Reading Comprehension

I have been practising RCs from Veritas Prep RC guide that I find very good. I will write pros and cons in a separate thread later, but ,for the moment, I have few doubts.

As it is difficult to type whole RC, i will write question#.

Q80 -> Which of the following does the author NOT mention as being an advantage of neuroimaging?

The incorrecte AC D has explanation as follows :
Since Neuroimaging is "non-invasive", humans (and perhaps, animals) that have not sustained injuriesn can be studied.

My argument: I consider this as not mentioned in the passage because author does not talk about animals anywhere . On what basis, we can infer /extend the above to animals ?

Waiting for Brian or David's take on this. I took time to write this because based on this practice, one develops a method/way of thinking to each question type.
