Problem: From the mid-1950s through the 1960s, in the U.S. the common home record player or "stereo" (after the introduction of stereo recording) would typically have had these features: a three- or four-speed player (78, 45, 33 1⁄3, and sometimes 16 2⁄3 rpm); with changer, a tall spindle that would hold several records and automatically drop a new record on top of the previous one when it had finished playing, a combination cartridge with both 78 and microgroove styli and a way to flip between the two; and some kind of adapter for playing the 45s with their larger center hole. The adapter could be a small solid circle that fit onto the bottom of the spindle (meaning only one 45 could be played at a time) or a larger adaptor that fit over the entire spindle, permitting a stack of 45s to be played.
What feature of 45s required an adapter in most home stereos?
The answer is the following: larger center hole.


One mustn't overlook the doctrines of Galen: In use from his life in the 1st century AD until the 17th century, it was heresy to disagree with him for 1500 years. Galen was physician to gladiators in Pergamon, and in Rome, physician to Marcus Aurelius and the three emperors who succeeded him. Most of Galen's teachings were gathered and enhanced in the late 11th century by Benedictine monks at the School of Salerno in Regimen sanitatis Salernitanum, which still had users in the 17th century. Galen believed in the bodily humours of Hippocrates, and he taught that pneuma is the source of life. Four elements (earth, air, fire and water) combine into "complexion", which combines into states (the four temperaments: sanguine, phlegmatic, choleric, and melancholic). The states are made up of pairs of attributes (hot and moist, cold and moist, hot and dry, and cold and dry), which are made of four humours: blood, phlegm, green (or yellow) bile, and black bile (the bodily form of the elements). Galen thought that for a person to have gout, kidney stones, or arthritis was scandalous, which Gratzer likens to Samuel Butler's Erehwon (1872) where sickness is a crime.
What did each pair of attributes supposedly consist of?
four humours


Input: Detroit
In November 1973, the city elected Coleman Young as its first black mayor. After taking office, Young emphasized increasing racial diversity in the police department. Young also worked to improve Detroit's transportation system, but tension between Young and his suburban counterparts over regional matters was problematic throughout his mayoral term. In 1976, the federal government offered $600 million for building a regional rapid transit system, under a single regional authority. But the inability of Detroit and its suburban neighbors to solve conflicts over transit planning resulted in the region losing the majority of funding for rapid transit. Following the failure to reach an agreement over the larger system, the City moved forward with construction of the elevated downtown circulator portion of the system, which became known as the Detroit People Mover.

Who was the first black mayor of Detroit?
Output: Coleman Young


Input: Article: John XXIII died of peritonitis caused by a perforated stomach at 19:49 local time on 3 June 1963 at the age of 81, ending a historic pontificate of four years and seven months. He died just as a Mass for him finished in Saint Peter's Square below, celebrated by Luigi Traglia. After he died, his brow was ritually tapped to see if he was dead, and those with him in the room said prayers. Then the room was illuminated, thus informing the people of what had happened. He was buried on 6 June in the Vatican grottos. Two wreaths, placed on the two sides of his tomb, were donated by the prisoners of the Regina Coeli prison and the Mantova jail in Verona. On 22 June 1963, one day after his friend and successor Pope Paul VI was elected, the latter prayed at his tomb.

Now answer this question: What day was he buried?

Output: 6 June


Article: While Mont Blanc was first climbed in 1786, most of the Alpine four-thousanders were climbed during the first half of the 19th century; the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism. Karl Blodig (1859–1956) was among the first to successfully climb all the major 4,000 m peaks. He completed his series of ascents in 1911.

Question: What did the ascent of the Matterhorn mark?
Ans: the end of the golden age of alpinism


Input: Elizabeth II
The Suez crisis and the choice of Eden's successor led in 1957 to the first major personal criticism of the Queen. In a magazine, which he owned and edited, Lord Altrincham accused her of being "out of touch". Altrincham was denounced by public figures and slapped by a member of the public appalled by his comments. Six years later, in 1963, Macmillan resigned and advised the Queen to appoint the Earl of Home as prime minister, advice that she followed. The Queen again came under criticism for appointing the prime minister on the advice of a small number of ministers or a single minister. In 1965, the Conservatives adopted a formal mechanism for electing a leader, thus relieving her of involvement.

What did Lord Altrincham accuse Elizabeth of being?
Output:
out of touch
