Difficulty—

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.

Option A Wrong
Brain scans reveals brain damage when diagnoised automatically means the patient is close to or already suffering from Parkison's disease. It has nothing to do with other methods since one could lead to other with regards to medical examination.

Option B: Wrong
In fact, it is contrary here because the importance of such diagnosis is and should be timely enough in other to help cater for it so early too. It doesn't over-estimate the importance whatsoever contrary to the supposition of the option of the statement.

Option C: Wrong
It did not elaborate on the typology of brain damage neither did it infer that the diseases are caused by the same causal agents. it'd be however speculative to think in a manner that hasn't been proven by any medical examination.

Option D: Wrong
This is wrong from the passage statement. The aim of the patient was to test for brain damage and not parkison's disease although it'd be known to him that he/she is at the verge of been tested positive to parkison's disease because the two has identical relationship.

Option E: Right
This is so correct. As it seems, the aim of this diagnosis is to determine if there's brain damage and not majorly Parkison's disease so it should be expected that the treatment procedures would be specifically for brain damage and not for Parkison's disease. This was aptly captured by the question's specification.
