The question and its sources

The table shows five consecutive two-year sessions of Congress. Unified government means one party controlled the presidency, the House, and the Senate; divided government means it did not. A party-unity vote is a roll-call vote in which a majority of one party votes against a majority of the other party. Use the table to answer parts A, B, C, and D.
