Stimulus Summary

Low-wattage bulbs cost more but have many benefits, so everyone should use them.

Answer Anticipation

So many questions! 4 of these answers will raise an issue that we’d want to know about before determining if this argument is a good one.
The stimulus here is about a cost-benefit analysis of low-wattage bulbs. While these bulbs are expensive (cost) they have “enormous” advantages (benefits). However, the argument doesn’t really go into detail about these advantages, and how “enormous” they are compared to the cost. Any answer that brings up a piece of information relevant to that consideration will help us evaluate the argument. And since it’s a Bizarro question, we should eliminate those answers.

Answer choices

  1. A
    the actual cost of Remaining source text redacted.
    Why choice A is not credited
    This information would help us to evaluate a part of the cost of the switch, so it’d help in evaluating if the benefits are worth it.
  2. B
    the profits the home Remaining source text redacted.
    Why choice B matches the stem
    The stimulus is about the cost-benefit analysis for consumers, not for the producers of the bulbs, so this answer is out of scope and thus correct.
  3. C
    the specific cost of Remaining source text redacted.
    Why choice C is not credited
    This information would help us to evaluate a part of the cost of the switch, so it’d help in evaluating if the benefits are worth it.
  4. D
    the opinion of current Remaining source text redacted.
    Why choice D is not credited
    Knowing if they’re meeting the needs of the current users would help in evaluating the benefits of them - if people aren’t happy with them, then they’re probably not worth the cost.
  5. E
    the average life of Remaining source text redacted.
    Why choice E is not credited
    While a bit more indirect than (A) and (C), the longevity of the bulbs would help with the cost-benefit analysis. Since the bulbs are more expensive, if they have to be replaced frequently, that’ll drive the cost up quite a bit.
