To determine which option most seriously calls into question the advisability of implementing the proposal for mandatory calorie counts on restaurant menus, we need to identify the option that undermines the effectiveness or the practicality of the proposal.

Let's analyze each option:

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.

This option suggests that implementing mandatory calorie counts could harm businesses by reducing their customer base. While this may be a concern for businesses, it does not directly challenge the effectiveness of the measure in reducing obesity.

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry.

This option highlights a limitation in the studies cited by the health advocate. If the studies mainly focus on fast food restaurants, the results may not be generalizable to all types of restaurants. This calls into question whether the proposed measure would be as effective in reducing obesity across the entire restaurant industry.

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.

This option points out a practical challenge in implementing the proposal. If restaurants struggle to provide accurate calorie counts, the reliability of the information could be compromised. However, this does not directly address the overall effectiveness of calorie counts in influencing healthier choices.

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.

This option suggests that even with calorie counts, people might still choose high-calorie foods due to their affordability. This directly challenges the assumption that calorie information alone will lead to healthier choices and reduce obesity.

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.

This option indicates that calorie counts might not provide a complete picture of a food's healthiness. People might choose low-calorie options that are still unhealthy due to high salt or sugar content, undermining the goal of reducing obesity.

The option that most seriously calls into question the advisability of implementing the proposal is:

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.

This option challenges the core assumption that calorie information will lead to healthier choices by suggesting that economic factors might override the influence of calorie counts.

Health Advocate's Argument: The implementation of mandatory calorie counts on all restaurant menus is widely seen as an effective measure to combat obesity. Studies have shown that when calorie information is readily available, people choose healthier options. Therefore, a health official proposes that all restaurants should be required to display calorie counts, aiming to reduce the national obesity rate within 10 years.

Which of the following, if true, most seriously calls into question the advisability of implementing the proposal?

Line of thought: If people see calorie counts, eat less calories counts -> obseity will decrease, though what if less calorie has actally more sugar???

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses. -> we aren't concerned with revenue loss 

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry. -> This might feel like a trap option, though if it effective for fast-food, it doesn't mean it won't be effective for other restaurants, it is a bit vague. 

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions. -> So? Stil irrelevant

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays. -> Irrelevant, it says people prefer healthier options over high calorie, so we can skip this

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.­ -> Attacks perfectly (Answer)

Type of Question: Weaken

Scenario:

In cases where Calorie count is displayed people chose Healthier options.
So displaying calorie count can make people become healthy & hence reduce obesity rate.


Pre-thinking:
When High density food like cottage cheese can be healthy. Similarly, What if lower calorie food is not always healthy??


Ans. E goes in same line that sugar & salt in low calorie food might again lead to health issues.
Hence E is the answer.

A weakens business scenario not argument at question.
B focuses on limitation of study but not necessarily Argument weakner.
C talks about accuracy but calorie measure is tentative indicator. So eliminate.
D is contradicting study find hence not correct ans.

IMO - B
(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses. // Eliminate - Irrelevant focus is on reducing obesity not on business.


(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry. // Correct - because shows the insufficient data to conclude that everyone should implement the calorie count system.


(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions. // Eliminate - It does not challenge the conclusion

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.// Eliminate - Trap answer but with this information we cannot judge whether obesity will increase or decrease or stay the same

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone. // Eliminate - Irrelevant because argument is about obesity and not healthiness of the food.

­Since the text gave us the cue that the way to combat obesity focuses solely on calorie counts. So we have to choose an answer that argues that calories alone is not the indicator of healthy food. I chose E since it implies that calorie information alone may not lead to healthier choices overall, and that the food's calories maybe low but they still can make people obesed. Other answers are irrelevant since they mentioned drawbacks of implementation but not call into question the advisability of implementing the proposal.

