Last year a chain of fast-food restaurants, whose menu hadalways centers on hamburgers, added its first vegetarian sandwich, much lower infat than the chain’s other offering. Despite heavy marketing, the newsandwich accounts for a very small proportion of the chain’s sale. Thesandwich’s sales would have to quadruple to cover the costs associated withincluding it on the menu. Since such an increase is unlikely, the chain wouldbe more profitable if it dropped the sandwich. Which of the following, if true, mostseriously weakens the argument? (A) Although many of the chain’s customershave never tried the vegetarian sandwich, in a market research survey most ofthose who had tried it reported that they were very satisfied with it. (B) Many to the people who eat at thechain’s restaurants also eat at the restaurants of competing chains and reportno strong preference among the competitors. (C) Among fast-food chain in general, therehas been little or no growth in hamburger sales per the past several years asthe range of competing offerings at other restaurants has grown. (D) When even one member of a group ofdiners is a vegetarian or has preference for low fat food, the group tends toavoid restaurants that lack vegetarian or low-fat menu options. (E) An attempt by the chain to introduce alower-fat hamburger failed several years ago, since it attracted few newcustomers and most of the chain’s regular customers greatly preferred the tasteof the regular hamburgers.
我选的是A。
