Question ID:PT87 S2 Q11 Passage:Unlike other mechanical devices, the clock did not evolve from the simple to the complex. The earliest clocks were also the most complicated. This is because early clocks were used primarily to predict astronomical phenomena, though the mechanisms they used for this purpose incidentally enabled one to keep track of time. Gradually the timekeeping functions became more important and the astronomical ones diminished. Stem:Which one of the following is most strongly supported by the information above? Correct Answer Choice:DChoice A:Present-day clocks are of no use in the prediction of astronomical phenomena. Choice B:The mechanisms used to predict astronomical phenomena in at least some clocks were more complicated than most more recent mechanisms used for this function. Choice C:Clocks used only for keeping time do not differ appreciably in their mechanical complexity. Choice D:The mechanisms that the earliest clocks used to predict astronomical phenomena were more complicated than the mechanisms used for timekeeping functions in some more recent clocks. Choice E:Interest in predicting astronomical phenomena has declined steadily since the invention of the first mechanical clocks.
