Answer to Question 1

ANS: B
Osteoarthritis is characteristic of degeneration that results from joint usage. This disease is a good example of the wear-and-tear theory; repeatedly injuring one organ or body system, such as oc-curs during playing sports, may result in premature aging and diseases such as osteoarthritis. The free radical theory states that cell damage is a result of the accumulation of oxygen radicals. The gene theory states that genes govern cellular mortality. The cross-link theory is related to the ac-cumulation of cross-linked proteins, which may cause disease.

Answer to Question 2

ANS: A
The activity theory states that successful aging equals active aging, which is related to the per-son's need to maintain a productive life for it to be a happy life. Curtailing increases in physical activity is diametrically opposite to continuing a daily walking routine and contrary to the tenets of the activity theory. End-of-life decisions and avoiding exposure to crowds are not related to the activity theory since they do not directly affect the productiveness of a client's life.
