I think I know the intent for answer choices like this, but I was taking a test today #32 October 2000 and on game #3 I was presented with answer choices asking where an object had to be placed. The answer choices were all x or y types.
If T is performed fifth and F is performed sixth, then S must be performed either
A fourth or seventh
B third or sixth
C third or fourth
D second or seventh
E first or fourth
S can be performed fourth or seventh and TCR is A. Are not choices C, D, or E logically correct as well? If one of the elements in an answer choice like this is true, then the answer is also true, right? Had the question been phrased "The two spots where S could be performed are..." this would not be an issue.
Can we ALWAYS rely that if one of the objects in an either or answer like this is not possible that the answer choice is incorrect?
