　　8.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.

　　If the statements above are true， which of the following must， on the basis of them， also be true?

　　(A)The earliest stars contained only hydrogen.

　　(B)Some stars were formed bore the universe was two billion years old.

　　(C)The carbon in the gas cloud later formed pArt of some stars.

　　10.Sleep deprivation is a known cause of workplace error， and many Physicians frequently go without sleep for periods of 24 hours or more. However， few of these Physicians have， in the course of a routine examination by a peer， been diagnosed with sleep deprivation.So there is little cause for concern that habitual sleep deprivation will cause widespread Physician error.

　　The answer to which of the following questions would be most helpful in evaluating the argument?

　　(A)Do Physicians who have been diagnosed with sleep disorders also show signs of other ills not related to sleep deprivation?

　　(B)Is the ability to recognize the symptoms of sleep deprivation in others significantly impaired by habitual sleep deprivation?

　　(C)Do fActors other than habitual sleep deprivation ever lead to errors in the workplace on the pArt of Physicians?

　　deprivation?

　　11.A list of the fifteen operas most frequently performed in recent times includes no works by the nineteenth-century German composer Richard Wagner. Although Music producers tend to produce what audiences want，relative infrequency of performance probably does not indicate lack of popularity in Wagner's case， since Wagner's operas are notoriously expensive to perform on stage.

　　The statements above， if true， most strongly support which of the following?

　　(A)The body of the dwarf woolly mammoth was less than three-fourths the size of the body of an average adult nondwarf woolly mammoth.

　　(B)None of the teeth of the dwarf woolly mammoth that were recently discovered was as large as any of the teeth of nondwarf woolly mammoths that have been discovered.
