问题     Taste is such a subjective matter that we don’ t usually conduct preference tests for food. The most you can say about anyone’ s preference, is that it’ s one person’ s opinion. But because the two big cola(可乐饮料)companies--Coca-Cola and Pepsi Cola are marketed so aggressively, we’re wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting.
    We invited staff volunteers who has a strong liking for higher Coca-Cola Classic(传统型)or Pepsi, Diet(低糖的)Coke, or Diet Pepsi. There were people who thought they’d have no trouble telling their brand from the other brand.
    We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we set them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participant’ s choices with what mere guess-work could have accomplished.
    Getting all four samples right was a rough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse--only 7 of 27 identified all four samples correctly.
    While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so fatigue, or taste burnout, was not a factor. Our preferences test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.
According to the passage the preference test was conducted in order to ______.
选项 A、find out the role taste preference plays in a person’s drinking
B、reveal which cola is more to the liking of the drinkers
C、show that a person’ t opinion about taste is mere guess-work
D、compare the ability of the participants in choosing their drinks
答案A
解析 本题问的是进行偏好测试的目的。文章中第一段最后两句说“．．we’ve wondered how big a role taste preference actually plays in brand loyalty．We set up a taste test．．．in a blind tasting．”所以正确答案应为A“弄清口味在个人选择什么饮料时起什么作用”。
