Statement: The weather bureau has forecast heavy rainfall during the next week, which may cause water-logging in several parts of the city. Courses of Action: I. Give the bulletin wide publicity through mass media and civic channels. II. Keep pumping systems and de-watering teams on standby to remove accumulated water from vulnerable areas. III. Advise people to stay indoors throughout the period. Which course(s) of action logically follow(s)?

Introduction / Context:
Advance warning of heavy rain enables risk communication and preparedness. Logical actions spread the forecast and pre-position de-watering capability. A blanket instruction to “stay indoors” for an entire week is overbroad and impractical unless there is an extreme hazard advisory.

Given Data / Assumptions:

• Forecast: Heavy rainfall; water-logging risk.
• Objective: Minimize disruption and flooding impacts.
• No curfew-level threat is indicated.

Concept / Approach:
Risk-proportionate actions include alerting residents (I) and readying pumps and teams (II). Advising continuous indoor stay (III) is excessive; targeted advisories (avoid underpasses, park on higher ground) would be more apt but are not among the options.

Step-by-Step Solution:

Verification / Alternative check:
Standard monsoon SOPs emphasize alerts and pumping readiness.

Why Other Options Are Wrong:

Common Pitfalls:
Issuing blanket restrictions without corresponding hazard levels.

Final Answer:
Only I and II follow.
