In an effort to curb drug abuse, the government has imposed strict laws to prosecute the dealers. However, such an initiative is unlikely to be effective. Prosecuting dealers will lead to a shortage of drugs. At the same time, because no efforts are being taken to curb demand, drugs will be sold at a premium, attracting more people to the very remunerative job of drug dealing. Therefore, to effectively reduce drug abuse, the government will have to prosecute the drug users and not dealers.
Which of the following is the most relevant information in evaluating the credibility of the argument?
A. Whether efforts have been successfully taken in any other country to regulate drug users.
B. Whether the payoff from selling drugs outweighs the severity of the punishment
C. Whether drugs will continue to be sold at a premium when there are dealers in the market again
D. Whether the majority of the users will be willing to pay a premium to continue to use the drugs
The author assumes that the demand will continue to be at the same level and concludes that drugs will be sold at a premium. However, If there are no buyers at the premium rate then rates will have to go back down and dealing will not be as lucrative. Conversely, if there are buyers, the rates will go up just like the author predicts. This option offers two paths and therefore is useful in evaluating the argument
E. Whether the government will be able to keep track of new dealers as and when they enter the market
IMO D
