­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.

­Nutritionist's conclusion: Regulating school cafeteria offerings would not significantly impact overall teenage snack consumption.

Correct choice: E

This statement says that skipping meals at home might be the reason of having unhealthy/healthy snacks at school. But according to the nutritionist regulating snack options will not help significantly but according to this statement regulating will be beneficial as students will be having only healthy snack options at school.

Incorrect choices:

A: This actually strengthens the nutritionist's conclusion.

B: If any how students are getting unhealthy snacks at school then this statement strengthens the nutritionist's conclusion.

C: If Health Education classes can influence students to eat healthy snacks then this will reduce the impact of school regulations and will support nutritionist's conclusion.

D: This is irrelevant as it doesn't relate with significance of regulating school cafe.

­(A) Teenagers consume more unhealthy snacks at home if options are lacking at school: This strengthens the argument for regulation. If unhealthy options are readily available at school to compensate for a lack of desirable choices, it weakens the study's findings. Eliminate (A).

(B) Vending machines sell unhealthy snacks: This highlights a limitation but doesn't directly address the study's findings on cafeteria consumption. Eliminate (B).

(C) Health education can influence choices: This doesn't affect the study on current consumption levels. It's a separate factor influencing healthy choices. Eliminate (C).

(D) Study didn't consider snacks outside school hours: This directly weakens the conclusion. The study might underestimate total unhealthy snack consumption if it only considered school hours. This is a significant limitation.

(E) Teenagers skip meals at home, increasing snacking: This doesn't necessarily mean they snack more on unhealthy options. It could be any type of snack. Eliminate (E).

So ans is D

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 is correct choice as regulation in cafeteria would result high snack consumption at home which is not in line with claim of nutritionist)

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. (out of scope as we are concerned with cafeteria regulations)

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 - health education classes may have any effect but we are only concerned with the effect of cafeteria regulations)

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school. (Slightly strengthen the conclusion as the study measured the snack consumption within school hours which is mentioned less by nutritionist)

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. (Still consumption of unhealthy snacks is low and thus cafeteria regulations have no significant effect on consumption of unhealthy snacks)

­To find an option that would most seriously call into question the nutritionist's conclusion, we need to determine that the study conducted is either inappropriate or incomplete.

Let's analyse each option now:
A. Consumption at home is out of scope as the study is only concerned for consumption at school. Eliminated.
B. This option is completely agreeing with the main conclusion of the argument that regulating school cafeteria offerings would not significantly impact overall teenage snack consumption. Thus it supoorts it and not questions it. Eliminated.
C. If after health education classes, suppose snack consumption goes down in the school, that will be because of the classes and not the regulations on cafeteria. Eliminated.
D. Now this option, clearly tells us that the study is incomplete as it does not consider consumption from cafeterias right before and after the school hours but only in the school hours. Hence, calling the conclusion into question which means that regulating cafeterias will certainly reduce unhealthy snack consumption in school.
E. This option is generally talking about both type of snacks healthy as well as unhealthy whereas we are concerned with only unhealthy ones. Eliminated.

Therefore, the answer is option (D).

We are looking for a statement that weaken the nutritionist's conclusion ::  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.Strenghthens the conclusion.

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.Irrelavant. 

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings. OFS

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.Hmm, If the study is limited all our conclusions are shattered. So it acts as a -ve statement. 

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.Irrelavant. 

Hence IMO 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.

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.

Now for the Nutritionist's conclusion, He critisizes the idea of regulating the options at school cafeteria and concludes that it would not impact the overall (Everywhere, even at homes) teenage snack consumption. So we have to figure out the option which would question/ weaken the nutitionists conclusion.

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.
Now if the teenagers start to consume more at home when they don't find options at school, THIS WILL IMPACT THE OVERALL TEENAGE SNACK CONSUMPTION AS THEY WOULD START EATING MORE 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. Supports the conclusion.

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings. Doesn't have anyhting to do with the offerings and 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 critisizes the study but not the conclusion, and we need to prove that the decision would have an impact and this option does not help for it.

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. This is a neutral answer and hence does not calls the conclusion in question.

