According to the author, the computer is an extension of our intellects. What, then, is used as an extension of our physical power?

选项 A、Science.
B、Engines
C、Industrialists.
D、Technology.

解析本题中extension意思是“扩展，扩大”。可根据文章倒数第二句中for just the same reason that“同样道理…”，以及题干中的physical power“体力”就是指原文中的muscle，推断出正确答案为[B]。
