Angelique's psychology teacher, Mrs. Schmidlap, always makes students get out of their seats to participate in demonstrations. Today was Angelique's turn. Mrs. Schmidlap had Angelique face the class, close her eyes, and touch her fingers to her nose. Angelique was so nervous and embarrassed that she forgot to ask what the demonstration was supposed to show.
What was Mrs. Schmidlap trying to show her class by using Angelique?
