How is virtual reality surgery performed？
A．It is performed by a computer-designed high precision device.
B．Surgeons wear virtual reality helmets to receive feedback provided by a computer.
C．Surgeons move robotic instruments by means of a computer linked to them;
D．A 3-D image records the movements of the surgeons during the operation.
参考答案
正确答案：C
解析：由第四段提到的they move instruments that are connected to a computer, which passes their movements to robotic instruments that perform. the surgery可知，医生实际是通过计算机来操纵与计算机另一端相连的自动器械，C 与此相符，故为答案。A 与原文不符，故排除；戴虚拟现实头盔是为了观察伤口，而不是接收反馈回来的信息，故B 不是答案；3-D图像的功能是为医生提供更清晰的手术区域的图像；而不是记录手术过程，因此D 不是答案。
