Question

which statement describes the u.s organ donation system?
a. about 200 lives are saved per year.
b. it is mandatory.
c. transplant recipients must pay for organs.
d. the waiting lists for organs are very long.

Explanation:

The U.S. organ donation system relies on voluntary donation, not mandatory (eliminating B). Organs are not sold; recipients pay for transplant procedures but not organs (eliminating C). Thousands of lives are saved yearly, far more than 200 (eliminating A). A persistent issue is the severe shortage of organs, leading to very long waiting lists.

Answer:

D. The waiting lists for organs are very long.
