8.People whose bodies cannot produce the substance cytochrome P450 are three times as likely to develop Parkinsons 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 Parkinsons disease.
Which of the following, if true, most strongly supports the argument?
It will soon be possible for cytochrome P450 to be synthesized for the treatment of people whose bodies cannot produce this substance.
Many people whose bodies are unable to produce cytochrome P450 lack the ability to produce certain other substances as well.
Cytochrome P450 has no effect on the brain other than to protect it from toxic chemicals.
