Activity 1: Which of the following does not fit a prototype of fruits?
A. Banana B. Orange C. Coconut D. Apple
A prototype is a member of the natural concept that possesses all or most of its distinguishing

on trees, they are sweet, they have peels, and seeds. Although a coconut grows on trees, it is not a
prototypical fruit because it lacks other defining features of fruits. Therefore, option C is the correct answer.
