment, the terms of the new members begin at noon on January 3. Short terms mean representatives face the voters often, which keeps them closely tied to public opinion, the answer to another question on the test.

There is no limit on how many terms a representative can serve. To serve, a representative must be at least 25 years old, a U.S. citizen for at least seven years, and a resident of the state they represent.

Compare the three terms: representatives serve two years, the president four, and senators six. At the interview, say "two years."
