Stimulus

The town of Springhill frequently must declare a water emergency, making it temporarily unlawful to use water for such nonessential purposes as car washing. These emergencies could be avoided if Springhill would introduce permanent economic incentives for water conservation. Actually, Springhill discourages conservation because each household pays a modest monthly flat fee and a substantial per-liter rate only after the threshold is reached.

Which one the following, if true, most strengthens

Answer choices

  1. No Impact9% picked this

    The Springhill authorities do a poor job of enforcing its water emergency laws and many people break the

    We don't care about whether emergency laws are enforced. We're trying to discuss a plan for getting people to conserve more water (which would keep water emergency laws from even being needed). This doesn't directly comment on whether changing the pricing structure would effectively aid in water conservation.

  2. No Impact6% picked this

    The town council of Springhill recently refused to raise

    This is just describing that the town council didn't do something. It has nothing to do with assessing whether following the author's Plan would bring us closer to the Goal.

  3. Correct75% picked this

    The threshold is kept at a high enough level to exceed the water requirements of

    Why this is right

    This affirms the author's assumption, that people are not being encouraged to conserve by the current system. If the threshold is high enough to exceed the water requirements of most households, this means that many people never exceed the threshold and therefore don't face the substantial per-liter rate. This highlights the inadequacy of the current pricing structure to encourage conservation, as the usage threshold is not motivating enough. Bringing in economic incentives would directly target the problem of overuse below the threshold and could more effectively reduce overall water consumption, supporting the plan to avoid emergencies.

    Skill tested: Strengthen · how this choice captures the argument's function is the move to repeat next time.

  4. Opposite (if anything)4% picked this

    The threshold is not as high in Springhill as it is

    The lower the threshold, the more people will be motivated to conserve water (because once they pass the threshold, water use gets much more expensive). So if anything this tells us that Springhill has a more moitvating threshold than its neighbors do.

  5. No Impact6% picked this

    The threshold remains at the predetermined level specified by law until a change is approved by

    This merely tells us about the procedure for threshold adjustments, not its effectiveness or shortcomings to prevent water emergencies.
