C. It was designed without the active involvement of skilled machinists是正确答案。文章中指出:NC技术不同于RP技术,它的程序由工程师在其计算机上编写,而不是由熟练的机修工录制自己的动作来教会机器复制这些动作。因此,NC技术设计是没有熟练的机修工的积极参与的。

unlike N/C, its programs were produced not by engineers at their computers, (but by skilled machinists), who recorded their own movements to "teach" machines to duplicate those movements.
那么n/c就是(without the active involvement of skilled machinists)。定位准,理解对长难句,选选项,要快,只根据定位去选
