Suggested Answers and Explanations
1. vi
2. ii
3. vii 本段介绍了torcetrapib和statin的治病原理，但是同时短语“in contrast”与之前第二段后半段的内容呼应，暗示了这两种药在理论上能相辅相成，是理想的搭配。第一个选项无法涵盖整段意义，故选择i是错误的。
4. iii 本段分析了可能导致torcetrapibl临床试验失败的原因，后半段指出如果以上推测正确，那么未来的药物可借鉴这个试验，设法避免torcetrapib的缺陷，研制出有效的药物。viii选项无法涵盖后半段的意思。

7. A 见第二段。题目中administer一词意为“用药”，subject一词为“实验对象”之意。
8. B 见第四段“… to raise levels of HDLs, which ferry cholesterol out of artery-clogging plaques to the liver for removal from the body.”即HDLs的作用最终是将choleserol清除出人体：“… for removal from the body”。
9. B 见第四段“But HDLs are complex and not entirely understood.”
