Difficulty: Easy
Correct Answer: Only I is implicit
Explanation:
Introduction / Context:
A public advisory asks residents to stay home due to a tense, uncontrolled situation. We must find the minimal assumptions behind issuing such guidance.
Given Data / Assumptions:
Concept / Approach:
An advisory presupposes a real safety threat (I). It need not assume particular behavioral outcomes (II) nor forecast when normalcy returns (III).
Step-by-Step Solution:
1) Without serious incidents or credible threat, a “stay home” advisory would lack justification; I is necessary.2) II, that people will not go to the office, is an outcome, not a precondition; advisories can be issued even if some ignore them.3) III is a prediction unnecessary to the current advisory; the statement does not hinge on quick restoration.
Verification / Alternative check:
Authorities can advise caution without committing to behavior compliance or timelines.
Why Other Options Are Wrong:
They add behavior certainty or future forecasts absent from the advisory’s logic.
Common Pitfalls:
Reading unstated optimism or compliance into emergency messages.
Final Answer:
Only I is implicit.
