参考答案
正确答案：D
[答案]D。[解析] 该题可直接借助常识判断答案D合理。也可以借助原文：利用题干中的核心短语“wiped out”作为答案线索，发现答案相关句：He has calculated that the drugs should be able to wipe out remaining viruses—at least from known reservoirs(储主)throughout the body—two to three years，But the only way to prove eradication(与wiped out是近义词)would be to stop the drugs and see if the virus comes back．该句说“证明是否彻底消灭了病毒的惟一方法就是观察停药后病毒是否会卷土重来。”因此D是答案。 wipe out v．消灭，垮台
