Statements: Airlines request bona fide passengers to check flight status before leaving home because heavy fog is causing major disruption to normal operations. Which assumptions are implicit?

Introduction / Context:Operational advisories aim to reduce passenger inconvenience by altering behaviour (check status before travel). We determine which assumptions must hold.

Given Data / Assumptions (from options):

• I. A majority of passengers will check status before starting.
• II. The Government may object to the notice.
• III. A majority may cancel tickets and postpone journeys until normalcy returns.

Concept / Approach:An advice assumes some compliance by its audience. It need not assume government objection or mass cancellations.

Step-by-Step Solution:I: If most passengers will not check, the advisory would have little effect. The airline assumes compliance to mitigate crowding and frustration. Implicit.II: There is no basis for government objection; the message is informational. Not implicit.III: The airline does not need to assume mass cancellations; it only wants passengers to verify status. Not implicit.

Verification / Alternative check:Advisories during fog are standard and presuppose that many passengers will act on them.

Why Other Options Are Wrong:Options citing II or III add unwarranted speculation.

Common Pitfalls:Assuming extreme public reactions when the statement only requests a simple check.

Final Answer:Only I is implicit.
