Question ID:PT51 S1 Q8 Passage:We can now dismiss the widely held suspicion that sugar consumption often exacerbates hyperactivity in children with attention deficit disorder. A scientific study of the effects of three common sugars‚ sucrose, fructose, and glucose‚ on children who have attention deficit disorder, with experimental groups each receiving a type of sugar in their diets and a control group receiving a sugar substitute instead of sugar, showed no statistically significant difference between the groups in thinking or behavior. Stem:Which one of the following, if true, would most weaken the argument above? Correct Answer Choice:CChoice A:Only one of the three types of sugar used in the study was ever widely suspected of exacerbating hyperactivity. Choice B:The consumption of sugar actually has a calming effect on some children. Choice C:The consumption of some sugar substitutes exacerbates the symptoms of hyperactivity. Choice D:The study included some observations of each group in contexts that generally tend to make children excited and active. Choice E:Some children believe that they can tell the difference between the taste of sugar and that of sugar substitutes.
