问题 In large doses, analgesics that work in the brain as antagonists to certain chemicals have caused psychological disturbances in patients, which may limit their potential to relieve severe pain.

选项 A、which may limit their potential to relieve
B、which may limit their potential for relieving
C、which may limit such analgesics’ potential to relieve
D、an effect that may limit their potential to relieve
E、an effect that may limit potential of such analgesics for relieving

答案 D

解析 A、B、C都错在which从句与其先行词psychological disturbances被其他成分分隔,使用which会导致此非限定性从句的修饰对象不清,从而产生歧义;D中用an effect清楚指代psychological disturbances,that从句对此效应进行了补充解释。
