This question is looking for the statement which most weakens or undermines the argument, which in this case is the advisability of implementing the Health Advocate's Argument. A very effective way of weakening an argument is to target and weaken it's assumption.
Let us take a closer look at the argument and divide it into sections.
Claim:
The implementation of mandatory calorie counts on all restaurant menus is widely seen as an effective measure to combat obesity.
Premise:
Studies have shown that when calorie information is readily available, people choose healthier options.
Conclusion:
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.
An assumption is the crucial unstated link of an argument that needs to be true in order for the argument to hold up
. It often acts as the link between the premise and the conclusion.
So in this instance we can summarise the Health Advocate's Argument as "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"
The question asks "Which of the following, if true, most seriously calls into question the
advisability of implementing the proposal?", meaning which statement most seriously undermine's the heart of the Health Advocate's Argument.
Let's look at the answer choices.
(A) Many restaurants that voluntarily provide calorie counts have seen a decrease in customers, indicating potential revenue losses for businesses.
If we look at advisability of implementing the proposal, this is a pretty severe drawback. A decrease in customers means the customers will not see the caloric values of food, which will not help them from a health perspective. Moreover, harming the profitability of many restaurants in the process, since it is outlined in the plan that
all restaurants should be
required to display calorie counts is a huge hit to the restaurant industry on a national level. Not advisable.
(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 does not really undermine the argument as there is the possibility that if the same study was done on other restaurants, it would also yield similar positive results.
(C) Restaurants that have already implemented calorie counts report difficulties in accurately estimating the calorie content for every dish, leading to frequent revisions.
This seems like a slight inconvenience for the restaurants but does not undermine the effectiveness of the plan. We do not know what the net benefit is of implementing the plan as a whole so cannot say.
(D) Foods that are high in calories are often the most affordable options, making them more appealing despite calorie count displays.
Being more appealing does not mean automatically that people will go for that. They could still be appealing but people could be opting for healthier alternatives.
(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 does not strongly undermine the plan. It can also be argued that many foods that do not have high-calorie counts are healthy. We are not going to quantify the nutritional value of every single food with respect to its caloric content. The word "many" is also vague. Even with the many foods that are unhealthy with a low-calorie count, people could still be having positive effects from the implementation of the plan.
Answer is A.
