Nutritionist Claim: It has been proposed that to combat rising obesity rates among teenagers, schools should strictly regulate the snack options available in school cafeterias. Critics argue that teenagers will just bring less healthy snacks from home if they want them. However, a recent study shows that the average consumption of unhealthy snacks by teenagers at school is less than two items per week, suggesting that teenagers do not heavily consume these products at school anyway. Thus, regulating school cafeteria offerings would not significantly impact overall teenage snack consumption.
Here it is stated that:
There is a proposal to regulate snack option in school cafeterias. However study shows the consumption of unhealthy snacks is comparatively lesser. Thus, regulation wont have any impact.
Which of the following, if true, would most seriously call into question the nutritionist's conclusion?
A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school.
This statement deviates from the argument about regualtion of snacks at school.
B. Many schools already limit the sale of certain types of unhealthy snacks, but they remain available through vending machines not controlled by the cafeteria.
Here too, vending machines is not in the context of argument.
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
Here again, this provided a suggestion but does not calls into question the argument in hand.
D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
Now, this does calls into argument as it attacks the argument. If the study measured only during hours, there are high chances that the students would consumer unhealthy meals after or before shcool. Hence this the answer.
E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
This statement given a reason for teenagers having meals at school hours, but does not question the argument. In fact in it it is already stated that teenagers dont have often meanl during school hours.
