单选题 Which of the following would be appropriate to describe the instruments for surgical operations up until 1960s?

A、 Traditional.
B、 Simple.
C、 Remarkable.
D、 Basic.

【正确答案】 A

【答案解析】[精解] 信息来自于：And that was where we stuck．．．for many years．[B]之所以不选的原因是文章只是围绕着传统和新式而不是简单与复杂来讨论手术器械；[C]可以用指激光手术，传统的器械正好相反，问题问的是二十世纪六十年代以前的手术器械：until 1960s。
