Explanation:

Let's review the definition of these words:

1) Concur: To have the same opinion or to agree/ for something to happen at the same time.

This word doesn't seem to fit our definition we are looking for, so let's move on.

2) Evident: Something that is plain or obvious, clearly seen and understood.

This word could fit some of the definition, but does not fit all of it.

3) Procedure: An official or established way of completing something, or a series of actions carried out in a specific order/manner.

This word does not fit any of our definition we're looking for.

4) Astute: Displaying or having the ability to correctly asses and analyze situations.

This word, based on definition, seems to best fit the one we're looking for.

So, I believe the correct answer is 4) Astute.

I hope this helps :)
