126. The public is well aware that high blood cholesterol levels raise the risk of stroke caused by blood clots, but a recent report concludes that people with low blood cholesterol levels are at increased risk of the other lethal type of stroke---cerebral hemorrhage, caused when a brain artery busts. The report suggests that because blood cholesterol plays a vita role in maintaining cell membranes, low blood cholesterol weakens artery walls, making them prone to rupture. The conclusion thus supports a long-standing contention by Japanese researchers that Western diets better protect against cerebral hemorrhage than do non-Western diets.

The argument is based on which one of the following assumption?

(A) Western diets are healthier than non-Western diets.

(B) Western diets result in higher blood cholesterol levels than do non-Western diets.

(C) High blood cholesterol levels preclude the weakening of artery walls.

(D) Cerebral hemorrhages are more dangerous than strokes caused by blood clots.

(E) People who have low blood pressure are at increased risk of cerebral hemorrhage.

这道题答案是B

我觉得也对，那D错在哪里呢？请路过的NN们解析一下，谢谢

文中没有比较CH与STROKE BY BLOOD CLOTS的严重性阿 所以D不对

文中只是说HIGH BLOOD CHOLESTEROL==>STROKE BY BLOOD CLOTS, 但是最新报道说因为种种的原因, LOW BLOOD CHOLESTEROL==>OTHER TYPE OF STROKE(CH),  结论西方食品预防CH比非西方食品好

所以由题干第二部分最新报道指出的CH与BLOOD CHOLESTEROL的关系, 不难得出ASSUMPTION应该是西方食品应该是HIGH BLOOD CHOLESTEROL的
