　　The public is well aware that high blood cholesterol levelsraise the risk of stroke caused by blood clots, but a recent report concludesthat people with low blood cholesterol levels are at increased risk of theother lethal type of stroke---cerebral hemorrhage, caused when a brain arterybusts. The report suggests that because blood cholesterol plays a vita role inmaintaining cell membranes, low blood cholesterol weakens artery walls, makingthem prone to rupture. The conclusion thus supports a long-standing contentionby Japanese researchers that Western diets better protect against cerebralhemorrhage than do non-Western diets.

　　The argument is based on which one of the followingassumption?

　　A. Western diets arehealthier than non-Western diets.

　　B. Western dietsresult in higher blood cholesterol levels than do non-Western diets.

　　C. High bloodcholesterol levels preclude the weakening of artery walls.

　　D. Cerebralhemorrhages are more dangerous than strokes caused by blood clots.

　　E. People who havelow blood pressure are at increased risk of cerebral hemorrhage.
