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?
A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options 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.
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
Conclusion -
Regulating school cafeteria offerings would not significantly impact overall teenage snack consumption.Weakener will be anything which shows - Regulating school cafeteria offerings may / would 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. ==> Hence regulating cafetria wont help. They will anyways eat at home if controlled at school. REJECTED.
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. ===> Hence , again , regulating cafetria wont help. Those vending machines will play the spoilsport. REJECTED.
C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings. ===> Hence , again , regulating cafetria wont help as the children are more likely to be influenced by the health education classes. REJECTED.
D.The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school. ==> This option identifies a flaw in the study. Children may consume unhealthy food before the classes begin or after the classes get over. Reminding us of our own school days ,
D is my answer as it shows that regulating cafeteria may help.
D is my answer.E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. This option is wrong because we dont know the corresponding proportion of healthy and unhealthy food that children are likely to consume. If they are more likely to consume healthy food , then regulating cafetria will NOT help. REJECTED.
