Since the Fall of 2012, Public Schools Have Had to Meet

Since the fall of 2012, public schools have had to meet new nutrition standards (which included offering more fruits and vegetables) for their lunches. In 2013, the USDA (United States Department of Agriculture) reviewed data from the 2005 School Nutrition and Dietary Assessment to investigate whether students in schools that were already following the new standards (school group A) ate more fruits and vegetables than students in schools that were not following the new standards (school group B) .
You will be presented with some of the overall findings of the review and will then be asked questions related to these conclusions.
-Finding #1: If schools offered greater amounts of fruits and vegetables, then more students ate them. However, many students in both schools did not did not eat any fruits and vegetables. This suggests that

A) offering more fruits and vegetables increases the chances that students will eat them, but simply offering more may not be the only solution to bettering child lunch nutrition.
B) a lower amount of fruits and vegetables should be offered to students in both school group A and school group B.
C) offering more fruits and vegetables decreases the chances that students in school group B will eat them but increases the chances that students in school group A will eat them.
D) offering more fruits and vegetables increases the chances that students will eat them but only if they have all essential vitamins and minerals.
