问题 For centuries animals have been used as ____ for people in experiments to assess the effects of therapeutic and other agents that might later be used in humans.

选项 A、benefactors
B、companions
C、examples
D、precedents
E、surrogates

答案E

解析 - 方程等号：later表现时间对比，前后句意反义重复。
- 强词和对应：空格和use构成反义重复，之后在人身上使用，所以之前在人身上“不使用”药，在动物身上使用药物，所以动物就是人类的替代品。benefactor捐赠者，companion同伴，example例子，precedent先例，surrogate替代品。答案选E。
