Bernand: For which language, and thus which frequency distribution of letters and letter sequences, was the standard typewriter keyboard designed? Cora: To ask this question, you must be making a mistaken assumption: that typing speed was to be maximized. The real danger with early typewriters was that operators would hit successive keys too quickly, thereby crashing typebars into each other, bending connecting wires and so on. So the idea was to slow the operator down by making the most common letter sequences awkward to type. Bernand: This is surely not right! These technological limitations have long since vanished, yet the keyboard is still as it was then. Which one of the following, if true, could be used by Cora to counter Bernard’s rejection of her explanation? (A) Typewriters and word-processing equipment are typically sold to people who have learned to use the standard keyboard and who, therefore, demand it in equipment they buy. (B) Typewriters have been superseded in most offices by word-processing equipment, which has inherited the standard keyboard from typewriters. (C) The standard keyboard allows skilled operators to achiever considerable typing speeds, thought it makes acquiring such skills relatively difficult. (D) A person who has learned one keyboard layout can readily learn to use a second one in place of the first, but only with difficulty learn to use a second one alongside the first. (E) It is now possible to construct typewriter and word-processing equipment in which a single keyboard can accommodate two or even more different keyboard layouts, each accessible to the operator at will. _________________
I think it's A. The fact that people demanded the keyboard format they already know despite its inefficiency keeps the standard format in place even there have been technological innovations to render the standard obsolete.
Need to find Cora's rebuttal to B, who is asking why we are still using standard typewriter. There must be an adv that Cora states in C. B himself acknowledges that speed was an issue and probably a requisitie now. D's answer in to me connects that pieces well.
