A two-thirds vote means two-thirds of which group?

A two-thirds vote is typically defined in parliamentary procedure as requiring the approval of two-thirds of those individuals who are present and voting at the meeting. This means that when a motion is put forth, the requirement is based on the number of votes cast by members who are actually in attendance and participating in the voting process, rather than the entire membership or a specific committee.

In a situation where only those present at the meeting are counted, it acknowledges that not all members may be able to attend or participate. Therefore, the decision reflects the will of the active participants at that specific time, providing a clear and immediate consensus among the members engaged in the discussion. This is why option C is the correct answer, as it establishes the necessary calculation of votes based on the present and engaged members at the meeting.

The other options may imply different groups that could lead to a misinterpretation of what constitutes a two-thirds vote. For instance, counting all members of the organization would not accurately represent the sentiment of those who are currently engaged. Similarly, limiting the vote to only the executive committee excludes the broader base of membership. Lastly, counting all members present without considering how many actually vote does not ensure that the decision reflects an active choice among the participating members.
