Parsons has has this free public life drawing session ever since I was in high school , and probably long before that . Back then , that building was rather obscure , with undecorated concrete entrance , rather dim lights , and an unsmiling security guard . The elevator is equally unflattering , around in a dead end corner in the back , with even dimmer lighting , and we take its quivering trip up to the 11th floor .

Question: What is the reason that the reason taking the elevator is a quivering trip ?
Answer: The elevator is poorly maintained and shakes .I have claustrophobia and closed places make me quiver .None of the above choices .The elevator causes people to shiver .
