Healthcare costs will rise in the future because
a. a large group of people will become senior citizens
b. healthcare providers will charge more for certain types of patients
c. all medicine will become generic and easily accessible
d. doctors will refuse to see patients who can't pay in cash

Answer A) is correct. Due to the growing aging population in this country, more and more elderly citizens will put an increasing strain on the cost of healthcare. Whilst people living longer is a credit to improvements in medicine, older people are likely to have far poorer health and require a greater number of appointments and procedures.
