Valid Argument #6 is messing me up

Here's what JY says:

All turtles know kung fu. All turtles are named after Italian artists. Therefore, some things that know kung fu are named after Italian artists.
[Lawgic]
A –> B
A –> C
_______________
B some C

I assume that would look like:
C
C
ABC
ABC
ABC
B
B
that makes sense.

Next Part:
An often overlooked corollary to this valid form is the following:

A –> C
B –> C
_______________
/A some /B



I assume that would look like:
/A
/A
/C/A/B
/C/A/B
/B
/B

Question:
I'm having trouble thinking of this in a sentence that actually makes sense/one that might appear on the test. help please?

    If you are not a fruit, you are not an orange. If you are not a fruit, you are not an apple. Some things that are not oranges are not apples, ie Darth Vader.

    So the corollary is definitely the tricky part.

    A ---> C
    B ----> C
    ---------------------
    /A some /B

    To represent this in English, you would say,
    "Some things that aren't A are also not B."

    Let's use the ninja turtles metaphor to substitute:
    A = ninja turtles
    B = Italian artists
    C = kung fu

    A ---> C (all ninja turtles know kung fu)
    B ---> C (all italian artists know kung fu)
    ----------------------
    /A some /B ("some things that ARE NOT ninja turtles, ARE ALSO NOT italian artists").

    So this corollary is essentially referring to whatever is OUTSIDE the intersection of ABC which you mentioned first:

    A ---> B
    A ---> C
    -----------------
    B some C

    I'm going to use { } to represent intersection relationships.

    {some B's} {all A's, some B's, some C's} {some C's}

    The corollary is merely describing whatever is NOT in those { } brackets.

    As for how it might appear on the test, I'm not entirely too certain. This seems like something that would appear in a Sufficient Assumption/Pseudo-Sufficient Assumption, so maybe it would help you to go over those particular lessons in the course. Sorry if this wasn't much help.

    Good luck!
