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?

(A) Relatively few very overweight people who have dieted down to a new weight tend to continue to consume substantially fewer calories than do people whose normal weight is at that level.

(B) The metabolisms of people who are usually not overweight are much more able to vary than the metabolisms of people who have been very overweight.

(C) The amount of calories that a person usually burns in a day is determined more by the amount that is consumed that day than by the current weight of the individual.

(D) Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.

(E) Because of the constancy of their metabolic rates, people who are at their usual weight normally have as much difficulty gaining weight as they do losing it.
这题 答案A 我怎么觉得和原文说的刚好是反的 呢     ？？

Use negation.

If most very overweight people can continue to consume less food than do normal people, they won't gain weight. However, the conclusion says they will.

题目：庞然的metabolic rate 低。胖人减肥之后，他们的metabolism rate 不变。 他们比普通人燃烧的C要少。所以，胖人减肥后会增重，直到match他们的metabolic rate。
假设
很少胖人减肥之后消耗比正常人多的C

弱弱的问一句，是我们把consume calory 理解成了 burn  calory ，所以错了么

consume  calory  究竟什么意思？

自问自答
原来是吃的意思

comsume有吃完的意思~就是减肥了，吃的还那么多，结论是又会胖起来，所以隐含的假设就是在rate没变时，饮食量也没变~
