Select the pair that best expresses a relationship similar to that expressed in the original pair:
OSTRICH : BIRD
Correct: C
An OSTRICH is a specific type of BIRD. This is a 'specific instance to category' relationship. Similarly, a SNAKE is a specific type of REPTILE. Kangaroo is a mammal is correct, but the given options for mammals usually have a less distinct 'type' relationship than ostrich to bird or snake to reptile. Whale : Fish is incorrect as a whale is a mammal, not a fish. Fish : Swimming describes an action, not a category.
