Statement — A large part of the locality was flooded because the main pipe supplying drinking water burst while utility-company workers were laying cables.\nCourses of Action:\nI. The civic authority should immediately repair the damage and stop water loss.\nII. The civic authority should seek explanation and compensation from the utility company for the damage.

Introduction / Context:
An excavation-related burst of a water main caused flooding and wastage. Sound actions involve emergency containment and accountability for damages.

Given Data / Assumptions:

• Cable-laying coincided with the burst.
• I: Immediate repair to prevent further loss.
• II: Seek explanation/compensation from the utility contractor.

Concept / Approach:
Action I restores essential service and prevents property damage. Action II enforces due diligence, recovers public losses, and incentivizes safer excavation protocols (utility maps, permits, supervision).

Step-by-Step Solution:
1) Isolate segment, stop flow, pump out water.2) Repair/replace damaged section; test pressure/quality.3) Investigate contractor lapses; recover costs; revise SOPs.

Verification / Alternative check:
Public works best practice: emergency response plus post-incident accountability.

Why Other Options Are Wrong:
Only I/Only II/Either: incomplete response; Neither: ignores both urgent and systemic needs.

Common Pitfalls:
Stopping at repairs without learning/cost recovery.

Final Answer:
Both I and II follow.
