(B) It is possible that both Ellen and Lois are mistaken about Shirley's children.
(C) Either Ellen is right about Shirley's children, or Lois is right about them, but they cannot both be right.
(D) Ellen and Lois might both be right about Shirley's children, and they might both be wrong about them.
(E) None of these alternatives correctly identifies the possibilities for this scenario.


the case could also be that ellen wrongly diagnosed the disease as measles.

Tricky question!
I chose C at first, but after going through the explanations, I accept B
as better than C.

That would be out of scope.

I fell for C as well.

But I now see that it assumes that either ALL THREE are fine or ALL THREE have measels - but since those aren't the only two possibilities the only other sensible answer is B.

one more thing: the question does not ask us to take the above statements (comments by the speakers) as true. It only assumes that "nobody who has measles is fine."

I'd pick B because of "All children" as only one could be fine etc.

I fell for C too...there is a possibility that they are both wrong because Shirley's children have some other illness, therefore:

All three of Shirley's children DON'T have the measles!
As a matter of fact, all three of Shirley's children are NOT fine!

Who says children who dont have measles are always fine? Maybe they're having other problems. ;)

Which of the following must be true? Actually with the given information we can only predict both are wrong. We don't have enough information to predict the others. The first scenario is ruled out by assumption.

IMO-C

Nobody != Measels= Fine
Reverse is Everybody= measles != fine

Hence both the statements cannot be correct. Therefore C is the best option.
Can someone please confirm.To me the OA seems incorrect.

The correct answer is B. The reason I think is, consider a situation:

1 of the children has measles, 2 of them are fine.

In this case both E and L are wrong. So it is entirely possible that both are mistaken about the children.

This question is a real pain in the rear. I picked C at first, but I believe it is B based on what other members have said.

It is possible that the children do not have measles, they could be sick with something else.. Or two could have measles, one is fine.. etc. (Thus, we cannot make the blanket statement about all 3) Therefore, we cannot say that either Lois or Ellen must be correct. It is possible that both are wrong - B.

B for me too! Interesting question.

Both can be wrong as the discussion is about three children. If only one or maximum two of them have measles, then both are wrong since both the statements are about "all three".

Basically, in all cases in which all three are not in the same condition, both the statements would be incorrect.

Hope this helps.

Hi Experts,

The moment I saw C there was a hint of skepticism as it seems too clear and direct answer!

The bigger take away from this question is not the correct answer, but try to understand how gmat can trick us! (if this is a valid gmat problem).

I request experts to comment on this as to what should we take away from this kind of problem, if it's a legit gmat type problem.

To me C just seem to direct and I wanted to avoid it, but other choices didn't make much sense until I saw people's post here.

thanks

Accepting the assumption that nobody who has measles is fine, which of the following must be true about this exchange?

(A) It is possible that both Ellen and Lois are right about Shirley's children.
(B) It is possible that both Ellen and Lois are mistaken about Shirley's children.
(C) Either Ellen is right about Shirley's children, or Lois is right about them, but they cannot both be right.
(D) Ellen and Lois might both be right about Shirley's children, and they might both be wrong about them.
(E) None of these alternatives correctly identifies the possibilities for this scenario.


I went with option C and here is the explanation for my choice. I'll strict my explanation to only option B and C, since the discussions so far are only on these 2 options.

Let me start with my reason for rejection of option B:

The question says based on X assumption, which of the following must be true?

Option B says that It is possible that both Ellen and Lois are mistaken about Shirley's children.

Actually, no matter what Ellen and Louis say (you can forget about the passage also), this statement is always true. Because it is always "possible" for any two statements to be mistaken together. (Try to think of a situation where it is not even possible for both of them to be mistaken) There really is no need of any assumptions or premises, this statement always holds (only exception is when one says X is true and other says Not X is true).

S, if we say that option B must be true for this exchange, we are not really concluding anything.

Due to such a general nature of option B, I ignored it.

Option C says that:
Either Ellen is right about Shirley's children, or Lois is right about them, but they cannot both be right.

It says that both cannot be right together, which is true if the given assumption holds. Besides, it also leaves room for "both can be wrong". While some of the people have argued that option C means that one of E and L has to be correct, I don't agree.

As per Merriam Webster dictionary, either or means: (http://www.merriam-webster.com/dictionary/either-or)
an unavoidable choice or exclusive division between only two alternatives.

So, here if "either or" only means exclusive choice, not the unavoidable one, then both of them can be wrong.

Thus, option C is correct.

If anyone has any questions, please feel free to ask.

Regards,
CJ

Hi,

I posted about this question on Manhattan forums and got an expert to comment on it. The answer was quite what I expected.
This question is not a gmat, but a LSAT type question.

Friends please don't post LSAT questions on gmat forums. The point is not to just randomly solve any CR question but to see/solve more GMAT like questions.

thanks!
