Stimulus

In order to determine automobile insurance premiums for a driver, insurance companies calculate various risk factors; as the risk factors increase, so does the premium. Certain factors, such as the driver’s age and past accident history, play an important role in these calculations. Yet these premiums should also increase with the frequency mishap increases in proportion to the number of times that person drives.

Which one of the following, if true, most undermines

Answer choices

  1. Opposite8% picked this

    People who drive infrequently are more likely to be involved in accidents that occur on small roads

    This makes infrequent drivers sound lower risk (their accidents are on remote rural roads so they don't cause as much damage as highway accidents do). We want an answer that makes frequent drivers sound lower risk, so that we can argue that their premiums should not increase.

  2. Correct82% picked this

    People who drive infrequently are less likely to follow rules for safe driving than are

    Why this is right

    This answer gives a reason why infrequent drivers are a bigger insurance risk than are frequent drivers: they break rules for safe driving more often. So this helps us argue the Anti-Conclusion. Premiums should not increase on frequent drivers. Even though their chance of being in an accident is increased by driving more times per year, their chance of being in an accident is decreased because they're more likely to follow safe driving rules.

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

  3. Opposite4% picked this

    People who drive infrequently are less likely to violate local speed limits than are people

    This makes infrequent drivers sound lower risk (they're less likely to break the speed limit). We want an answer that makes frequent drivers sound lower risk, so that we can argue that their premiums should not increase.

  4. Unclear Impact3% picked this

    People who drive frequently are more likely to make long-distance trips in the course of a year than

    Does this clearly give us a sense in which the frequent drivers are lower risk? Not really. We'd have to make up a story that "long-distance trips" are safer than local trips. We don't really know that. There's no clear, common sense connection there. When we compare it to the distinction in the correct answer (more likely to follow safety rules), this one would be a bigger stretch. It's easier to say "drivers who are more likely to follow safety rules" are lower risk drivers than it is to say "drivers who are more likely to make long-distance trips" are lower risk drivers.

  5. Opposite4% picked this

    People who drive frequently are more likely to become distracted while driving than are people

    This makes infrequent drivers sound lower risk (they're less likely to drive distracted). We want an answer that makes frequent drivers sound lower risk, so that we can argue that their premiums should not increase.
