Final answer:
True, not wanting to eat a peanut butter and banana sandwich anymore is an example of taste aversion, a learned response where the brain associates food with illness, even if the two are not directly related. The correct answer is a) True.
Step-by-step explanation:
The statement that not wanting to eat a peanut butter and banana sandwich anymore demonstrates taste aversion is true. Taste aversion is a learned response to eating a food that is followed by unpleasant symptoms, such as nausea or illness. Despite the time lag between eating the food and feeling sick, the brain can associate the two events. Therefore, if you ate a peanut butter and banana sandwich and then fell ill for unrelated reasons, you may still develop a distaste for that particular sandwich, associating it with the illness.
The fact that someone does not want anything to do with a peanut butter and banana sandwich can be considered taste aversion. Taste aversion is a type of conditioning where an individual develops an aversion to a certain food after experiencing negative consequences associated with it. In this case, the negative consequence could be feeling sick after consuming the sandwich. Therefore, the correct answer is a) True.
