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?
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.
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.
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.
Researchers have not yet determined whether the metabolic rates of formerly very overweight individuals can be accelerated by means of chemical agents.
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.
正确答案写这么绕口真的就是盼你错 编题目的人应该不再活着了吧
正题：
新陈代谢低的胖子们一般通过节食减肥，减肥后新陈代谢率还是没变。
胖子们瘦下来后跟同样瘦的人相比，消耗的卡路里少蛮多。
瘦下来的胖子呢，就会胖回去，胖到体型和新陈代谢率相符合为止。
所以文章问的是： 基于什么假设题目可以下这个胖子在没有改变的新陈代谢率情况下就一定会胖回去的结论？？
看完题目脑海里应该是简单建立逻辑： 敢这么说肯定是知道胖子消耗更少的卡路里的同时，绝逼没做别的事情让他们体型保持瘦着。
再来看答案：
A
简单分析：整个句子主语Relatively few ［very overweight people］ who have dieted down to a new weight
谓语 tend to continue to consume
宾语 substantially fe
