b) Suppose that b is small and d is large, and further that either b and d are identical or that c is a tetrahedron. Max believes that c must be a tetrahedron on the basis of this information. Which of the following is true of this situation? 1. Max is correct to believe that we can determine the shape of c but it is not a tetrahedron, since the given information is contradictory. 2. Max is mistaken, and nothing can be concluded about c, after all c is only mentioned in one of the disjuncts of a disjunction. 3. Max is correct, because there is no situation in which b is small, d is large and b and d are names of the same objects. 4. Max is correct, because it there is no situation in which b is small, d is large, and c is a cube.
