逻辑 Critical Reasoning-7238

标记
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】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.

选项是否正确?

  • 正确
  • 错误

不变的量是新代的速度,作者说这些人因为代谢慢会渐渐变回原来那样胖,如果想不让他们变那么胖,那就需要接着少吃,因为他们的代谢速度是一定的。反之变胖前题是什么呢?就是他们没有接着少吃。 而这个选项说的是什么决定calorie的燃烧量,

一天消耗的卡路里 更多地被决定 通过现在每天摄入的数量,而不是现在的体重。 取反 消耗的卡路里是由体重决定的,跟文章内容一致,嘉庆

本来就是这样的啊 assumption是题目中没说过的想要得到结论的necessary的条件 ,该选项只是在重复文中已知信息,并不是assumption

when you negate an assumption, the resulting statement should DESTROY the argument! so, this choice is precisely the opposite of what you're looking for.

无关--消耗的卡路里和 摄入热量有关的程度 大于和 体重有关的程度 --取非,如果二者反过来,并不能削弱“如此减肥会时他们复胖”即:和体重有关程度大,那低体重就消耗低calories,所以他们就不会复胖?新陈代谢和calories的差别才是导致胖的直接原因

如果 the amount of calories that a person usually burns in a day is determined by the amount that is consumed. 那么newly thin & normally thin consume the same # of calories 应该燃烧同样数量的脂肪。 题目中说:new weight burn less than normal weight 所以和argument 矛盾 2.negation: The amount of calories that a person usually burns in a day is determined more by the current weight of the individual than more by the amount that is consumed that day. new weight & normal weight consume same number of Calories new weight burn less than normal weight 然后就支持了结论

其实AC是正反面的感觉。题干是说,减肥的人因为新陈代谢还是慢,燃烧卡路里慢,所以一定会bounce back。 那有没有可能我摄入的少了,燃烧慢一点也无所谓了呢?A取非就是这个; C只是说了燃烧量是由摄入量决定的,没有说现在的摄入量是和以前一样还是变少了,所以没法全部来增强这个必然性

曲非反而加强了结论

研究发现,新陈代谢率相对低的胖子们 主要通过节食减肥,他们的新陈代谢几乎不变。因此,当他们体重下降后,会比正常那个体重的人卡路里燃烧的更慢。这些新瘦子最后的下场时,反弹回新陈代谢率所对应的体重。 -- 一个人一天燃烧的卡路里由摄入量而非当时的体重决定。变量太多,无法做推导。

卡路里的燃烧由其消耗量决定而非体重决定。原文说了,曾经胖-代谢慢-燃烧少。和原文矛盾

说卡路里的数量是由什么决定的,无关,杀
