Question ID:PT59 S3 Q21 Passage:Historian: The standard "QWERTY" configuration of the keys on typewriters and computer keyboards was originally designed to be awkward and limit typing speed. This was because early typewriters would jam frequently if adjacent keys were struck in quick succession. Experiments have shown that keyboard configurations more efficient than QWERTY can double typing speed while tremendously reducing typing effort. However, the expense and inconvenience of switching to a new keyboard configuration prevent any configuration other than QWERTY from attaining widespread use.  Stem:Which one of the following is most strongly supported by the historian's statements? Correct Answer Choice:EChoice A:Most people who have tried typing with non-QWERTY keyboards have typed significantly more quickly using those keyboards than they usually have done using QWERTY keyboards. Choice B:Early QWERTY typewriters were less likely to jam than were at least some more recent typewriters if adjacent keys were struck in quick succession. Choice C:If the designers of early typewriters had foreseen the possibility that technology would make it possible for adjacent keyboard keys to be struck in rapid succession without jamming, then they would not have proposed the QWERTY configuration. Choice D:The benefit to society that would result from switching to a keyboard configuration other than QWERTY is significantly greater than the overall cost of such a switch. Choice E:If the keyboard had been designed for computers, then it would not have been designed to limit typing speed.
