      I don’t see much difference between Answer Option A & E

      Hi Rachel — those are very similar — the difference has to do with the orientation of the elements in the support vs the conclusion —

      Oversimplifying down to the relevant issue, the original argument gives us

      A -> B

      B is false.

      Thus, A must be false.

      (A) gives that to us as well.

      (E) gives us:

      A -> B

      A is false.

      Thus B must be false.

      Again, the original argument is more complicated than that (beliefs vs actuality etc.) but I hope that illustrates the differences between (A) and (E) — MK
