If members of One chamber of Congress cannot pass a bill by a majority vote what happens?

If members of one chamber of Congress cannot pass a bill by a majority vote, the bill fails to advance in that chamber. It may be reintroduced later or modified for reconsideration. If the bill had been passed by the other chamber, it will not become law without approval from both chambers. Additionally, the legislative process can include other avenues, such as amendments or negotiations, to potentially revive the bill's chances.
