Answer:
b. early 1900s.
Step-by-step explanation:
The act of debating about any legislation involves filibusters who try to prevent or even delay any proposed law from being adopted or finalization of any decision. This procedure resulted in the adoption of the cloture rule, which pertains to the permission of members of the legislation to have a say in the debate.
This cloture rule was adopted on March 8, 1917, bringing upon the change that allows a two-thirds majority for a debate to be concluded. This 65th session of the Congress also allowed the members to have the time to speak for another one hour before the voting for a final decision is taken.
Thus, the correct answer is option b, the early 1900s.
