Statement & Assumption — “The function will start at 3:00 PM. You are requested to take your seats before 3:00 PM.” Which assumptions are implicit? I. If an invitee is not seated before 3:00 PM, the function cannot start. II. The function will start as scheduled at 3:00 PM.

Introduction / Context:
The invite indicates a precise start time and asks guests to be seated beforehand. We determine which premises must be true for this request to be sensible.

Given Data / Assumptions:

• There is a scheduled start at 3:00 PM.
• Seating before the start improves orderliness and punctuality.

Concept / Approach:
Assumption II is implicit: the organizers intend to begin at the scheduled time, hence the request to be seated earlier. Assumption I is not necessary; the event can still begin even if a few invitees are not seated—organizers commonly begin on time regardless.

Step-by-Step Solution:
II: Necessary—punctual start is the rationale for the instruction.I: Too strong—does not follow that one late invitee blocks the start.

Why Other Options Are Wrong:
Any option including I imputes an absolute dependency that is not required for the instruction to make sense.

Common Pitfalls:
Treating a courtesy/operational request as a strict functional precondition.

Final Answer:
if only Assumption II is implicit
