The conclusion of the nutritionist is : regulating school cafeteria offerings would not significantly impact overall teenage snack consumption, that we should undermine
A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school.
This answer choice says exactly the opposite of the argument, and suggests that regulating will push them to consume unhealthy at home
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.
Irrelevant, because we're dealing with the impact of regulating on unhealthy eating habitudes
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
This is irrelevant to the conclusion
D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
This is correct, if the study is not exhaustive, does not take all the periods students spent at school, then the conclusion may have fallen
E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
But there is no relation with the regulation and its impact on the eating unhealthy habits
Correct answer is D

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.
Which of the following, if true, would most seriously call into question the nutritionist's conclusion?
Prompt explanation: The nutritionist concludes that regulating school cafeteria offerings, to combat rising obesiy rates, would not significantly impact overall teenage snack consumption. The claim gives statistics on snacking during school hours, and behavioral studies of teenager students. The question asks us to choose an option which will weaken 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.
Incorrect: This strengthens the nutritionist's conclusion, that regulating school cafeteria offerings would not significantly impact overall teenage snack consumption.
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.
Incorrect: The study shows average consumption in school, and does not distinguish between vending machines and school cafeteria.
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
Incorrect: This does not question the conclusion, instead it provides another solution and deviates from the critical reasoning as asked by the question.
D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
Correct: If the study skipped snacking before or after school, the nutritionists' conclusion would be based on partial data. This will lead to questioning the substance of the conclusion.
E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
Incorrect: This is still refuted by the study stated.

Answer: A
Conclusion: Thus, regulating school cafeteria offerings would not significantly impact overall teenage snack consumption.
A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school. If snacks are regulated in the school cafeteria, then teenagers are more likely to consume them at home. So there will be a significant impact on overall teenage snack consumption.
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. So even if snacks are regulated in the cafeteria, nothing much changes. So limiting snacks in cafeteria has no impact on overall snack consumption
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings. Out of scope.
D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school. This weakens the study imo, not the conclusion. I don't see how it weakens the conclusion that regulating cafeteria offerings would affect snack consumption.
E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. Regulating snacks will reduce choices for unhealthy snacks. Teens anyways don't each much of those. This option doesn't talk about how the regulation changes anything
