Statement–Assumption — “Residents are advised to use mosquito repellents or sleep under nets as many people are suffering from malaria.” — Civic authority advisory Assumptions: I) Local residents can afford repellents or nets. II) Some people may ignore the advice due to other pressing needs. Choose the implicit assumption(s).

Introduction / Context:Public-health advisories typically presume citizens can act on the suggested measures. Here, the measures (repellents/nets) have a cost component.

Given Data / Assumptions:

• Action required: procure or use repellents/nets.
• Purpose: reduce malaria exposure.

Concept / Approach:The advisory is meaningful only if residents are in a position to follow it—i.e., affordability/availability exist (Assumption I). A conjecture that people “may ignore” due to other needs (Assumption II) is not necessary for issuing the advisory; authorities do not need to assume non-compliance to recommend best practices.

Step-by-Step Solution:

Verification / Alternative check:If residents could not afford nets/repellents at all, a different advisory (e.g., community fogging) would be expected.

Why Other Options Are Wrong:Choosing II alone or “either” introduces unnecessary speculation; “neither” ignores feasibility.

Common Pitfalls:Equating “some will ignore” (empirical) with an assumption needed to issue advice (logical).

Final Answer:Only assumption I is implicit.
