问题 A spear or a robot has the quality of technology only when it ______.
The examples of the Challenger and Chernobyl cited by the author serve to show that______.
选项 A、if not given close examination, technology could be used to destroy our world
B、technology is a human creation, so we are responsible for it
C、technology usually goes wrong, if not controlled by man
D、being a human creation, technology is liable to error
答案B
解析 本题问：作者引用挑战者号和Chernobyl号的例子是用来说明什么?B项的意思是“技术是人类的创造，因此我们必须为它负责”。文章第二段在举了挑战者号和Chernobyl号的例子后提到，“Since technology is a human creation， we are responsible for what is done with it”，因此B项为正确答案。
