单选题 From a newspaper editorial:
Many people who are addicted to heroin will eventually attempt to overcome their addiction, principally for two reasons: the expense of maintaining a heroin addiction and the fear of arrest. If heroin were legalized and made available cheaply, as some people advocate, neither of these reasons would apply.
The considerations above can best serve as part of an argument that

A、 legalizing the sale of heroin would cause the price of this drug to go down.
B、 making it easier for heroin addicts to obtain treatment for their addiction would encourage many heroin addicts to attempt to overcome their addiction.
C、 legalizing the sale of heroin would increase the number of crimes committed by heroin addicts to support their addiction.
D、 making heroin available legally and cheaply would make it leas likely that heroin addicts will attempt to overcome their addiction.
E、 (E) decreasing the severity of penalties for individuals who use heroin would not increase the number of new heroin addicts.

【正确答案】 D

【答案解析】[解析] 本题问法特别，貌似新题型，实际上是近年来对完成段落即解释题型的一种变型，即以上考虑可用于以下哪一个论述，重点找一个在逻辑上与段落推理相连贯的一项，而(D)所表达的刚好与上述推理吻合，所以(D)正确；(A)、(B)、(C)、(E)都不符合连贯的目的。
