Problem: Canadian football:

The Burnside rules closely resembling American Football that were incorporated in 1903 by The ORFU, was an effort to distinguish it from a more rugby-oriented game. The Burnside Rules had teams reduced to 12 men per side, introduced the Snap-Back system, required the offensive team to gain 10 yards on three downs, eliminated the Throw-In from the sidelines, allowed only six men on the line, stated that all goals by kicking were to be worth two points and the opposition was to line up 10 yards from the defenders on all kicks. The rules were an attempt to standardize the rules throughout the country. The CIRFU, QRFU and CRU refused to adopt the new rules at first. Forward passes were not allowed in the Canadian game until 1929, and touchdowns, which had been five points, were increased to six points in 1956, in both cases several decades after the Americans had adopted the same changes. The primary differences between the Canadian and American games stem from rule changes that the American side of the border adopted but the Canadian side did not (originally, both sides had three downs, goal posts on the goal lines and unlimited forward motion, but the American side modified these rules and the Canadians did not). The Canadian field width was one rule that was not based on American rules, as the Canadian game played in wider fields and stadiums that were not as narrow as the American stadiums.

In what year did the American game allow forward passes?

Context and question: As briefly discussed in Unicode Technical Note #26, "In terms of implementation issues, any attempt at a unification of Latin, Greek, and Cyrillic would wreak havoc [and] make casing operations an unholy mess, in effect making all casing operations context sensitive […]". In other words, while the shapes of letters like A, B, E, H, K, M, O, P, T, X, Y and so on are shared between the Latin, Greek, and Cyrillic alphabets (and small differences in their canonical forms may be considered to be of a merely typographical nature), it would still be problematic for a multilingual character set or a font to provide only a single codepoint for, say, uppercase letter B, as this would make it quite difficult for a wordprocessor to change that single uppercase letter to one of the three different choices for the lower-case letter, b (Latin), β (Greek), or в (Cyrillic). Without letter case, a "unified European alphabet" – such as ABБCГDΔΕZЄЗFΦGHIИJ…Z, with an appropriate subset for each language – is feasible; but considering letter case, it becomes very clear that these alphabets are rather distinct sets of symbols.
Although there are challenges a unified European alphabet is feasible even in the absence of which common language rule?
Answer: letter case


Question: In 1853 the Russian Empire on behalf of the Slavic Balkan states began to question the very existence of the Ottoman Empire. The result was the Crimean War, 1853–1856, in which the British Empire and the French Empire supported the Ottoman Empire in its struggle against the incursions of the Russian Empire. Eventually, the Ottoman Empire lost control of the Balkan region.
Is there an answer to this question: When was the Crimean War?

Answer: 1853–1856


QUES: Gautama first went to study with famous religious teachers of the day, and mastered the meditative attainments they taught. But he found that they did not provide a permanent end to suffering, so he continued his quest. He next attempted an extreme asceticism, which was a religious pursuit common among the śramaṇas, a religious culture distinct from the Vedic one. Gautama underwent prolonged fasting, breath-holding, and exposure to pain. He almost starved himself to death in the process. He realized that he had taken this kind of practice to its limit, and had not put an end to suffering. So in a pivotal moment he accepted milk and rice from a village girl and changed his approach. He devoted himself to anapanasati meditation, through which he discovered what Buddhists call the Middle Way (Skt. madhyamā-pratipad): a path of moderation between the extremes of self-indulgence and self-mortification.[web 2][web 3]
