It is an inference question. Statement A must be true. She will either eat fried rice or an egg roll but not both.

Juana is dining at a Chinese restaurant. She will order either combination platter #2 or combination platter #5, but not both. If she orders combination platter #2, she will eat fried rice. If she orders combination platter #5, she will eat an egg roll. Given the statements above, which of the following must be true?

If #2 => fried rice
If #5 => egg roll

(A) Juana will eat either fried rice or an egg roll but not both.
Wrong. She could order #2 only and eat both fried rice and egg roll.

(B) If Juana eats an egg roll, then she ordered combination platter #5.
From "if A then B" we cannot deduce that "if B then A"

(C) If Juana does not eat an egg roll, then she ordered combination platter #2.
Correct. Logic is "if A then B" then "if not B then not A"

(D) If Juana eats fried rice, then she ordered combination platter #2.
Same as B

(E) Anyone who orders combination platter #2 eats fried rice.
Wrong.

@broall- can you please explain your line of reasoning for A. Why did you say... she could order platter 2 only and eat both? By this logic... she could order platter 5 only and eat both too? Thanks for the help!

That is the trick in this question. The question said that she could order either #2 or #5, this means that she can't order both or none.

However, the question didn't said that she could only order either fried rice or egg role. This means that she could buy additional things as she wishes. For example, she order #2, so she must eat fried rice. However, she could still buy egg role. That's the case in choice A.

Hope that helps.

Quote:
She will order either combination platter #2 or combination platter #5, but not both. If she orders combination platter #2, she will eat fried rice. If she orders combination platter #5, she will eat an egg roll.

so ...
1) she will eat either #2 or #5 but not both
2) Egg roll and fried rice are NOT dependent on #2 or #5 BUT #2 or #5 are dependent on egg roll and fried rice

actual meaning..
1) If she orders combination platter #2, she will eat fried rice..
If NO fried rice, NO #2
2) If she orders combination platter #5, she will eat an egg roll.
If NO egg roll, NO #5

C follows this LOGIC so C

@broall- excellent insight. Sorry to use a metaphor. In zen, there is something called awakening. Sometimes people struggle with something for hours, days or year and they can't figure out the answer. And they have a moment of enlightenment.

Although I just saw the question today, but I couldn't see it any other way. Thanks for showing this angle. I think I just had my aha moment. Thanks a lot!

Juana is dining at a Chinese restaurant. She will order either combination platter #2 or combination platter #5, but not both. If she orders combination platter #2, she will eat fried rice. If she orders combination platter #5, she will eat an egg roll. Given the statements above, which of the following must be true?

(A) Juana will eat either fried rice or an egg roll but not both. -We just know that she will order combination 2 or 5. She can order both egg and rice alongside it.
(B) If Juana eats an egg roll, then she ordered combination platter #5. -As per explanation in point A, B is incorrect.
(C) If Juana does not eat an egg roll, then she ordered combination platter #2. -Correct. If she orders 5 then she will eat egg. So if she doesn't eat egg, then that means she didn't order 5. Thus she must order 2.
(D) If Juana eats fried rice, then she ordered combination platter #2. -As per explanation in point A, D is incorrect.
(E) Anyone who orders combination platter #2 eats fried rice. -Anyone? Incorrect

IMO C

flatter 5 --> egg roll

no egg roll --> no flatter 5 (obviously flatter 2). we are told that "She will order either combination platter #2 or combination platter #5, but not both".

It has to be C, contrapositive !

(A) Juana will eat either fried rice or an egg roll but not both. - can eat both also. if #2 -> fried rice, but can also egg roll also
(B) If Juana eats an egg roll, then she ordered combination platter #5. - mistaken reversal => if A -> B, if B NEED NOT BE A
(C) If Juana does not eat an egg roll, then she ordered combination platter #2. -> contrapositive -> if A -> B => if ~B -> ~A
(D) If Juana eats fried rice, then she ordered combination platter #2. -> Same as B - mistaken reversal
(E) Anyone who orders combination platter #2 eats fried rice. -> Out of context.
