In congress, who has the right to unlimited debate and unlimited opportunity to offer amendments?
a. the vice president
b. citizens
c. the president
d. senators

The correct answer is D. Senators. U. S. Senators possess two traditional freedoms that no other legislators possess. The aforementioned freedoms are unlimited debate and an unlimited opportunity to offer amendments. Until 1917 these freedoms were subject to very few restrictions, but in 1917 the Senate adopted its first cloture rule (Rule XXII) to end a filibuster (holding the Senate floor to prevent a vote on a bil).

your answer would be (b)
