Official Solution:
New regulations mandating higher nutrition standards for school meals were introduced with the dual goals of improving children’s overall health and reducing obesity rates. These regulations required that the meals offer a greater variety of foods, including options with lower calorie content, with the ultimate aim of reducing childhood obesity. However, despite implementing these changes, and the fact that many students now purchase their lunches at school, there has not been a noticeable decrease in obesity rates among school-aged children.
Which of the following would, if true, best explain the discrepancy outlined above?
A. Before the new regulations were implemented, most school meals met the nutritional guidelines that were in place at that time.
B. Many students dislike the taste of the healthier entrées and discard them, consuming only small portions of the recommended items.
C. The new regulations mandate that all school cafeterias implement menus in multiple languages.
D. Many schools have expressed concerns with the introduction of new regulations.
E. The increase in food variety makes it harder for students to consistently choose healthier options.
(A) Incorrect: this answer choice does not explain why there was no decrease in obesity rates following the regulations, since the regulations improved nutritional standards.
(B) Incorrect: If students truly ate less at lunch (i.e., discarding food), that could lower total caloric intake—potentially helping with obesity, not worsening it (unless they compensate outside school, but that’s not stated, and we should not bring external assumptions in a correct answer choice).
(C) Incorrect: Irrelevant - the language of the menus would not help explain the discrepancy. If anything, this should have made the menus more relevant to some of the bilingual students.
(D) Incorrect: Schools expressing concerns about the new regulations is not relevant to our augment. As long as the schools are following the regulations, it does not matter if they are concerned or not concerned. Perhaps concerns were about nutrition or perhaps change or perhaps financial concerns - we are not given the context and can't really evaluate this statement properly in its current vague form so it is safe to eliminate it.
(E) Correct: This choice demonstrates a potentially unintended consequence of the new standards, which would undermine their effectiveness looking to reduce obesity. Menu complexity could prevent students from eating healthy and thus would not reduce obesity rates, as students choose higher-calorie options.
