Explanation:

• Question 89: Elisabeth Kubler - Ross' stages of death are denial, anger, bargaining, depression, and acceptance. Bargaining is one of them.
• Question 90: Cryosurgery uses extreme cold to destroy abnormal tissue. Verrucae (warts) can be treated with cryosurgery.
• Question 91: An angiogram involves injection of a contrast medium, PET and CAT scans involve radiation - related procedures with some level of invasiveness in terms of tracer injection. Gamma - Knife Surgery is a form of invasive neurosurgery. Roentgenography is X - ray imaging, and among the options, none are truly non - invasive roentgenography techniques in the strictest sense, but compared to the others, the closest conceptually is related to X - ray angiogram which can be considered a form of roentgenography and is less invasive than the others in some contexts.
