QUES: C trigraphs were created to solve this problem for ANSI C, although their late introduction and inconsistent implementation in compilers limited their use. Many programmers kept their computers on US-ASCII, so plain-text in Swedish, German etc. (for example, in e-mail or Usenet) contained "{, }" and similar variants in the middle of words, something those programmers got used to. For example, a Swedish programmer mailing another programmer asking if they should go for lunch, could get "N{ jag har sm|rg}sar." as the answer, which should be "Na jag har smorgasar." meaning "No I've got sandwiches."

Why was their use limited?
What is the answer?
ANS: their late introduction and inconsistent implementation in compilers
QUES: The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.

What did the FDA study discover?
What is the answer?
ANS: unanswerable
QUES: Eisenhower responded to the French defeat with the formation of the SEATO (Southeast Asia Treaty Organization) Alliance with the U.K., France, New Zealand and Australia in defense of Vietnam against communism. At that time the French and Chinese reconvened Geneva peace talks; Eisenhower agreed the U.S. would participate only as an observer. After France and the Communists agreed to a partition of Vietnam, Eisenhower rejected the agreement, offering military and economic aid to southern Vietnam. Ambrose argues that Eisenhower, by not participating in the Geneva agreement, had kept the U.S out of Vietnam; nevertheless, with the formation of SEATO, he had in the end put the U.S. back into the conflict.
