Let's analyze the options: - Nest, Stable, and Hole are all places or structures related to specific animals. - Nest is a place where birds live. - Stable is a place where horses are kept. - Hole refers to a structure often associated with animals like rabbits or moles. - Boat, on the other hand, is a man-made object used for transportation on water, not related to any animal-specific habitat. Thus, Boat is the odd one out. Therefore, the correct answer is 4 . Quick Tip When identifying the odd one out, consider the category each item belongs to, such as habitats or structures related to animals vs. inanimate objects.
