Sure, see if this helps. Not all house cats are calicos. All house cats are mammals. A: Not all calicos are mammals. B: Not all mammals are calicos. C: No mammals are calicos. D: No calicos are mammals. E: No valid conclusion.
Does that help clarify?

I got this daily drill incorrect, so I really want to go over it in depth if I may!
^the answer is B) Not all mammals are calicos? Is that correct?
Because;
Not all house cats are calicos translates to:
house cats - some - not calicos Or Not calicos - some - house cats
And all house cats are mammals Which translates to
house cats -> mammals
And so the correct inference would combine them, as in:
Not calicos - some - house cats -> mammals
So not calicos - some - mammals Or Mammals - some - not calicos
And that conclusion correctly translates to:
Not all mammals are calicos right? So B) is the correct answer?
and A) is not the correct answer because:
not all mammals are calicos (mammals - some - not calicos) is not the same thing as:
[even though these variables are in a SOME statement, they cannot just be reversed without carrying over the negation of calicos, that’s probably what I overlooked when I got this wrong at first]
Not all calicos are mammals (Calicos - some - not mammals)
If possible, please let me know if my reasoning is correct and the answer to Anita’s problem is really B, thank you.
