Problem: Gregorian calendar:

In addition to the change in the mean length of the calendar year from 365.25 days (365 days 6 hours) to 365.2425 days (365 days 5 hours 49 minutes 12 seconds), a reduction of 10 minutes 48 seconds per year, the Gregorian calendar reform also dealt with the accumulated difference between these lengths. The canonical Easter tables were devised at the end of the third century, when the vernal equinox fell either on 20 March or 21 March depending on the year's position in the leap year cycle. As the rule was that the full moon preceding Easter was not to precede the equinox the equinox was fixed at 21 March for computational purposes and the earliest date for Easter was fixed at 22 March. The Gregorian calendar reproduced these conditions by removing ten days.

What was reduced by forty-eight minutes and ten seconds?

A: unanswerable


Problem: Throughout the war, the King and Queen provided morale-boosting visits throughout the United Kingdom, visiting bomb sites, munitions factories, and troops. The King visited military forces abroad in France in December 1939, North Africa and Malta in June 1943, Normandy in June 1944, southern Italy in July 1944, and the Low Countries in October 1944. Their high public profile and apparently indefatigable determination secured their place as symbols of national resistance. At a social function in 1944, Chief of the Imperial General Staff Sir Alan Brooke, revealed that every time he met Field Marshal Bernard Montgomery he thought he was after his job. The King replied: "You should worry, when I meet him, I always think he's after mine!"
In what month in 1944 did the King meet Sir Alan Brooke?

Early reports of Europeans reaching this area include those of the Venetian Alvise Cadamosto's voyage of 1455, the 1479–1480 voyage by Flemish-French trader Eustache de la Fosse, and Diogo Cão. In the 1480s this Portuguese explorer reached the Congo River and the lands of Bakongo, setting up the foundations of modern Angola, some 4200 km down the African coast from Guinea-Bissau.
What river did Diogo Cao reach in the 1480's?
A: Congo River


Context and question: Women could not be professed to the Dominican religious life before the age of thirteen. The formula for profession contained in the Constitutions of Montargis Priory (1250) demands that nuns pledge obedience to God, the Blessed Virgin, their prioress and her successors according to the Rule of St. Augustine and the institute of the order, until death. The clothing of the sisters consisted of a white tunic and scapular, a leather belt, a black mantle, and a black veil. Candidates to profession were tested to reveal whether they were actually married women who had merely separated from their husbands. Their intellectual abilities were also tested. Nuns were to be silent in places of prayer, the cloister, the dormitory, and refectory. Silence was maintained unless the prioress granted an exception for a specific cause. Speaking was allowed in the common parlor, but it was subordinate to strict rules, and the prioress, subprioress or other senior nun had to be present.
What type of veil must the sisters wear?
Answer: black


Question: The greater advances of the Soviet space program at the time allowed their space program to achieve other significant firsts, including the first EVA "spacewalk" and the first mission performed by a crew in shirt-sleeves. Gemini took a year longer than planned to accomplish its first flight, allowing the Soviets to achieve another first, launching Voskhod 1 on October 12, 1964, the first spacecraft with a three-cosmonaut crew. The USSR touted another technological achievement during this mission: it was the first space flight during which cosmonauts performed in a shirt-sleeve-environment. However, flying without spacesuits was not due to safety improvements in the Soviet spacecraft's environmental systems; rather this innovation was accomplished because the craft's limited cabin space did not allow for spacesuits. Flying without spacesuits exposed the cosmonauts to significant risk in the event of potentially fatal cabin depressurization. This feat would not be repeated until the US Apollo Command Module flew in 1968; this later mission was designed from the outset to safely transport three astronauts in a shirt-sleeve environment while in space.
Is there an answer to this question: The US Apollo Command Module flew without spacesuits in what year?

Answer: 1968


As a teenager, he was greatly troubled by the Metaphysics of Aristotle, which he could not understand until he read al-Farabi's commentary on the work. For the next year and a half, he studied philosophy, in which he encountered greater obstacles. In such moments of baffled inquiry, he would leave his books, perform the requisite ablutions, then go to the mosque, and continue in prayer till light broke on his difficulties. Deep into the night, he would continue his studies, and even in his dreams problems would pursue him and work out their solution. Forty times, it is said, he read through the Metaphysics of Aristotle, till the words were imprinted on his memory; but their meaning was hopelessly obscure, until one day they found illumination, from the little commentary by Farabi, which he bought at a bookstall for the small sum of three dirhams. So great was his joy at the discovery, made with the help of a work from which he had expected only mystery, that he hastened to return thanks to God, and bestowed alms upon the poor.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What helped Avicenna understand the Metaphysics of Aristotle?
Ah, so..
al-Farabi's commentary
