Q16

by jamel.exhem Thu Sep 27, 2012 9:18 pm

PLEASE REFER BACK TO NUMBER 15. ok. If A is true, why can't B be true? Is not true that Lara could buy a hot dog? To my understanding, Lara could either buy exactly a Fruit Cup and a Hot Dog, or a Fruit Cup and a Shish Kebob. The answer choices say that A. Lara buys a fruit cup, and B. Lara buys a Hot Dog...which she theoretically could do either! I'd understand more it if said "Lara MUST buy a Fruit Cup, because I find that to be true. But the same way she buys the fruit cup, she buys the hot dog. Why is A more correct that B?

This is the issue. This is a must be true question stem. It must be true that Laura has F. The condition given to us in this question is that Laura has exactly 2 slots. We have a H ---> ~S rule, which is a "not both" rule. It could be true that H is selected and it is also could be true that S is selected, but it does not have to be true.

Maybe a moderator can move this discussion to the #15 thread.

Just to add, we know L can never have P and the prompt limits her options to two vendor foods. This leaves F, H or S.

We know that one of the rule implies H and S can never be together, suggesting that H OR S must fill one of the two options for L. As such, F MUST BE the remaining vendor food.

For answer choice B, its a could be true.
