The number of hospital emergency room visits by heroin users grew more than 25 percent during the 1980s. Clearly, then, the use of heroin rose in that decade.
The author’s conclusion is properly drawn if which one of the following is assumed?
(A) Those who seek medical care because of heroin use usually do so in the later stages of addiction.
(B) Many heroin users visit hospital emergency rooms repeatedly.
(C) The number of visits to hospital emergency rooms by heroin users is proportional to the incidence of heroin usage.
(D) The methods of using heroin have changed since 1980, and the new methods are less hazardous.
(E) Users of heroin identify themselves as such when they come to hospital emergency rooms.

Is the OA C?
If number of visits to hospital emergency rooms is NOT propotional to the incidences of heroin usage, the argument breaks. This is because the argument assumes that 25% more vists to emergency rooms was propotional to rise in usage of heroin

The increase in visits are the main determinant factor for assuming that the usage has increased. But what if the increase in visits was due to the same number of patients only. So, (C) is our assumption.
