Question ID:PT41 S1 Q12 Passage:Poor nutrition is at the root of the violent behavior of many young offenders.  Researchers observed that in a certain institution for young offenders, the violent inmates among them consistently chose, from the food available, those items that were low in nutrients.  In a subsequent experiment, some of the violent inmates were placed on a diet high in nutrients.  There was a steady improvement in their behavior over the four months of the experiment.  These results confirm the link between poor nutrition and violent behavior. Stem:Which one of the following, if true, most strengthens the argument? Correct Answer Choice:EChoice A:Some of the violent inmates who took part in the experiment had committed a large number of violent crimes. Choice B:Dietary changes are easier and cheaper to implement than any other type of reform program in institutions for young offenders. Choice C:Many young offenders have reported that they had consumed a low-nutrient food sometime in the days before they committed a violent crime. Choice D:A further study investigated young offenders who chose a high-nutrient diet on their own and found that many of them were nonviolent. Choice E:The violent inmates in the institution who were not placed on a high-nutrient diet did not show an improvement in behavior.
