Question

Difficulty: Very hardStatement and Assumptions

Statement: To mitigate the rapid depletion of the municipal groundwater aquifer, the City Water Board has announced a tiered pricing structure where residential water tariffs will increase by 300% for monthly consumption exceeding 50,000 liters, while all new industrial extraction permits have been temporarily suspended pending a comprehensive hydrogeological review.

Which of the following assumptions are implicit in the above statement? (Select all that apply)

  1. Residential consumers possess the ability to alter their water consumption habits in response to substantial financial disincentives.Answer
  2. The proposed hydrogeological review will generate actionable data necessary to establish sustainable limits for future industrial extraction.Answer
  3. C
    Industrial water extraction is the primary and most significant cause of the recent rapid depletion of the municipal aquifer.
  4. D
    The revenue collected from the 300% residential tariff penalty will be exclusively utilized for artificial groundwater recharge projects.

Answer

The implicit assumptions are that residential consumers can alter their habits due to financial penalties, and that the hydrogeological review will provide actionable data for future industrial extraction.
An assumption is an unstated premise that must be logically true for an argument or action to be valid. For the residential tariff to function as a mitigation tool, it fundamentally assumes that affected consumers have the elasticity and ability to reduce their water consumption. Similarly, halting industrial permits explicitly 'pending a review' logically requires the premise that this review will be effective in generating actionable data to guide future permit limits.

Step-by-Step Solution

1
Analyze the core objective and the proposed actions in the statement.
Objective: Mitigate groundwater depletion. Actions: 1) Increase high-volume residential tariffs by 300%. 2) Suspend new industrial permits pending a review.
Deconstructing the statement separates the goal from the regulatory mechanisms.
2
Evaluate the residential tariff action for hidden premises.
The tariff acts as a deterrent. For a deterrent to work, the targeted demographic must be capable of changing their behavior. Thus, assuming consumers can alter their habits is logically necessary.
An administrative policy aimed at changing outcomes inherently assumes the target population can respond to its incentives.
3
Evaluate the industrial permit suspension for hidden premises.
The suspension is not permanent; it is explicitly tied to a 'hydrogeological review'. This requires the assumption that the review will actually produce useful data to resolve the administrative freeze.
A conditional administrative action assumes the condition (the review) is capable of being fulfilled and serving its intended purpose.
4
Screen remaining options for inferences, exaggerations, or external knowledge.
The claim that industry is the 'primary' cause is an over-inference not strictly required by the text. The claim about revenue allocation introduces outside policy expectations entirely unsupported by the text.
Assumptions must be absolutely necessary for the statement to hold true, not merely plausible real-world possibilities.
