Statement:\n“The monsoon is here, and so are the mosquitoes. Beware of deadly diseases! Do not leave, on rooftops or in the open, unused or broken articles like bottles, cups, tyres, etc.,” says a public-interest notice from the Directorate of Health Services (DHS).\n\nAssumptions:\nI. Mosquitoes spread fatal diseases, and controlling mosquito breeding can prevent disease spread.\nII. Unused/broken articles are capable of holding rainwater.\n\nWhich of the above assumptions are implicit in the statement?

Introduction / Context:
The health advisory links monsoon conditions to mosquito-borne diseases and instructs citizens to remove water-holding junk. For the advice to be rational, two premises must hold: mosquitoes transmit serious disease (and breeding control helps), and common discarded items collect water where mosquitoes breed.

Given Data / Assumptions:

• Warning: Risk of diseases increases with mosquito proliferation.
• Action: Avoid leaving items that collect water (bottles, cups, tyres).
• Assumption I: Vector control reduces disease transmission; mosquitoes spread fatal diseases.
• Assumption II: The listed items retain rainwater, enabling breeding sites.

Concept / Approach:
Vector-borne disease prevention strategies rest on cutting breeding sites (stagnant water). Therefore, the instruction assumes both epidemiological causation (I) and environmental conditions favoring breeding (II). Either assumption failing would undercut the reasonableness of the directive.

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

Common Pitfalls:
Overlooking that breeding control (environmental sanitation) is a primary public health intervention alongside personal protection.

Final Answer:
Both Assumptions I and II are implicit.
