How do people attempt to explain the behaviors of others?

When you see other people in the world, there are several predictions you often make about them.  You often want to predict what they will do (like whether someone standing at a crosswalk is about to head out into the street in front of your car).  You also want to predict why they do what they do.  For example, that person might be walking into traffic, because they are in a hurry or because they are generally impulsive.

what are the options

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.
