Argument Completion Cards Question

For the card: P: C-most-A P: ? C: C-Most-not B I came up with two possible missing premises because they both seemed like the same thing: A-some-not B which means not B----->A and not B-some-A which means A---->not B The answer is A--->Not B and its contrapos. B--->Not A Why isn't the answer also A-some- not B so Not B--->A? Aren't "some" statements reversible, so both answers should be ok? I am confused as to how to know which is the correct answer. Thank You

How can you go from A-some-not B to not B ==> A?

P: C-most-A
P: ?
C: C-most-not B

We need a sufficient and necessary statement here since the conclusion is also "most".

C-most-A ==> not B

So the missing premise is:

A ==> not B
B ==> not A

Hope that helps!
