#10 - Local, Cannot Be True

Complete Question Explanation

The correct answer choice is (B)

If Casey buys exactly one medium shirt, and all three shirts are different colors, only two possible solutions exist:

• 1. MR, SY, SB 2. MB, LY, LR

In neither case does Casey buy a medium yellow shirt, and thus answer choice (B) is correct.

Can someone tell me why these are not possible solutions:

MR MY SB
MR MY LR

Thank you for your most immediate response.

The question indicates that Casey buys exactly one medium shirt. Your two hypotheticals have her buying two medium shirts, which is not possible.

Therefore, can Casey not buy two of the same colours of shirts even if the shirts are different sizes?

Hi,

Yes, the question specifies (as a local rule) that Casey cannot buy two shirts of the same color, and so that's why when she buys the yellow medium, she has to buy either two small shirts or two large shirts (given the global rule that she can't buy a small and a large shirt together), which she can't do since there are no small red shirts and no large blue shirts (meaning she can't buy SR, SB or LR, LB).
