Among the many advantages of breastfeeding, the decreased likelihood of childhood obesity is often cited. In fact, the CDC continues to make available summary data from numerous U.S. studies that show correlations between healthy childhood weights and breastfeeding as well as studies that suggest that the longer time a child was breastfed, the more decreased is the likelihood of obesity. Nevertheless, results of more recent studies, including one conducted in Belarus, suggest that breastfeeding has little or no effect on childhood weights.
Which of the following can be most logically inferred from the information in the passage?
(A) More recent studies have greater scientific veracity as they reflect more up-to-date methods and information.
(B) While a correlation may exist between breastfeeding and healthy childhood weights, a cause-and-effect relationship may not exist.
(C) The CDC cannot give credence to a childhood obesity study conducted outside the U.S.
(D) Factors accounted for in the studies conducted in the U.S. were not accounted for in studies conducted in Belarus.
(E) The CDC does not update all of its website information with consistent regularity.
