Tom is a loner, who has few friends and seems incapable of sympathy or empathy. He is showing signs of the __________ personality disorder.
A. antisocial
B. schizoid
C. paranoid
D. none of the above

Answer 1

The first one... B. Unusual because it's 'trivial.'
The second one... B. Excessive drinking, smoking, and arguing are self-defeating because they are harmful and self-inflicted.
The third one... A. The antisocial personality's main components are lack of sympathy or empathy, or purposely physically harming people or animal.

Answer 2

The first one if either B or Do, but i'm leaning more towards D because delusional is like psychotic behavior and to me it sounds psychotic.

The second one is D, I think or B. Whenever you have these kind of questions and there is one with words you don't understand look them up and it will be easier to decide. That's what I'm doing.

The third one is definitely A, because those are antisocial behaviors.
