6.     Although this bottle is labeled “vinegar,” no fizzing occurred when some of the liquid in it was added to powder from this box labeled “baking soda.” But when an acidic liquid such as vinegar is added to baking soda the resulting mixture fizzes, so this bottle clearly has been mislabeled.

A flaw in the reasoning in the argument above is that this argument

(A) ignores the possibility that the bottle contained an acidic liquid other than vinegar

(B) fails to exclude an alternative explanation for the observed effect

(C) depends on the use of the imprecise term “fizz”

(D) does not take into account the fact that scientific principles can be definitively tested only under controlled laboratory conditions

(E) assumes that the fact of a labeling error is proof of an intention to deceive

答案是(B) WHY?

在此预先说声:"谢谢,不胜感激!"

原文的不冒泡不一定是Bottle中不是vinegar，也可能是因为 box 中的powder不是baking soda，即结论没有排除这种可能性。即B
