In the next four years, the number of doctors, nurses, and other healthcare workers will increase significantly worldwide. Even so, the average compensation received by such professional will not decline but rather is likely to increase. This is due, at least partly, to the fact that the median age of the world’s population will increase steadily in this same period of time.

The argument above depends logically upon which of the following assumptions?

a. The increase in the number of health care workers will be responsible for the increase in the average life span
b. The compensation of doctors and physical therapists who treat the elderly will incrase more than that of other health care workers
c. As a group, older people receive more attention from health care workers than do younger people.
d. Geriatrics, a branch of medicine focusing on the health problems of older people, is the most expensive element of American health care.
e. Increase in the median age of the population will occur in all regions of the world.

as i understand, this CR is that the numbers of doctors and nurses increases >>>health care increases>>>>people getting health care are increase>>>>>>> MEDIAN AGE increass in all over the world... means people will live longer because of increasing of health care
SO i chose A as the answer but its not the right answer and i dunno why.. anybody can please explain?
explain please. dont just give the answer yo chose

选C吧，因为老年人需要的帮助多所以导致医生需求量的增加并不能稀compensation的减少
