问题 Operation research is a scientific method of providing executive department with a quantitative basis for decisions______ the operations under their control.
选项 A、regarding
B、as to
C、on
D、considering
答案 A
解析 regarding“关于”。as to“关于；至于"，用在此处不合适；decision on“对……做出的决定”，不合句意；considering“考虑到；鉴于”。题句意为：“运筹学是一种科学方法，它为执行部门对其掌管下的各种活动作决定时提供数量根据。”
