问题 In the design of medical experiments, the need for (i)________ assignment of treatments to patients must be (ii)________ the difficulty of persuading patients to participate in an experiment in which their treatment is decided by chance.

选项 A、independent…amended by
B、competent…emphasized by
C、mechanical…controlled by
D、swift...associated with
E、random…reconciled with

答案 E

解析 空格(ii):
- 方程等号:空格(i)体现治疗方案和说服病人的困难之间的对立关系。
- 强词和对应:空格(i)体现研究和困难的对立关系,即研究必须“克服”困难。amended by被…修改,emphasized by被…强调,controlled by被…控制。
空格(i):
- 方程等号:in which引导的定语从句修饰experiment,前后句意同义重复。
- 强词和对应:an experiment和assignment of treatments同义重复,后文说决定治疗方案是随机的(by chance),因此空格(ii)和by chance取同,体现治疗方案的分配是“随机的”independent独立的(对),competent有能力的(错),mechanical机械的(错),swift迅速的(错),random随机的(对),综合空格(i),答案选E。
