If the statements above are true, which one of the following must on the basis of them be true of woolly monkeys in colonies?
(A) Size is the primary determinant of relations of dominance among woolly monkeys.
(B) Some large adolescent male woolly monkeys dominate some smaller females of the species.
(C) If a male woolly monkey is larger than a female of the species, that male will dominate that female.
(D) If a female woolly monkey dominates a male of the species, the dominated male monkey is not an adult.
(E) An adult male woolly monkey can dominate a female of the species only if that female is also an adult.
If you like math, this is the classic example of sets.
Premise 1: Every adult large monkey is larger than the largest female monkey.
Premise 2: Any adult male will dominate any female.
No conclusion is presented over here. Also, key differentiator is the absence of cause and effect relationship. These are just presented facts.
A. We have just the facts. We cannot assume that one leads to other. Eliminate A.
B. May or may not be true. We know only of adult monkeys not the adolescent ones. Eliminate B.
C. Again causal relationship is presented. Eliminate C.
D. Since we know of adults, we could infer this. Any adult male can dominate a female. So, if a male is being dominated, then we can safely say that the male is not adult yet. Hold on.
E. Directly contradicts the premise. Any adult male will dominate any female, irrespective of size or maturity. Eliminate E.
Option D is the best out of five.
