Question ID:PT83 S3 Q5 Passage:Eating turmeric, a spice commonly found in curries, probably helps prevent Alzheimer's disease. More turmeric is consumed per capita in India than in the rest of the world, and the incidence of Alzheimer's disease is much lower there than it is worldwide. Furthermore, Alzheimer's disease is characterized by the buildup of amyloid protein plaques in the brain, and studies on animals found that curcumin‚ a compound found in turmeric‚ reduces the accumulation of amyloid proteins. Stem:Which one of the following, if true, most strengthens the argument? Correct Answer Choice:EChoice A:Rosemary and ginger, which contain compounds that affect amyloid protein accumulation much like curcumin does, are commonly found in the diets of people living in India. Choice B:Many scientists believe that the buildup of amyloid protein plaques in the brain is a symptom of Alzheimer's disease rather than a cause. Choice C:The proportion of people living in India who fall within the age group that is most prone to developing Alzheimer's disease is smaller than the proportion of people worldwide who fall within that age group. Choice D:None of the other compounds found in turmeric have been studied to see whether they affect the accumulation of amyloid proteins. Choice E:The parts of India that have the highest per capita rates of curry consumption have the lowest incidence of Alzheimer's disease.
