Final answer:
The true statement is that a chamber is a legislative meeting hall. An override requires a two-thirds vote in both houses, not three-fourths. Conference committees handle bill reconciliation, and the British Parliament has no voting rights on U.S. congressional bills.
Step-by-step explanation:
The statement that is true regarding U.S. legislative procedures is this: a chamber is a legislative meeting hall. This statement refers to a space where legislative sessions are held. In contrast, an override of a presidential veto requires a two-thirds vote in both chambers of Congress, not a three-fourths vote. A 'sitting bill' is not a term commonly used to describe a bill in active progress. A conference committee is indeed formed to reconcile differences between the House and Senate versions of a bill, not for re-election purposes. The British Parliament does not vote on U.S. congressional bills at all, let alone on a biennial basis.
It's important to note that other claims about legislative procedures, such as the ability of the Senate to filibuster or the requirement for both the House and Senate to pass identical bills for a law to be enacted, are correct. Moreover, bills often perish in committee if they do not find enough support, and if the president vetoes a bill, the legislature can attempt to override the veto with a two-thirds majority vote in both the House and Senate.
