For the card:
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.