Implementation of calorie counts doesn't guarantee health hygiene because other foods with low calorie may be very unhealthy, hence the implementation of this calorie count is not advisable.

this is true , but not a solid weakener

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.

same as option B not a serious weakener

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.
this does not solve purpose of weakening the conclusion 

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.
 this is an alternate reasoning and does weaken the conclusion 

OPTION E is correct

Conclusion: all restaurants should be required to display calorie counts, aiming to reduce national obesity rate within 10 years
because
­ Implementation of mandatory calorie counts on all restaurant menus is widely seen as effective measure to combat obesity.
Studies show that - when calorie information is readily available, people chhose healthier options

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.
-- this lays doubt on implementation of the scheme as it indicates potential revenue loss. but it does not touch on logic of people eating healthier options when displayed calorie

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry.
-- It lays doubt on studies focusing on fast food restaurants.. even though small portion of industry benefits and aims to reduce national obesity is good enough. so out

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.
-- it is about implementation issue as restaurant find difficulty in implementing calorie content . so out

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.
-- It says even though we display calorie content , high calorie are most affordable ones and appealing. So it does lay doubt on reducing national obsesity however it does not touch logic of calorie in making healthier decision as it points out on affordability side. so out

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.
-- it talks about unhealthy stuff not reflected in calorie counts and hence people still consume unhealthier options and may not reduce national obesity.
So E is the answer

The answer is D.
For C, it is mandatory to apply calorie counters, so it can't be an excuse that it has to be revised frequently.
A and B do not seem so appropriate, while in E, the calorie count is also for salt and sugar, so it will not be an issue.
In D, it can be the driving factor for the failure of this proposal that the high-calorie foods are, in general, cheaper.

­(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.
It shows a concern regarding decreasing customer base or revenue for restaurants. Since all restaurants are going to display calorie counts, customers will not have other options. 
Moreover, it doesn't directly challenge the proposal's effectiveness in reducing obesity rates.


(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry.
It shows that limited applicability of the plan, however it doesn't directly dispute the core argument that calorie counts lead to healthier choices and reduced obesity.

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.
It highlights  challenges in implementation but it doesn't directly dispute the core argument that calorie counts lead to healthier choices and reduced obesity.

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.
This statement directly challenges the core argument by suggesting that despite calorie counts, people might still choose high-calorie options due to affordability, thus undermining the proposal's effectiveness in reducing obesity rates. Customers will still go for calorie rich foods due to affordability.

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.
This statement raises a valid point about the limitation of calorie counts in reflecting overall healthiness, but it doesn't directly dispute the core argument that calorie counts lead to healthier choices and reduced obesity.

Let's evaluate each option while keeping in mind the objective, which is to combat obesity:

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.

-> This talks about financial impact, not the effectiveness of showing calorie counts so we can ignore this option.

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry.

-> This tells us that the study supporting the proposal might not be universally applicable, but it doesn't necessarily undermine the goal of reducing obesity (as it will still play a role in that sector) so this is not the answer we are looking for.

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.

-> This is an operational/implementation issue, but it is unrelated to the effectiveness of showing calorie counts so we can ignore this option as well.

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.

-> This implies that the users might not deviate from selecting high-calorie foods despite the calorie count display, which means that the proposal might not be effective. This calls into question the advisibility of implementing the proposal. Furthermore, it adds information which directly contradicts that "studies have shown that when calorie information is readily available, people choose healthier options" - a basis for the proposal. This is the correct answer.

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.

-> This, while it does call into question the advisibility of implementing the proposal, does so through the lens of overall "health" and not necessarily obesity. It does not challenge calorie counts' link to obesity so it is not the strongest option.


The answer is D imo.­

­Health Advocate's Argument: The implementation of mandatory calorie counts on all restaurant menus is widely seen as an effective measure to combat obesity. Studies have shown that when calorie information is readily available, people choose healthier options. Therefore, a health official proposes that all restaurants should be required to display calorie counts, aiming to reduce the national obesity rate within 10 years.

Which of the following, if true, most seriously calls into question the advisability of implementing the proposal?

Assumption: People are obese because they eat at these restaurants or anything on similar lines.

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.
Restaurants of this kind may come up with other innovative ideas or advertisements, as they usually do, to increase their business and thrive. Hence, health advocate's argument is not questioned and still very much valid.

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast-food restaurants, which only represent a portion of the restaurant industry.
If we implement the plan then obesity resulting from these fast-food restaurants would still reduce compared to the current obesity level. Therefore the plan would still work and B does not weaken the argument.

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.
Options C and E are both incorrect for the same reason. Both target difficulty while counting the number of calories, which is not the main concern of the author.

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.
If this shred of information is taken to be true, the chances, of the implemented plan succeeding, reduce. So, we can conclude that D questions the given argument.
CORRECT

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.
Options C and E are both incorrect for the same reason. Both target difficulty while counting the number of calories, which is not the main concern of the author.

