What is the therapy that can be applied to the broadest range of patients

Matthew used to like strawberries and tried some frozen strawberry daiquiris one night. After the sixth daiquiri, Matthew became extremely ill. Now Matthew finds that even the smell of strawberries can make him feel nauseated. In this example of classical conditioning, the unconditioned stimulus is:

a. the illness that followed the sixth strawberry daiquiri b. the strawberry daiquiris that Matthew consumed c. the smell of strawberries d. the nausea that Matthew feels when he smells strawberries

You encounter four battery-powered toys moving in a small corral. Each toy is a made up of multiple parts: a car in which four figures are riding. All the parts for each toy are the same color, and each toy has its own distinct color. One toy is pink, one is blue, one is green, and one is red. Use gestalt laws of perceptual grouping to explain how your brain recognizes the figures that make each toy as a distinct whole.
