QUESTION TEXT: Sheila's response depends on the presupposition that…
QUESTION TYPE: Necessary Assumption
CONCLUSION: Sheila thinks it is not a good idea to install speed bumps and warning signs.
REASONING: She thinks that people who hit speed bumps could have accidents if they are driving too fast.
ANALYSIS: Most people slow down when they see speed bumps and signs that say “slow down!” They don’t want to hurt their cars.
Sheila is assuming that at least some people won’t slow down and will still drive fast enough to hurt themselves on the speed bumps.
- It doesn’t matter how bad the problems are in other cities. The proposal is limited to Crownsbury.
- Sheila is clear that Robert is actually trying to address accidents. This answer choice is way off base.
- CORRECT. If every driver slowed down then no driver could drive too fast and have an accident on a speed bump.
- It’s not necessary that any people affected by the problem be harmed. It’s only necessary that some of the people causing the problem (the speeders) would be harmed by speed bumps.
- The proposal is limited to residential streets. Non-residential streets are irrelevant.
