10.   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(B) Typewriters have been superseded in most offices by word-processing equipment, which has inherited the standard keyboard from typewriters.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.

答案：A，为什么？

14.   Thirty years ago, the percentage of the British people who vacationed in foreign countries was very small compared with the large percentage of the British population who travel abroad for vacations now. Foreign travel is, and always has been, expensive from Britain. Therefore, British people must have, on average, more money to spend on vacations now than they did 30 years ago.

The argument requires assuming which one of the following?

(A) If foreign travel had been less expensive 30 years ago, British people would still not have had enough money to take vacation abroad.

(B) If travel to Britain were less expensive, more people of other countries would travel to Britain for their vacations.

(C) If the percentage of British people vacationing abroad was lower 30 years ago, then the British people of 30 years ago must have spent more money on domestic vacations.

(D) If more of the British people 30 years ago had had enough money to vacation abroad, more would have done so.（D）

(E) If British people are now wealthier than they were 30 years ago, then they must have more money to spend on vacations now than they did 30 years ago.

答案：D，为什么？

Question #1

B - doesn't help counter the argument because it merely states that
today's word processing equipment inherited its keyboards from the
standard typewriter

C - Irrelevant for obvious reasons

D - Irrelevant to the argument

E - The argument is that why with today's technological advancement do
people still use standard keyboard.  This answer choice gives a
potential solution to the paradox yet it does not counter the argument.

Question #2

A - This is merely a speculation.  I think this would have been a
trap because it takes people's economic bias into account.  

B - This refers to foreign countries, thus rendering the choice irrelevant

C - This is another speculation, talking about domestic vacation.
It's easier to go down this way because that's what our intuition would
tell us.  

E - The way I take this is that it's almost like the last sentence of the argument, not an assumption



I hope this helps.
