问题 According to the passage, the attempt to eradicate the AIDS virus
What do Ho’s words "Bear in mind that undetectable does not equal absent" mean?

选项 A、AIDS virus can exist in the blood without being detected.
B、AIDS virus is undetectable in the blood.
C、No ADS virus can be detected in the blood.
D、No virus found in the blood means no ADS.

答案A

解析 对这句话的理解要结合第五段整体考虑。该段开头说The drugs have knocked the AIDS virus down to undetectable levels in the blood...最后引用专家的话undetectable does not equal absent,联系起来看只有A项符合这句话在文章中的意思。
