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

Answers from the USCIS list

Give this answer. Words in light (parentheses) are optional.

• Senate and House optional: (of Representatives)

Our explanation

The Founders disagreed about how states should be represented. So they made two parts. In the House of Representatives, states with more people have more members. In the Senate, every state has two senators.

Remember it

Congress has 2 parts: Senate (100 members) and House (435 voting members).
