9. Brain scans of people exposed to certain neurotoxins reveal brain damage identical to that found in people suffering from Parkinson's disease. This fact shows not only that these neurotoxins cause this type of brain damage, but also that the brain damage itself causes Parkinson's disease. Thus brain scans can be used to determine who is likely to develop Parkinson's disease.
The argument contains which one of the following reasoning errors?
(A) It fails to establish that other methods that can be used to diagnose Parkinson's disease are less accurate than brain scans.
(B) It overestimates the importance of early diagnosis in determining appropriate treatments for people suffering from Parkinson's disease.
(C) It mistakes a correlation between the type of brain damage described and Parkinson's disease for a causal relation between the two.
(D) It assumes that people would want to know as early as possible whether they were likely to develop Parkinson's disease.
{E} It neglects to specify how the information provided by brain scans could be used either in treating Parkinson's disease or in monitoring the progression of the disease.
Answer: B but I think the answer is C
10. Almost all of the books published in the past 150 years were printed on acidic paper. Unfortunately, every kind of acidic paper gradually destroys itself due to its very acidity. This process of deterioration can be slowed if the books are stored in a cool, dry environment. Techniques, which are now being developed, to deacidify books will probably be applied only to books with historical significance.
If all of the statements in the passage above are true, which one of the following must also be true!
(A) If a book was published in the past 50 years and is historically insignificant, it will probably deteriorate completely.
(B) Almost all of the books published in the past 150 years will gradually destroy themselves.
(C) Almost all of the books that gradually deteriorate are made of acidic paper.
(D) If a book is of historical significance and was printed before 150 years ago, it will be deacidified.
(E) Books published on acidic paper in 1900 should now all be at about the same state of deterioration.
答案是: A but I think B is ok as well
因为原文:
his process of deterioration can be slowed if the books are stored in a cool, dry environment.
说明了毁坏过程可以被减慢，言下之意毁坏过程还是在继续的，只是变慢了。。
所以和 (B) Almost all of the books published in the past 150 years will gradually destroy themselves吻合。
谢谢指教!
