Question on #7

Hi Marissa, thanks for the question If H is used only once, that means that H is used only in Policy. Meaning that F and G must be placed in Quality and Sales. Since G conflicts with L and L has yet to be placed. It cannot be G in both Quality and Sales. Additionally, since F conflicts with M in this scenario, it too cannot be placed in both Quality and Sales. This means we are left with G in either Quality or Sales and F in either Quality or Sales. We can create two hypotheticals to show this. H __ __ G __ G F F K OR H __ __ G __ F F G K In the first scenario, we fill Sales with M to not conflict with F. Additionally, L in Quality to not conflict with G. In the second scenario we fill Sales with L to not conflict with G. Additionally, M in Quality to not conflict with F. H __ M G L G F F K AND H __ L G M F F G K Lastly, the only available variable to fill both Qualities is K. Which is why it is used twice in both hypotheticals. I hope this helps!

Why is K the only available variable?

ohh I just read the other question's answers and see now that one person can't hold two positions on the same committee
