A. to learn from their mistakes, the neuroscientists of Albuquerque in New Mexico scanned the brains of 96 convicts.
B. to learn from their mistakes, the brains of 96 convicts were scanned by neuroscientists in Albuquerque of New Mexico.
C. of learning to avoid mistakes, the brains of 96 convicts were scanned by neuroscientists in Albuquerque, New Mexico.
D. of learning to avoid their mistakes, neuroscientists in Albuquerque of New Mexico, scanned the brains of 96 convicts.
E. of learning from their mistakes, neuroscientists in Albuquerque, New Mexico, scanned the brains of 96 convicts.

A and B: some people are incapable to learn
The portion in red is unidiomatic.
Incorrect: X is incapable to do Y
Correct: X is incapable OF doing Y
Eliminate A and B.

C: To understand...the brains of 96 convicts
Here, to understand seems to refer to the brains, implying that THE BRAINS are attempting TO UNDERSTAND -- a nonsensical meaning.
Eliminate C.

If the original sentence conveys a logical meaning, the correct answer should retain this meaning.
A: from their mistakes = as a RESULT of their mistakes
D: to avoid their mistakes = to not MAKE mistakes
Since D does not retain the meaning of the original sentence -- a meaning that is logical -- eliminate D.

The correct answer is E.

Option A: Wrong
Here, clearly, no difference in the response to the question asked. A clear case of repetition and plagiarism of statement which in actual fact does not solve nothing herein.

Option B: Wrong
The use of the preposition ''To'' is a supposition herein, it doesn't really buttress the objective of doing the particular thing or action so mentioned here.

Option C: Wrong
No logical punctuation here especially between the emphatic stresses from the underlined statement. Too lumped up with little space for comprehension.

Option D: Wrong
This would have been correct in all terms so used but it does have too much complexity surrounding it especially the line where it said ''learning to avoid their mistakes''. This line could have been better put together.

Option E: Right
Here, punctuation of the lines in the statement and the emphatic stresses on the statement gave it the best meaning among others. Well punctuated with the commas (,). The most correct of all.
