题目解析:
A选项用first waterpower devices定位到原文第二句: No one knows exactly when the waterwheel was invented...这句话说了no one knows,正确,不选。B选项中的when和最后一句话的地点呼应: The device appears to have evolved no later than the fifth century B.C., perhaps independently in different regions of the Middle and Far East. B正确,不选。C的earlist定为到第一句话: Moving water was one of the earliest energy sourcesMoving water was one of the earliest energy sources.说明这个事实是肯定的。C是要选的答案D选项用arose independently对应这段的最后一句:...perhaps independently in different regions of the Middle and Far East.其中perhaps说明这个事情并不肯定。所以D不选。
