   Reversed Conclusion / Valid15% picked this

   Most cars taken to Acme Automotive Electronics have electrical problems. Therefore, it is likely that Anastasia’s car has electrical problems if she has

   This gives us the Most A's that are B are C. But it needs to conclude that, If this A is a C, then it's likely a B. or, equivalently, it it likely that B is true if C is true. The matching conclusion would have been, it is likely that A's car was taken to Acme if it has electrical problems. This conclusion actually is a valid inference from the Most premise.

   Most cars taken to Acme Automotive Electronics have electrical problems. Therefore, it is likely that Anastasia will take her car there

   Why this is right

   We have the same Most A's that are B are C We want a conclusion that's saying likely to be B, if C This conclusion does do that: likely to be Acme, if it has electrical problems What this argument and the original have in common that wasn't noted in our original breakdown of the argument is how the conclusion not only performs the reversed Most move, it also switches to a future tense. The original said, If he develops a pet allergy, he'll be likely to take allergy meds, since most people who take allergy meds have a pet allergy. This answer is saying If the car has electrical problems, she will likely go to Acme, since most people who go to Acme have electrical problems.

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

   Bad Conclusion Match2% picked this

   Most cars that are taken to Acme Automotive Electronics do not have electrical problems. Therefore, it is likely that Anastasia will not take her

   This conclusion involves some truth-value switching that the original argument didn't have. It goes from "do not have electrical problems" in the premise to "does have electrical problems" in the conclusion. And it goes from "do take to Acme" in the premise to "won't go to Acme" in the conclusion.

   Inferior Conclusion Match8% picked this

   Most cars taken to Acme Automotive Electronics have electrical problems. Therefore, it is likely that Anastasia will take her car to Acme Automotive Electronics

   This is real close. But the conclusion gets into her beliefs: "if she thinks the car has electrical problems". The original didn't say, "if Chuck thinks he has developed an allergy".
