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.
(B) Most of those at risk of heart disease may be able to reduce their risk by adopting a low-cholesterol diet.
(C) The bodies of those who have the Apo-A-IV-2 gene excrete cholesterol when blood cholesterol reaches a 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.
(E) The presence of the Apo-A-IV-2 gene may inhibit the elevation of blood cholesterol.
答案是E，那么C为什么就不对呢。这题也太变态了吧。

首先，題目選最佳，
原文的實驗結果：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.
C選項.只說明會排泄，但也不知道是否排泄量等於上升量，才使其不上升，存在不確定性
相較於E選項.用保留語氣說明可能的情況，較佳

解释的有道理。但也说明了这个题变态，在实战那种紧张状态下，如果出这么道题的话，谁还有心情揣摩措辞呢
