Problem: Friedrich Hayek:

From 1962 until his retirement in 1968, he was a professor at the University of Freiburg, West Germany, where he began work on his next book, Law, Legislation and Liberty. Hayek regarded his years at Freiburg as "very fruitful". Following his retirement, Hayek spent a year as a visiting professor of philosophy at the University of California, Los Angeles, where he continued work on Law, Legislation and Liberty, teaching a graduate seminar by the same name and another on the philosophy of social science. Primary drafts of the book were completed by 1970, but Hayek chose to rework his drafts and finally brought the book to publication in three volumes in 1973, 1976 and 1979.

When was the final volume of Law, Legislation and Liberty released?

A: 1979

Problem: Beginning in 1979, Nigerians participated in a brief return to democracy when Olusegun Obasanjo transferred power to the civilian regime of Shehu Shagari. The Shagari government became viewed as corrupt and incompetent by virtually all sectors of Nigerian society. The military coup of Muhammadu Buhari shortly after the regime's fraudulent re-election in 1984 was generally viewed as a positive development. Buhari promised major reforms, but his government fared little better than its predecessor. His regime was overthrown by another military coup in 1985.
How did Nigerians view the Shagari administration?

Answer: corrupt and incompetent

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the U.S., a push for revisions of the FD&C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored the need for more comprehensive regulation and provided the driving force for the passage of new laws.
What were the major issues that needed to be addressed?
A: advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry

Context and question: Typically, the warmest day of the year (19712000) will achieve a temperature of 26.6 C (80 F), although in June 1976 the temperature reached 31.6 C (89 F), the site record. On average, 4.25 days of the year will report a maximum temperature of 25.1 C (77 F) or above. During the winter half of the year, the coldest night will typically fall to 4.1 C (25 F) although in January 1979 the temperature fell to 8.8 C (16 F). Typically, 18.6 nights of the year will register an air frost.

Problem: Pain:

In 1968 Ronald Melzack and Kenneth Casey described pain in terms of its three dimensions: "sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion). They theorized that pain intensity (the sensory discriminative dimension) and unpleasantness (the affective-motivational dimension) are not simply determined by the magnitude of the painful stimulus, but "higher" cognitive activities can influence perceived intensity and unpleasantness. Cognitive activities "may affect both sensory and affective experience or they may modify primarily the affective-motivational dimension. Thus, excitement in games or war appears to block both dimensions of pain, while suggestion and placebos may modulate the affective-motivational dimension and leave the sensory-discriminative dimension relatively undisturbed." (p. 432) The paper ends with a call to action: "Pain can be treated not only by trying to cut down the sensory input by anesthetic block, surgical intervention and the like, but also by influencing the motivational-affective and cognitive factors as well." (p. 435)
