The average level of fat in the blood of people suffering from acute cases of disease W is lower than the average level for the population as a whole. Nevertheless, most doctors believe that reducing blood-fat levels is an effective way of preventing acute W.
Which one of the following, if true, does most to justify this apparently paradoxical belief?
(A) The blood level of fat for patients who have been cured of W is on average the same as that for the population at large.
(B) Several of the symptoms characteristic of acute W have been produced in laboratory animals fed large doses of a synthetic fat substitute, though acute W itself has not been produced in this way.
(C) The progression from latent to acute W can occur only when the agent that causes acute W absorbs large quantities of fat from the patient’s blood.
(D) The levels of fat in the blood of patients who have disease W respond abnormally slowly to changes in dietary intake of fat.（C）
(E) High levels of fat in the blood are indicative of several diseases that are just as serious as W.
我觉得D选项很好啊，C里那个agent莫名其妙哇~~

得W病的人血脂比普通人的低这一点C没法解释呀？

d不一定的呀，基数大后续摄入的少，不见得就会低
反过来c的话，高血脂是acute w的充分必要条件

重新看看

agent就是指病人喽

有W病的人的血脂比普通人的低，但是医生还是说保持低血脂是避免得W病的方法。
我觉得D的逻辑是：那些高血脂的人得了W后，levels of fat in the blood 就对饮食中脂肪的摄入反应很慢。不就正好解释了题干中所说的：有W病的人血脂比普通人低了。吗？
我觉得C选项只解释了为什么要保持低血脂，而没解释为什么有W病的人的血脂比普通人的低呀

难道不应该是higher么？怎么会是lower
