只是不懂b的cognitive skill什么意思，整句话是什么意思啊？

Consumer advocate: The toy-labeling law should require manufacturers to provide explicit safety labels on toys to indicate what hazards the toys pose. The only labels currently required by law are labels indicating the age range for which a toy is intended. For instance, a "three and up" label is required on toys that pose a choking hazard for children under three years of age. Although the current toy-labeling law has indeed reduced the incidence of injuries to children from toys, parents could prevent such injuries almost entirely if toy labels provided explicit safety information.

10. Which one of the following, if true, most strengthens the consumer advocate's argument:

(A) Certain types of toys have never been associated with injury to children.

(B) Most parents believe that the current labels are recommendations regarding level of 【cognitive skill. 】

(C) The majority of children injured by toys are under three years of age.

(D) Many parents do not pay attention to manufacturers' labels when they select toys for their children.

(E) Choking is the most serious hazard presented to children by toys.

我的理解，仅供参考。

文中说玩具标签法要求玩具生产商贴处标签来显示玩具可能带来的危害。现在实际上玩具商只在玩具上贴上个年龄标记，比如说某个玩具供三岁及三岁以上的孩子使用， 这实际上显示了可能给三岁以下的小孩带来的卡在喉咙窒息的危险。虽然这样的标签的确降低了危险发生的可能性，但是父母们还是能预防这样的危险的。原因是(如B所说)，父母们把这个“三岁及以上”这个标签看成是孩子认知能力的划分，即父母们认为三岁及以上的孩子的认知能力可以让他玩这个玩具了。而不是从危险角度来看这个标签的。

Agree with dansy.

cognitive skill -- 认知能力．

If B is true -- right now most parents believe the labels are regarding cognitive skill levels, not related to hazards, then the author's recommendation of explicit safety label would be effective to warn parents about the potential danger.  Therefore, B strengthens the argument.

the passage is arguing against a popular label strategy, which gives the age range for which a toy is intended, in the toy industry.the author asks for more information rather than the age range to help parents to prevent the risk associated with the toy.

b says that parents misunderstand  what the age range suggests,so if what the author asks for in the passage is fulfilled , this will not happen.
