What are the two parts of the U.S. Congress?

What does this answer mean?

The two parts of the U.S. Congress are the Senate and the House of Representatives. Together they make the federal laws.

The two parts are built differently. The Senate has 100 members, two from each state, and senators serve six-year terms. The House has 435 voting members, divided among the states by population, and representatives serve two-year terms. This design came from a compromise at the Constitutional Convention between large states, which wanted representation by population, and small states, which wanted an equal vote.

To become law, a bill must pass both the Senate and the House. Each part also has powers of its own. Bills to raise money through taxes must start in the House, and the Senate approves treaties and the president's choices for judges and other top officials.

At the interview, say "the Senate and the House of Representatives," or simply "the Senate and the House."
