Statement: “Due to urgent repairs on a main line from the Wazirabad waterworks, water supply will be at low pressure on Thursday.” Assumptions I & II: I. Repair work impedes normal water supply. II. Water will still be available, albeit at low pressure. Choose the option that correctly identifies the implicit assumption(s).

Introduction / Context:The notice informs consumers about low water pressure on Thursday because of urgent repairs on a main line. Notices of this kind assume certain background facts about cause and effect and expected availability.

Given Data / Assumptions:

• I. Repairs impede normal supply (cause of reduced pressure).
• II. Supply will continue, though at reduced pressure.

Concept / Approach:For the notice to be informative, it must rely on repair work affecting pressure and on the notion that water will not be fully cut off.

Step-by-Step Solution:1) The causal link between “urgent repair” and “low pressure” is assumed (I).2) Stating “low pressure” presumes there will still be water (II); otherwise “no supply” would be announced.3) Therefore, both I and II are implicit.

Verification / Alternative check:If repairs did not affect supply, no reason for pressure change exists. If water were unavailable, the notice would warn of a total shutdown, not mere low pressure.

Why Other Options Are Wrong:Only I/Only II: each omits an essential part of the communicated situation. Either I or II: both are required. Neither: plainly false.

Common Pitfalls:Missing that “low pressure” communicates partial continuity of service.

Final Answer:Both I and II are implicit.
