  People whose bodies cannot produce the substance cytochrome P450 are three times as likely to develop Parkinson's disease, a disease that affects the brain, as are people whose bodies do produce this substance. Since cytochrome P450 protects the brain from toxic chemicals, toxic chemicals probably play a role in the development of Parkinson's disease.

  Which of the following, if true, most strongly supports the argument?

  A:It will soon be possible for cytochrome P450 to be synthesized for the treatment of people whose bodies cannot produce this substance.

  B:Many people whose bodies are unable to produce cytochrome P450 lack the ability to produce certain other substances as well.

  C:Cytochrome P450 has no effect on the brain other than to protect it from toxic chemicals.

  D:People with Parkinson's disease often exhibit a marked lessening in the severity of their symptoms when they are treated with dopamine, a chemical produced naturally in the brain.

  E:Many people with Parkinson's disease have the ability to produce cytochrome P450 naturally.

  最佳解析:本题为GRE标准支持题“支持在支持结论”,结论为“toxic chemicals probably play a role in the development of Parkinson's disease”关键词为主语“toxic chemical”,涉及这一概念的选项只要有(C)选项,说明P450的仅有作用是保护大脑不受有毒化学物质的伤害,最好的支持了上面的结论,所以(C)is correct。

  答案:C
