Every adult male woolly monkey is larger than even the largest female woolly monkey. In colonies of woolly monkeys, any adult male will dominate any female. If the statements above are true, which one of the following must on the basis of them be true of woolly monkeys in colonies? ['If a female woolly monkey dominates a male of the species, the dominated male monkey is not an adult.', 'Some large adolescent male woolly monkeys dominate some smaller females of the species.', 'Size is the primary determinant of relations of dominance among woolly monkeys.', 'If a male woolly monkey is larger than a female of the species, that male will dominate that female.']
