If revenue from veg sandwich is lower than cost , the only way to bump up the revenue is to increase the sale . When sales increase to at least a level where revenue atleast equals to the cost , then veg sandwich will atleast not cause any loss and the restaurant can just take away the same profit without dropping the veg sandwich.

(D) says , if atleast one member prefers veg in group , may be for the sake of friendship everyone opts for veg , then this options suggests that for on's preference atleast 2 customer will buy a veg sandwich. Well , this certainly boosts sales a bit or atleast increases the chance of it.

Hence D is the answer

D for me too.as it indicates from 1 customer the whole group would start eating and slowly sales would grow

Option "E" is also a contender but "attracted few new customers" makes it unlikely to increase the profit of the company.

D wins.

Hi , Can someone help with why A is not a contender. If people are satisfied , they will keep buying it. And the firm will be at least as profitable as it is now or even more with word of mouth publicity.

D for me too ... The conclusion that dropping it makes the most sense is suffers maximum impact via D

OA is out of scope since you cannot contest the supporting arguments to weaken the argument rather you attack the conclusion to weaken the argument.

Hi! Karishma,

Consumers reported that they were satisfied, but it doesn't mean that they will go and eat the sandwich again

The profit of the chain is not just becuase of sandwhich but also from selling other items. Option a does not gaurantee that people will be buying other items.

hi KarishmaParmar the preference does not say that i will come and buy the hamburger. So in most likely no increase in revenue

Hi KarishmaParmar ,

A) Although many of the chain’s customers have never tried the vegetarian sandwich, in a market research survey most of those who had tried it reported that they were very satisfied with it. ------> Another market research surveys may contradict to this report.Overall surveys may not reflect actual impact.But Answer Choice D weakens the argument the most

It took me lot of time to make sense out of D.
Argument says Dropping of sandwich from menu is more profitable.
What if Keeping it on menu is profitable.
D exactly conveys the same , even if the other group members have sandwich or burger ,Overall sale is increased because of sandwich.

please correct me if I am wrong, or I am assuming too much

Option A in a way restates the information given in argument that a small proportion prefer low fat sandwiches. This info does not affect our conclusion and hence doesn't weaken it.

Last year a chain of fast-food restaurants, whose menu had always centered on hamburger, added its first vegetarian sandwich, much lower in fat than the chain’s other offerings. Despite heavy marketing, the new sandwich accounts for a very small proportion of the chain’s sales. The sandwich’s sales would have to quadruple to cover the costs associated with including it on the menu. Since such an increase is unlikely, the chain would be more profitable if it dropped the sandwich.

Type - Weaken
Boil it down - Since sandwhich's sales is unlikely to quadruple , it's removal from menu will be more profitable
Pre- Thinking - Even if the restaurant has not made a break even with respect to sandwhich , we need to find some alternate reason due to which it's increasing the profitability

A) Although many of the chain’s customers have never tried the vegetarian sandwich, in a market research survey most of those who had tried it reported that they were very satisfied with it. Incorrect

B) Many of the people who eat at the chain’s restaurants also eat at the restaurants of competing chains and report no strong preference among the competitors.
Irrelevant
C) Among fast-food chains in general, there has been little or no growth in hamburger sales over the past several years as the range of competing offerings at other restaurants has grown. Irrelevant
D) When even one member of group of diner’s is a vegetarian or has a preference for low-fat food, the group tends to avoid restaurants that lack vegetarian or low-fat menu options.
Correct answer - matches our pre-thinking answer
E) An attempt by the chain to introduce a lower-fat hamburger failed several years ago, since it attracted few new customers and most of the chain’s regular customers greatly preferred the taste of the regular hamburger. Out of scope

Answer D

Option D : When even one member of group of diner’s is a vegetarian or has a preference for low-fat food, the group tends to avoid restaurants that lack vegetarian or low-fat menu options.

The option does not specifically mentions FAST FOOD RESTURANTS , it says restaurants how can one deduce that group of people would visit a FAST FOOD resturant over a regular resturant.....

Guys,

About option D:

without knowing the frequency of customers group with atleast one vegeterian visiting the restaurant ,how can you say that it will weaken the conclusion?
Suppose very few groups with atleast one vegeterian visit the restaurant in a month and they don't bill too much,then how will u make sure maintaining the new sandwich will profit the restaurant?

Even if there is one vegetarian person in a group of 5, other 4 will eat something else. Hence, the overall sales of the restaurant will increase. Hence, it’s actually the veg burger due to which the group is coming to restaurant and the overall sales of the restaurant is increasing .

Hope this helps.....
Help me with a kudos please.....

Which of the following, if true, most seriously weakens the argument?

(A) Although many of the chain’s customers have never tried the vegetarian sandwich, in a market research survey most of those who had tried it reported that they were very satisfied with it. - Trying and liking don't guarantee long-term gain. Doesn't weaken the original sentence

(B) Many of the people who eat at the chain’s restaurants also eat at the restaurants of competing chains and report no strong preference among the competitors.
Not relevant to the argument topic(vegetarian sandwich)
(C) Among fast-food chains in general, there has been little or no growth in hamburger sales over the past several years as the range of competing offerings at other restaurants has grown.
Not relevant to the argument topic(vegetarian sandwich)

(D) When even one member of group of diner’s is a vegetarian or has a preference for low-fat food, the group tends to avoid restaurants that lack vegetarian or low-fat menu options.
Eliminating the vegetarian sandwich will result in a lost business opportunity for other food options and this opportunity(profit) has not been taken into account.
-Weaken the argument

(E) An attempt by the chain to introduce a lower-fat hamburger failed several years ago, since it attracted few new customers and most of the chain’s regular customers greatly preferred the taste of the regular hamburger.
Not so relevant to the argument topic(vegetarian sandwich)
