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.B

(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.

我怎么觉得题目压根就没有提到treatment的问题哦?

向大家求教了~~

This question stem ask you to find the logical flaw of the argument. If you can identify the logical flaw in this argument, it will be a lot easier to find the right answer.

The logical flaw is that even though brain damage caused by neurotoxins and brain damage caused by Parkinson’s disease is the same and happen together, it doesn’t mean that they have causal relationship.
