In am experiment, two-year-old boys and their fathers made pie dough together using rolling pins and other utensils. each father-son pair used a rolling pin that was distinctively different from those used by the other father-son pairs, and each father repeated the phrase"rolling pin" each time his son used it. but when the children were asked to identify all of the rolling pins among a group of kitchen utensils that included several rolling pins, each child picked only the one that he had used.
Which one of the following inferences is most supported by the information above?
(A)The children did not grasp the function of rolling pin.
(B)no two children understood the name"rolling pin"to apply to the same object
(C)the children understood that all rolling pins have the same general shape
(D)each child was able to identify correctly only the utensils that he had used.
(E)the children were not able to distinguish the rolling pins they used from other rolling pins.
B. Why D is wrong?作者: atongmu 时间: 2003-3-20 09:49
D 错在only。文中的实验只能推出孩子可以认出用过的东西，无法推出孩子无法认出所有没用过的东西。
在逻辑题中，切忌推而广之。再次强调一点，选项中有极端性意思要千万当心。
