Answer:
B. could not remember how to demonstrate it without reinforcement is the correct answer.
Step-by-step explanation:
Edward Tolman was an American psychologist and professor at University of California in Berkley. He founded the purposive behaviorism branch of psychology through his studies, which usually involved rats and mazes. Tolman was considered and stimulus-stimulus theorist, so he argued that animals didn't need any biologically significant event to learn. The question refers to an experiment where Tolman and some colleagues put some rats in a maze, and they could find the solution more quickly when there was food involved as a reinforcement. When there was a lack of food, the rats took longer, so letter B is the correct answer.
