Five people - P, Q, R, S, and T - have different pets: a dog, a cat, a bird, a fish, and a rabbit. P has a dog, Q has a cat, R does not have a fish or a rabbit, and S has a bird. What pet does T have?
Answer: D. Rabbit
Since P has a dog, Q has a cat, S has a bird, and R cannot have a fish or a rabbit, T must have the rabbit.
