Researchers have found that when very overweight people, who tend to have relatively low metabolic rates, lose weight primarily through dieting, their metabolisms generally remain unchanged.  They will thus burn significantly fewer calories at the new weight than do people whose weight is normally at that level.  Such newly thin persons will, therefore, ultimately regain weight until their body size again matches their metabolic rate.
The conclusion of the argument above depends on which of the following assumptions?
选项为A，但A说的不就是原文中的第二句话，我以为是重复原文，就直接排除正确选项了。这道题应该怎样分析？

Which of the following, if true, most seriously calls Scott's hypothesis into question?
