Kim has no reason to believe that Sada will win the election, and she also has no reason to believe that Brown will win the election. So the author concludes that Kim has no reason to believe either Sada or Brown will win the election. As in the stimulus, the author here overlooks one possibility: it’s possible that Kim has reason to believe that no one else will win the election (maybe no one else is running), in which case she has reason to believe that the winner will be either Sada or Brown!

Wrong flaw. The conclusion here isn’t valid—maybe there’s no proof of either theory, but one of the options could still be less plausible! What if the vent in the ceiling isn’t big enough for a person to get through, or the window is 100 stories up? But that’s not the flaw from the stimulus: here, the conclusion is that both options are equally possible; in the stimulus, the conclusion is that there’s no proof that the truth lies in one of the two options presented.

Wrong flaw. This argument relies on a misunderstanding of the quantifier “most.” Let’s say there are 100 students in the author’s dorm: 51 are engineering majors and 51 are from out of town. One student must be both an engineering major and from out of town, but the others could fall into only one of those two categories! In that case, most of the engineering majors aren’t from out of town. But this isn’t the same flaw we saw in the stimulus, where the premises don’t include “most” relationships.

Wrong flaw. The parts of the forest where camping is permitted could be completely separate from the parts where hunting is permitted! But this isn’t the flaw from the stimulus, where the premises don’t include “some” relationships.

Wrong flaw. Just because the car could’ve been driven by Jones or Katsarakis doesn’t mean they both could’ve driven the car! How would that even work? Regardless, this isn’t the flaw from the stimulus—the stimulus concludes that there’s no evidence that the truth lies in one of the two options presented, whereas (E) concludes that both options could be true simultaneously.
