问题 According to Richard Satava, the application of virtual reality to medicine______.
How is virtual reality surgery performed?

选项 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.

答案C

解析 第四段最后两句话说"As surgeons watch a three-dimensional image of the surgery,they move instruments that are connected to a computer,which passes their movements to robotic instruments that perform the surgery".C选项几乎是原文再现,所以是正确答案。A和D属于无中生有的错误。B太片面。
