PT36 S4 Q5, 6

Hi,
I'm having trouble with both q's 5 and 6. For 5, I eliminated a as well as d, and then got stuck. For 6, I ended up crossing them all out.

Hey,

So, the question asks: If the stand carries watermelons, then what cannot be true.

Well, the last rule states that if the stand carries watermelons, then it carries either figs or tangerines (or both).

1) W --> F or T (or both).

We also know via the second rule that if the stand does not carry tangerines, then it carries Kiwis. Or if it does not carry Kiwis, it must carry tangerines.

~T --> K
~K --> T

Using this information, answer choice (E) should stand out.

If the stand carries pears, but not tangerines, this means that the stand must also carry Kiwis.

This, however, would violate rule 1, which states that if the stand carries Kiwis, then it does not carry pears.

K <--|-->P

Therefore, (E) cannot be true.

As for question (6), answer choice (C) should stand out.

C is correct because it has oranges, pears and watermelons, but it does not include figs or tangerines (or both).

Remember, when we have watermelons, we must have f or t or both.

Hope this helps.

Thanks for the explanation! I edited your post; you meant answer (E), not (D).

A simpler way to think about number 5 is that if P is in, K must be out, and T must be in. So you can't have P without T.
