Which of the following, if true, most seriously weakens the argument?
A. Sulfites occur naturally in most wine.
B. The sulfites that can produce an allergic reaction are also commonly found in beverages other than wine.
C. Wines without added sulfites tend to be at least moderately expensive.
D. Apart from sulfites, there are other substances commonly present in wine that can trigger allergic reactions.
E. Wine without added sulfites sometimes becomes undrinkable even before the wine is sold to consumers. 答案是a，但我觉得d也行啊，也是他因削弱，求指教 作者: 甜蜜小乌龟 时间: 2011-7-5 22:16
恩 我觉得题目的逻辑是sulfite引起过敏 不带sulfite的wine不过敏 结论是只要没有添加sulfite的wine就可以喝
那么削弱的应该是结论 并且与论据相关 A与D相比，A跟论据更相关作者: rikihsu 时间: 2011-7-6 01:48
