In an experiment that lasted several weeks, volunteers were given either an assortment of snacks or only corn chips between meals. Beforehand, most volunteers predicted that they would be more satisfied with an assortment of snacks rather than just one kind of snack. But afterward, those who received only corn chips reported greater satisfaction. The researchers concluded from this that people tend to mistakenly believe that they prefer variety to monotony in their diets.
Which of the following, if true, would most strengthen the researchers' reasoning?
A. Before the experiment, most volunteers said that corn chips were their favorite snack among those offered.
B. Other researchers have found that variety in diet is more satisfying than variety in other experiences.
C. The volunteers were not informed beforehand that those who did not receive an assortment of snacks would receive only corn chips.
D. The volunteers who received only corn chips were free to eat a wide assortment of foods for their main meals.
E. In a separate taste test, most people found the corn chips to be less appetizing than any other snack the volunteers received.
(E) indicates that most people, if anything, disliked corn chips compared to any other snack that was offered. This means that there was a potential bias AGAINST chips in terms of TASTE. In spite of this, people still reported MORE happiness with chips than with a variety of snacks. This increases the chances that there must have been something ELSE that was the cause for this increased happiness.
