Marie is 2 years old and has a dog that is always friendly, so she thinks all dogs are like that. while she was out walking, a barking dog came up to her and scared her. now she knows not all dogs are friendly. this would be an example of: a. concept reduction. b. assimilation. c. accommodation. d. schemas.

The answer is Accomodation.

In Piaget's theory of cognitive development, he announces two phases in the learning process, assimilation and accomodation. While assimilation refers to adding new ideas and knowledge to the already existing one, accommodation refers to shaping the existing knowledge and schemas to deal with a new object or situation.

In this case, Marie already had knowledge about dogs, however by encountering a dog that didn't fit the idea she had them, she had to reshape that idea, therefore, it is an example of accommodation.
