Quizplus · Accepted Answer

Research studies have consistently found a small but significant correlation between being breastfed as an infant and later scoring higher on mental ability tests.

Thus, choice C - smarter mothers are more likely both to breast-feed and also to have smarter children - best summarizes the current knowledge of the differences in average mental ability test scores between persons who were breastfed as infants and persons who were not.