­Should be B.

Premise: 
1. The implementation of mandatory calorie counts on all restaurant menus is widely seen as an effective measure to combat obesity
2. Studies have shown that when calorie information is readily available, people choose healthier options

Conclusion: all restaurants should be required to display calorie counts, aiming to reduce the national obesity rate within 10 years

A. is irrelevant. We don't care for "revenue losses for businesses". Out.
B is relevant. B talks about the limitation of "calorie counts". B casts doubt on the conclusion. Keep.
C. is relevant to "calorie counts", but C talks about the difficulties in implementing the calorie counts. Even if the plan is difficult to implement, it can still achieve the intened result "reduce obesity". Out.
D. "affordable" is irrelevant. We don't care for the price. We care for the effect of the plan. Out.
E. is uncertain. It mentions "many". But how many? It also mentions "which is not necessarily reflected in calorie counts alone". But when can high salt or sugar content be reflected in calorie count? Out.

­Health Advocate's Argument: The implementation of mandatory calorie counts on all restaurant menus is widely seen as an effective measure to combat obesity. Studies have shown that when calorie information is readily available, people choose healthier options. Therefore, a health official proposes that all restaurants should be required to display calorie counts, aiming to reduce the national obesity rate within 10 years.

Which of the following, if true, most seriously calls into question the advisability of implementing the proposal?

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry.

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone.

­To assess the advisability of implementing mandatory calorie counts on all restaurant menus, we need to consider potential challenges or drawbacks that could undermine its effectiveness. Let's evaluate each option:

(A) If mandatory calorie counts lead to decreased customer traffic and revenue loss for restaurants, this raises significant economic concerns. It suggests that the implementation could have adverse effects on businesses, potentially outweighing the benefits of combating obesity. This option seriously calls into question the advisability of implementing the proposal because economic impacts could deter restaurants from complying.

(B) This option suggests a limitation in the applicability of studies to other types of restaurants. While it raises a consideration about generalizing effectiveness, it doesn't directly challenge the core effectiveness of calorie counts in influencing consumer behavior. This option does not seriously call into question the advisability of the proposal as it focuses on the scope of existing studies.

(C) While this highlights operational challenges, it doesn't necessarily undermine the core effectiveness of calorie counts in influencing consumer choices or combating obesity. This option does not seriously call into question the advisability of the proposal.

(D)  This option points out a behavioral aspect where affordability may override health considerations, potentially limiting the impact of calorie counts on consumer choices. If affordability undermines the influence of calorie counts on food choices, it could challenge the effectiveness of the proposal.

(E) This option underscores a limitation of calorie counts in fully informing consumers about the healthiness of foods. If consumers make choices solely based on calorie counts, they may overlook other unhealthy aspects of foods.This option raises concerns about the comprehensiveness of calorie counts but does not directly call into question the advisability of the proposal.

Among the options provided, option (A) most seriously calls into question the advisability of implementing mandatory calorie counts on all restaurant menus. If calorie counts lead to significant revenue losses for restaurants, it could deter compliance and potentially outweigh the benefits of combating obesity. Therefore, option (A) is the most critical in challenging the proposal's advisability.

mandatory calorie counts will lead to healthier food choices, thereby reducing the national obesity rate within 10 years

A) Irrelevant

B) Intersting trap. Although sample of study is only fast food Restaurants, we can't weaken that implementation of the plan will reduce obesity in 10 yrs

C) If calorie values are inaccurate, this would weaken the conclusion

D) calorie counts alone may not be sufficient to influence food choices because affordability. Decieving choice but not weakening the conclusion

E) Irrelevant

(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses: doesn't affect the proposal 

(B) Studies demonstrating the effectiveness of calorie counts have primarily focused on fast food restaurants, which only represent a portion of the restaurant industry: the proposal can still work 

(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions: points out practical challenges in implementing the proposal

(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays: directly challenges the proposal as it may be the case that higher calorie options are affordable and so even putting a calorie count will not refrain the people from purchasing the dish 

(E) Many foods that do not have high-calorie counts are still unhealthy because of high salt or sugar content, which is not necessarily reflected in calorie counts alone: talks about which calorie count .
