### HideShow timer Statistics

Brain scans of people exposed to certain neurotoxins reveal brain damage identical to that found in people suffering from Parkinsonâ€™s disease. This fact shows not only that these neurotoxins cause this type of brain damage, but also that the brain damage itself causes Parkinsonâ€™s disease. Thus brain scans can be used to determine who is likely to develop Parkinsonâ€™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 Parkinsonâ€™s disease are less accurate than brain scans.
(B) It overestimates the importance of early diagnosis in determining appropriate treatments for people suffering from Parkinsonâ€™s disease.
(C) It mistakes a correlation between the type of brain damage described and Parkinsonâ€™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 Parkinsonâ€™s disease.
(E) It neglects to specify how the information provided by brain scans could be used either in treating Parkinsonâ€™s disease or in monitoring the progression of the disease.

Seems "correlation and causality" is an area that is tested often..

I too go with C

The passage assumes that brain damages are the sole cause of parkinson's disease..
