John Garcia and his colleagues, as a result of their studies, came to conclude that the cancer patients who experienced nausea after treatments developed a taste aversion to the foods they had eaten earlier. The technique they developed for minimizing this negative effect involved:
A. flashing different pictures of a patient's favorite food on an overhead monitor while the patient underwent treatment.
B. giving a patient unusual foods, such as coconut or root-beer flavored candy, at the end of their last meal before undergoing treatment.
C. administering food to a patient in the middle of the treatment cycle.
D. telling a patient to eat samples of favorite foods before entering therapy, thereby ensuring that the patient remembered what the favorite foods were even after treatment.
