The human craving for sweets was once beneficial: it attracted people to foods that were healthful (ripe fruit, for example) in preference to foods that were not healthful (unripe fruit, for example). However, now that suger has been refinded, it follows that a craving for sweets is no longer beneficial, because refined sugar is not healthful
Which of the following, if true, would most strenthen the argument above?
A Some foods can be healthful when cooked even if they are not healthful when eaten new
B Some people who crave sweets are more likely to eat a piece of ripened fruit than they are to eat a piece of candy
C People who crave sweets are more likely to eat a food that contains refined sugar than a naturally sweet food like ripe fruit
D Prehistoric humans probably were not able to distinguish between healthful foods and unhealthful foods without relying on their sense of taste
E Some unrefined foodstuffs are no more nutritious than their refined counterparts
Why choose C, seems not strengthen the argument
Please help
结论是：craving for sweets is not beneficial----because refined sugar is not healthful
前提中：ripe fruit is healthy,unripe fruit is not healthful
选项C正好说crave sweets的人更会去吃不健康的refined sugar，支持结论中的not beneficial，并且比较对象是健康食物ripe fruit，算是正确的比较。B就是一个无关比较。一点想法。
