大家有没有发现，有时候我们是把题目做对了，但是，对于错误选项的理解却与给出的解释不一致。假设给出的解释是权威的，例如OG。那么这种差异其实在某种程度上反映了我们的思维还不是ETS要的标准答案。
我们举例，讨论讨论吧，好吗？
例1：
46. Twelve healthy volunteers with the Apo-A-IV-1 gene and twelve healthy volunteers who instead have the Apo-A-IV-2 gene each consumed a standard diet supplemented daily by a high-cholesterol food. A high level of cholesterol in the blood is associated with an increased risk of heart disease. After three weeks, the blood cholesterol levels of the subjects in the second group were unchanged, whereas the blood cholesterol levels of those with the Apo-A-IV-1 gene rose 20 percent.
Which one of the following is most strongly supported by the information above?
A. Approximately half the population carries a gene that lowers cholesterol levels. （无提及）
B. Most of those at risk of heart disease may be able to reduce their risk by adopting a low-cholesterol diet. （与原文逻辑基础“a standard diet supplemented daily by a high-cholesterol food”相反）
C. The bodies of those who have the Apo-A-IV-2 gene excrete cholesterol when blood cholesterol reaches a certain level. （不严密，原文是unchanged, 这里好像意味着change to certain level）
D. The presence of the Apo-A-IV-1 gene seems to indicate that a person has a lower risk of heart disease. （相反）
给出的答案是：
A：无关
B：无关
C：与所提供的信息相反
D：无关
大家是怎么看着几个选项的呢？ 谢谢大家的意见！
