Why does each state have two senators?

What does this answer mean?

Each state has two senators so that every state has equal representation in the Senate, which especially protects small states. USCIS accepts two answers: equal representation (for small states), or the Great Compromise, also called the Connecticut Compromise.

At the Constitutional Convention in 1787, the states disagreed about how Congress should be built. Large states wanted the number of lawmakers to depend on population, which would give them more power. Small states wanted every state to have the same say.

The delegates settled on a compromise. Congress would have two parts: the House of Representatives, where seats depend on population, and the Senate, where every state has two members. This deal is known as the Great Compromise, or the Connecticut Compromise.

The result still shapes Congress today. A state with a small population has the same two votes in the Senate as the largest state, while its voice in the House depends on its size.

At the interview, either answer works. "Equal representation" is short and easy to remember.
