Answer:
A. Businesslike .
Step-by-step explanation:

And in it, the narrator was seen to dissect his own brain, to find out that it is functions from the movement of air in between the gold leaves. The rate at which the air passes depends on the atmospheric pressure, thus the different computing manners of different people. He also discovers that the same air pressure below and above ground will lead to the cessation of time itself.
