Ellen: All three of Shirley's children have the measles!
Lois: As a matter of fact, all three of Shirley's children are fine!
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.
Lois: As a matter of fact, all three of Shirley's children are fine!

Actually C overlooks the fact that both can be wrong but B says possibly hence no restriction on other conditions !!!EXTREME choices are often not correct !!!
B is best :
its possible 2SC have M and 1 sc does not
1 sc is fine 2 are not
BOTH WENT WRONG here hence this scenario needs to be taken care .But C does not give any space for this it says either of them should be correct which is wrong

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.
This is not the correct answer because someone who has measles cannot be fine and one of them says they all have measles and the other says they're all fine.
(B) It is possible that both Ellen and Lois are mistaken about Shirley's children.
This is the correct answer. It's perfectly possible that neither of them have measles. However, that doesn't mean they're all fine. They can be not fine for some other reason other than measles.
(C) Either Ellen is right about Shirley's children, or Lois is right about them, but they cannot both be right.
They cannot both be right but it doesn't mean one of them has to be right. See (B)
(D) Ellen and Lois might both be right about Shirley's children, and they might both be wrong about them.
They might be both wrong about them, but they can't be both right
(E) None of these alternatives correctly identifies the possibilities for this scenario.
Not true for the only reason that B is right. Kinda silly