Conclusion -> 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. Correct Choice
This choice casts doubt on the derived conclusion as even though the average consumption of unhealthy snacks by teenagers at school is less than two items per week, they may start consuming unhealthy snacks at home and this will 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. Wrong Choice
This choice doesn't impact the conclusion. If unhealthy snacks remain available through vending machines that are not controlled by the cafeteria, regulating cafeteria offerings would not impact 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. Wrong Choice
Not Relevant

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school. Wrong Choice
This choice or the premise in the argument doesn't state that students buy snacks from cafeteria for consumption before or after school. Not Relevant

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.­ Wrong Choice
Not Relevant

­Question stems tells us,
Proposal - to combat rising obesity rates among teenagers -> regulate the snack options available in school cafes
Critics argument - teenagers will just bring less healthy snacks from home
Nutritionist argument - average consumption of unhealthy snacks by teenagers at school is less than two items per week so teenagers do not heavily consume these products at school
Nutritionist conclusion - regulating school cafeteria offerings would not significantly impact overall teenage snack consumption

We need to weaken Nutritionist conclusion.

Looking at options- 

A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school.
This provides additional support to nutritionist's conclusion that regulating school cafeteria offerings would not significantly impact overall teenage snack consumption as they are more likely to ocnsume unhealthy snacks at home if no options are available at school. 
Eliminate

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.
This does not necessarily invalidate the conclusion. We do not know how much is 'certain'. We need to assume for this statement to have effect on conclusion. Eliminate

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
Out of topic. Not mention of health education classes or how they will affect ban of certain unhealthy snacks. Eliminate

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 could work. If study overlooked time when teenagers consumed unhealthy snacks, we can question the conclusion that is dervied from the study. So, maybe unhealthy food consume is higher among teenagers than noted in study as study was flawed. Keep it

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
Snack consumption could be important than nutritionist has claimed in question but it doesn't directly challenge the conclusion that regulating school cafeteria offerings would not significantly impact overall teenage snack consumption. Eliminate­

I will go with option D.

We have to weaken the conclusion that regulating school cafeteria offerings would not impact overall teenage snack consumption.

The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school

Now let us suppose Rahul bought 10 snacks everyday from cafeteria, but in school in a week he is eating only 2, but after the school he is eating more of it, which is impacting. So regulating will be important.

Option Elimination :

A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school. -> In a way strengthening, so not our answer.

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. -> Not weakening the conclusion, not our answer.

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.

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. -> Not stating that even if there is likelihood why the consumption is still less in school. Not weakening perfectly.

So OA = D

A - strengthens the claim that regulating school cafeteria offerings would not significantly (positively)impact overall teenage snack consumption - if anything, it would increase their snacks consumption.

B - if this were true, and the study shows that students consume, on average, only two snacks per day - then option B will further strengthen the nutritionist's claim: Regulating only cafeteria food will not have any impact on the snack consumption.

C - out of scope

D - if this were true, the study reveals only a part of the snack consumption - the students could be consuming way more snacks than accounted for. Weakens claim.

E - strengthens claim.


OPTION D

A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school.
This option does not bring nutritionist conclusion in doubt, if this were to be our stand in arguing with the nutrition, he'd have the take that just because teenagers are eating unhealthy at home because we don't provide it here, doesn't mean we should provide it here.

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.
This is factual but still irrelevant to the nutritionist's conclusion and with our stand to weaken it.

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
This, if anything, bolsters nutritionist's claim that no change in cafeteria regulations and offerings is required.

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
This also, bolsters nutritionist's claim, since that's what the study was bound to measure, to see the stats on consumption of unhealthy food during school hours.

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
This is the best stand the we can have to weaken nutritionist's conclusion, although teenagers only consume less than two unhealthy snack items during school hours, if they can't do it at home, if goes unchecked, as the nutritionist suggests that it can be allowed to, teenagers will do it at school instead.

Ans ) A
As it challenges nutritionist claim to combat obesity, as students consume unhealthy snacks at home , regulation at school wont help

B) Availabity of unhealty snack strengthens nutrionist claim
C) Health education class, not discussed in passage
D) The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school, but we have to call into question of nutritionist conclusion, which is to regulate schools snack options
E) Skip meals, irrelevant

­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.

