Sorting the evidence — a decade-long pattern

Farah, 26, has since her teenage years believed she has a 'sixth sense' that lets her know when something bad is about to happen to a family member, dresses in a distinctive, old-fashioned style she says 'feels right,' has one close friend, and becomes noticeably anxious in group settings, often assuming others are silently judging her. Her speech is vague and sometimes hard to follow, but never incoherent. She has never had a period of clear hallucinations, thought disorder, or a fixed delusion, and her family says her presentation has been essentially unchanged for over a decade. She currently holds a part-time job.

For each statement, choose the reasoning role it plays.
