What did the Senior Warden say after verifying the individual's credentials?

The phrase uttered by the Senior Warden after verifying credentials signifies a necessary approval for the individual to advance within the meeting or ceremony. This choice reflects the Senior Warden's role in managing entry and ensuring that only those who are properly credentialed are permitted to continue deeper into the proceedings. The expression "pass on" indicates that the individual has met the requirements and is granted permission to move forward without any further delay, which aligns with the responsibilities of the Senior Warden in maintaining the flow and order of activities.

In contrast, the other options imply either a cautious or restrictive approach, such as advising caution or waiting, neither of which would denote a favorable verification of credentials. The command to "return to the entrance" would suggest a denial of access, which would be inappropriate following the successful confirmation of credentials. Thus, the correct response emphasizes the approval and facilitation of the individual's progress within the organization.
