Liza is conducting an experiment to determine whether toy preference by gender is natural. She recruits seven kids in the neighborhood, from 4 to 10 years old. She places them in a room with a toy truck and a baby doll. All the boys played with the truck, and the girls with the doll, so she concludes that gendered toy preference is determined by nature. Why might her results be wrong?

A. The children’s age range is too wide for the experiment to be accurate.

B. The experiment doesn’t give the children a choice of a neutral toy, like a top.

C. The children have likely already undergone gender socialization.

D. The children’s inclinations are not representative of their sex differences.
