Answer: Wendy's schema of how a typical beach looks includes shells
Explanation: The psychological concept of a scheme implies that a particular image of something according to the scheme should look a certain way. This actually means that the brain connects a certain knowledge or experience to a particular event or object, subject, etc. Based on a certain knowledge or experience, one approaches a meaningful, known scheme, leading to known actions. So Wendy draws a picture of a beach with shells based on her beach experience or some previous beach image and approaches drawing with an understanding of the beach she already has.
