Introduction / Context:
Invitations often include a start time and a request to be seated beforehand. We must identify the necessary assumptions behind such messaging.
Given Data / Assumptions:
- Message: Function starts at 3:00 p.m.; please be seated before then.
- Assumption I: Start is conditional on everyone being seated before 3:00 p.m.
- Assumption II: Organizers intend to begin on time (3:00 p.m.).
Concept / Approach:
The request for early seating facilitates a punctual start; it does not imply that the event cannot start if one person is late. The necessary presupposition is that the event is scheduled to start at 3:00 p.m., hence the seating request.
Step-by-Step Solution:
I is not necessary. The function could still begin on time even if a few seats are filled slightly later; the request simply aims to minimize disruptions.II is necessary. Without the intent to start at 3:00 p.m., asking guests to be seated “before 3:00 p.m.” lacks practical sense.
Verification / Alternative check:
Negating II (no intention to start at 3) renders the seating request arbitrary, weakening the message’s purpose.
Why Other Options Are Wrong:
I-only / Either / Both: Overstate the dependency on complete seating.Neither: Ignores the scheduling intention that motivates the request.
Common Pitfalls:
Interpreting a courtesy request as a hard precondition for commencement.
Final Answer:
Only assumption II is implicit
