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.
