2. 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.
