Answer:
B. cloture motions
Explanation:
A cloture motion is a procedural motion, voted on by a three-fifths majority, that brings long and irrelevant speeches and debates to a quick end so that congressmen can vote on the bill, amendment or motion discussed. This procedure only happens in the Senate because in this house Senators are allowed to speak for as long as they wish, and propose many amendments as they want.
The House of Representatives, on the other hand, whose size is larger than the Senate's, has more rules for floor debate and does not allow unlimited debates, and therefore, Representatives do not vote on cloture motions.
