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. Which one of the following is most strongly supported by the historian's statements?
A: If the keyboard had been designed for computers, then it would not have been designed to limit typing speed.
B: 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.
C: 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.
D: Early QWERTY typewriters were less likely to jam than were at least some more recent typewriters if adjacent keys were struck in quick succession.
Choose A, B, C or D as your solution.
