this was tough. I chose C in the end.

B also came close but the word "possible" put me off, suggesting that there is a possibility that both could be right which violates our assumption which is that having measles is not fine.

A) It is possible that both Ellen and Lois are right about Shirley's children.

Both can't be right at the same time as long as they are talking abt the same Shirley.. :)

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

This is possiblem when one kid has measles and other two don't.

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

No need that one of them has to be right..

D) Ellen and Lois might both be right about Shirley's children, and they might both be wrong about them.

Both can't be right..

E) None of these alternatives correctly identifies a possibility for this scenario.

B is somewhat making sense.. But ideally I would like to say - both can't be right, but both or either can be wrong.

I am choosing B over E.

B it is.

C is also tempting but how can we infer that one of them must be true. They both can be wrong because children have some other disease.

Yes, B. What if the kids have some other sickness or are temporarily feeling bad?

B for me.

Both people are mistaken about the fact that the kids have measles. Hence each think she is right.

please explain


I may be wrong . I understood like this.... please help me guys....

Anyone who has measles is fine i.e all are ok so Luis is right
Nobody who has measles is fine (opposite meaning) luis is wrong.

Here Ellen is right about information whereas Luis is not.

So I want to go for the answer C.

I went with C, but OA is B :cry:

OE:
These two statements are called 'contraries.' That is, they cannot both be true, but they can both be false. The latter would valid if, for example, two of Shirley's children had measles and the third one was fine. But no combination of illness and health in Shirley's children will allow both Ellen and Lois's statements to be true. (C) is incorrect because there is no reason why either one of them has to be correct. Both Ellen and Lois could be wrong.
