Statement–Assumption — “The civic body urges residents to voluntarily cut potable water use by ~30% to tide over the water crisis.” Assumptions: I) Many residents may comply and reduce consumption. II) Activists may welcome the move and spread awareness among residents. Choose the implicit assumption(s).

Introduction / Context:Appeals for voluntary conservation presume that at least a meaningful fraction of the audience will respond. Without such an expectation, issuing the appeal would be futile as a crisis-mitigation measure.

Given Data / Assumptions:

• Situation: water crisis.
• Action: voluntary 30% cut in usage requested.

Concept / Approach:Assumption I is necessary: the civic body expects enough residents to comply for the measure to have aggregate impact. Assumption II about activists’ support is not required; the appeal can be justified regardless of activist involvement. Activist participation could help, but the decision to issue an appeal does not depend on presuming it.

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:Choosing II (or either/neither) misidentifies the minimal premise enabling the appeal to be effective.

Common Pitfalls:Confusing helpful amplifiers (activists, media) with necessary assumptions.

Final Answer:Only Assumption I is implicit.
