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 is that it’s one person’s opinion. But because the two big cola companies -- Coca Cola and Pepsi Cola --are marketed so aggressively, we’ve 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 CocaCola or Pepsi fans: Find your brand in a blind tasting.
     We invited staff volunteers who had a strong liking for either CocaCola Classic or Pepsi, Diet Coke, or Diet Pepsi. These 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 fed 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 participants’ choices with what mere guesswork could have accomplished.
     Getting all four samples right was a tough test, but not too though, 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 out 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 preference 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.
The underlined word" burnout" (Para. 5) here refers to the state of ______.
选项 A、being seriously burnt in the skin.
B、being unable to burn for lack of fuel
C、being badly damaged by fire
D、being unable to function because of excessive use
答案D
解析 词汇题。本题需要根据上下文推断出burnout一词的意义。burnout一词出现在文中第五段的第二句话“Overall，half the participants did about as well on the last round of tasting as on the first，so fatigue，of taste burnout，was not a factor．”中，在这句话中，taste burnout前出现了表示“或者，也就是说”的Or一词，也就是说“味觉burnout”是对fatigue(疲倦，疲劳)一词的解释。由此可以判断四选项中只有选项D为正确答案。选项A说“表皮严重烧伤”，选项B说“因为缺少燃料而不能燃烧”，选项C说“被火严重烧伤”，这三个选项都不能在意义上与文中的fatigue的意思相对等，故均不是正确答案。
