Problem: Geological history of Earth:

The Cambrian is a major division of the geologic timescale that begins about 541.0 ± 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.

What were the continents of the Cambrian area believed to have formerly been a part of?
---
A: Pannotia


Problem: The tour in March 1987[citation needed] of Knuckles, Jefferson, Fingers Inc. (Heard) and Adonis as the DJ International Tour boosted house in the UK. Following the number-one success of MARRS' "Pump Up The Volume" in October, the years 1987 to 1989 also saw UK acts such as The Beatmasters, Krush, Coldcut, Yazz, Bomb The Bass, S-Express, and Italy's Black Box opening the doors to a house music onslaught on the UK charts. Early British house music quickly set itself apart from the original Chicago house sound;[citation needed] many of the early hits were based on sample montage, rap was often used for vocals (far more than in the US),[citation needed] and humor was frequently an important element.
What tour boosted house in the US in the late 80s?

Following similar conflicts over modernism, the Southern Baptist Convention adhered to conservative theology as its official position. Two new Baptist groups were formed by moderate Southern Baptists who disagreed with the direction in which the Southern Baptist Convention was heading: the Alliance of Baptists in 1987 and the Cooperative Baptist Fellowship in 1991. Members of both groups originally identified as Southern Baptist, but over time the groups "became permanent new families of Baptists."
What groups were formed by moderate Southern Baptists?
A: the Alliance of Baptists in 1987 and the Cooperative Baptist Fellowship in 1991


Context and question: Meanwhile, the authorities in Glasgow, Scotland successfully petitioned the government to pass the Glasgow Police Act establishing the City of Glasgow Police in 1800. Other Scottish towns soon followed suit and set up their own police forces through acts of parliament. In Ireland, the Irish Constabulary Act of 1822 marked the beginning of the Royal Irish Constabulary. The Act established a force in each barony with chief constables and inspectors general under the control of the civil administration at Dublin Castle. By 1841 this force numbered over 8,600 men.
What was Ireland's police force not called?
Answer: unanswerable


Question: In the CFL, if the game is tied at the end of regulation play, then each team is given an equal number of chances to break the tie. A coin toss is held to determine which team will take possession first; the first team scrimmages the ball at the opponent's 35-yard line and advances through a series of downs until it scores or loses possession. If the team scores a touchdown, starting with the 2010 season, it is required to attempt a 2-point conversion. The other team then scrimmages the ball at the same 35-yard line and has the same opportunity to score. After the teams have completed their possessions, if one team is ahead, then it is declared the winner; otherwise, the two teams each get another chance to score, scrimmaging from the other 35-yard line. After this second round, if there is still no winner, during the regular season the game ends as a tie. In a playoff or championship game, the teams continue to attempt to score from alternating 35-yard lines, until one team is leading after both have had an equal number of possessions.
Is there an answer to this question: In which year did the CFL begin requiring teams to attempt 2-point conversions after scoring in a tie-breaking situation?

Answer: 2010


QUES: Vladimir had been prince of Novgorod when his father Sviatoslav I died in 972. He was forced to flee to Scandinavia in 976 after his half-brother Yaropolk had murdered his other brother Oleg and taken control of Rus. In Scandinavia, with the help of his relative Earl Håkon Sigurdsson, ruler of Norway, Vladimir assembled a Viking army and reconquered Novgorod and Kiev from Yaropolk. As Prince of Kiev, Vladimir's most notable achievement was the Christianization of Kievan Rus', a process that began in 988. The Primary Chronicle states that when Vladimir had decided to accept a new faith instead of the traditional idol-worship (paganism) of the Slavs, he sent out some of his most valued advisors and warriors as emissaries to different parts of Europe. They visited the Christians of the Latin Rite, the Jews, and the Muslims before finally arriving in Constantinople. They rejected Islam because, among other things, it prohibited the consumption of alcohol, and Judaism because the god of the Jews had permitted his chosen people to be deprived of their country. They found the ceremonies in the Roman church to be dull. But at Constantinople, they were so astounded by the beauty of the cathedral of Hagia Sophia and the liturgical service held there that they made up their minds there and then about the faith they would like to follow. Upon their arrival home, they convinced Vladimir that the faith of the Byzantine Rite was the best choice of all, upon which Vladimir made a journey to Constantinople and arranged to marry Princess Anna, the sister of Byzantine emperor Basil II.
