what is OA

Bhai · Answer

Given the information, may be they have some other disease. So measles is out of question and they may not be fine.

sperumba · Answer

But isn't that out of the scope of the stimulus.

My answer is C.

ceointhemaking · Answer

It is B because it is possible that one or two of the children have measles, and incorrect interpretation of information on both sides leads to the argument.

andy_gr8 · Answer

OA is B..Here;s the OE

(B) 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 Louis'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 Shirley could be wrong. We apologize for no making that clear in the explanation
