Answer:
It illustrates Piaget's concept of accommodation.
Step-by-step explanation:
According to psychologist Jean Piaget, accommodation happens when we change our schema (ideas) after receiving new information, in order to accommodate it. In the passage, the original schema was that animals that have four legs, fur, and a tail are dogs. However, when new information is presented concerning animals with those same characteristics which aren't dogs, the schema is altered. Now, if an animal has four legs, fur, and a tail and it barks, it is indeed a dog. If it has all that and meows, it is a cat.
