If H is assigned to exactly one committee, and if no committee has both F and M assigned to it, then it must be true ...

Question about #7
For #7, I initially thought K had to be assigned to Sales; with that assumption, I came up with these possibilities:
Policy: F G H
Quality: G M M
Sales: F K L
And,
Policy: F G H
Quality: F L L
Sales: G K M
If these are valid, how can C be the answer?
Thanks,
Tony

The video doesn't explain why you can't have F L L or G M M in Quality like the guy asked above. Very disappointing that you didn't answer his question or Kenny's question in the other discussion post.

@zcrabill to answer your question, try thinking about how it could be possible to have two slots filled by the same person.. you can't.

why can't M appear twice in quality ?

@a49er2, @zcrabill, and @clauv123
Great questions.
@zcrabil, You can't have F L L . or G M M in Quality because one person cannot occupy two spots in a committee. In other words, within each committee, the people need to be different within that committee.
@a49er2, the only two possible scenarios for #7 are
P Q S F F G G L M H K K
or
P Q S F G F G M L H K K
The inference we get from this is that K must be in exactly 2 committees, so answer (C) is our choice.
We arrive at these two scenarios by combining the rule that G and L can't be together with the other rules mentioned in #7 s stimulus that F and M can't be together and H is only in one committee.