­Certainly!

A. Option A suggests that if unhealthy snacks are not available at school, teenagers might compensate by consuming more of them at home, thus impacting overall consumption negatively. Still, it does not address how regulating school cafeteria offerings would significantly impact teenage snack consumption.

B. Option B indicates that even if school cafeterias restrict unhealthy snacks, vending machines outside cafeteria control still provide access, potentially undermining the impact of cafeteria regulations.

C. Option C proposes that school health education could independently influence teenagers to make healthier snack choices, potentially reducing the impact of cafeteria regulations.

D. Option D highlights a limitation of the study, suggesting that it may have underestimated total unhealthy snack consumption by not considering snacks consumed immediately before or after school.

E. Option E suggests that teenagers skipping meals at home might increase their consumption of snacks during school hours, whether healthy or unhealthy, potentially influencing overall consumption patterns.
Option E directly challenges the assumption that regulating school cafeteria snacks would have little impact on 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: supports the conclusion 

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: supports the conclusion 

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: the data might be skewed ; questions the data used for study

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours. affects the claim . attacks the premise

A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school.
This idea does not question the expert and the reason is that the critics say that the fosters bring healthy food from 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.
The expert has already said that schools should be strictly controlled so that unhealthy food is not served in the cafeteria.

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
The expert suggested stricter controls on foods served in school cafeterias, not health education classes that discuss dietary choices.

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
This idea is an answer because if students have a healthy diet inside and outside of school, they will not be overweight, so the expert thinks that the study should not only measure the snacks they eat in school.

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
This idea is not related to the opinion of experts and critics
Both groups did not say that the students skip food at home

therefore the answer is D

A. Teenagers are more likely to consume unhealthy snacks at home if they perceive a lack of desirable options at school. #Further supports nutritionist

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 detail

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings. #alternate healthy options does not affect argument

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school. #even if school snacks can be reduced, obesity can reduce

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.#Correct. If ttens skips meal & eats snacks at school, they can bcome obese. so regulating snack will force them not to eat snacks at chool, reducing obesity

­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.
Explanation: This statement suggests a possible outcome based on perceived behavior changes but does not directly address the study's findings or its limitations. However, it challenges the nutritionist's conclusion indirectly by speculating on potential behaviors. INCORRECT

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.
Explanation: This option points out a potential loophole in the regulation but does not directly address overall consumption patterns. It suggests that students might still access unhealthy snacks despite cafeteria regulations, but it doesn't provide a direct argument against the nutritionist's conclusion about overall consumption. INCORRECT

C. Health education classes that discuss dietary choices can influence teenagers to make healthier eating decisions, independent of the school cafeteria offerings.
Explanation: This option suggests an alternative method for influencing healthy eating, but it doesn't directly undermine the conclusion that regulating cafeteria offerings would not significantly impact overall consumption. INCORRECT

D. The study measured only the snacks consumed within school hours and did not account for additional consumption immediately before or after school.
Explanation: This statement directly addresses a methodological issue with the study's data and provides a stronger basis for questioning the nutritionist's conclusion. By pointing out that the study did not account for snack consumption outside of school hours, it directly questions the validity and reliability of the conclusion drawn from the study. CORRECT

E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.
Explanation: This option suggests that teenagers who skip meals at home may consume more snacks during school hours, which could imply that school snacks play a significant role in their diet. However, it does not provide a direct contradiction to the study's findings that the average consumption of unhealthy snacks at school is less than two items per week. INCORRECT

The Correct answer is D

Conclusion: regulating school cafeteria offerings would not significantly impact overall teenage snack consumption

Premise: the average consumption of unhealthy snacks by teenagers at school is less than two items per week

Which of the following, if true, would most seriously call into question the nutritionist's conclusion?

Now, consider, E. Teenagers often skip meals at home, which increases their likelihood of consuming snacks, both healthy and unhealthy, during school hours.

So, if the statement E is true and thus regulations are being placed on school cafeteria, certainly nutritionist's conclusion would most seriously call into question.

Answer: E.
