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 haemorrhage, 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 haemorrhage than do non-Western diets.
The argument is based on which one of the following assumption?OPTIONS
[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 haemorrhages are more dangerous than strokes caused by blood clots.
[E]. People who have low blood pressure are at increased risk of cerebral haemorrhage.
