Suppose that in the Venn diagram of the premises of a categorical syllogism, there is an X on the line between areas 2 and 3. But in the diagram of the conclusion, the X is on the line between areas 2 and 5. Is the syllogism valid?
 Selected Answer: d. Yes, because if something exists in either area 2 or area 3, then necessarily something exists in area 2 or area 5. Answers: a. No, because proving that something exists either in area 2 or area 3 is not enough to prove that something exists either in area 2 or area 5 (it could exist only in area 3). b. No, because the Xs are not in precisely the same place in the two diagrams, which is a requirement for validity. c. Yes, because there is no shading to consider. d. Yes, because if something exists in either area 2 or area 3, then necessarily something exists in area 2 or area 5. e. Yes, because the two Xs border the same area, area 2.
