Final answer:
A joint committee is created to work out a compromise on House and Senate versions of a piece of legislation.
Step-by-step explanation:
In the legislative process, when there are different versions of a bill that need to be resolved, a joint committee is created to work out a compromise between the House and Senate versions of the legislation. This joint committee consists of members appointed from both the House of Representatives and the Senate. The committee is responsible for reconciling the differences between the two versions of the bill and coming up with a final version that can be passed by both chambers.
