Final answer:
The question is about the majority required by a board to revoke a license, suggesting that a supermajority vote, similar to the legislative requirement of a two-thirds vote, is necessary for such a decision.
Step-by-step explanation:
The question pertains to the specific majority required by a board to revoke a license. In the context provided, the term “every bill” disapproved by the president requiring a two-thirds vote in both the Senate and House of Representatives suggests a parallel in the process of revocation of licenses by a board.
While the original sentence does not specify the exact fraction it can be inferred that a supermajority vote often two-thirds like in the legislative process, may be required in the context of a board's decision-making for license revocation to ensure a significant consensus is reached. Such a requirement underscores the importance and seriousness of the decision at hand.
