Problem: There is a close connection between machine learning and compression: a system that predicts the posterior probabilities of a sequence given its entire history can be used for optimal data compression (by using arithmetic coding on the output distribution) while an optimal compressor can be used for prediction (by finding the symbol that compresses best, given the previous history). This equivalence has been used as a justification for using data compression as a benchmark for "general intelligence."
What has been used as a benchmark for "general intelligence"?
The answer is the following: data compression

Problem: The Qing emperors were generally adept at poetry and often skilled in painting, and offered their patronage to Confucian culture. The Kangxi and Qianlong Emperors, for instance, embraced Chinese traditions both to control them and to proclaim their own legitimacy. The Kangxi Emperor sponsored the Peiwen Yunfu, a rhyme dictionary published in 1711, and the Kangxi Dictionary published in 1716, which remains to this day an authoritative reference. The Qianlong Emperor sponsored the largest collection of writings in Chinese history, the Siku Quanshu, completed in 1782. Court painters made new versions of the Song masterpiece, Zhang Zeduan's Along the River During the Qingming Festival whose depiction of a prosperous and happy realm demonstrated the beneficence of the emperor. The emperors undertook tours of the south and commissioned monumental scrolls to depict the grandeur of the occasion. Imperial patronage also encouraged the industrial production of ceramics and Chinese export porcelain.
What was the rhyme dictionary called that was published by Kangxi?
The answer is the following: Peiwen Yunfu

Problem: Everton were founder members of the Premier League in 1992, but struggled to find the right manager. Howard Kendall had returned in 1990 but could not repeat his previous success, while his successor, Mike Walker, was statistically the least successful Everton manager to date. When former Everton player Joe Royle took over in 1994 the club's form started to improve; his first game in charge was a 2–0 victory over derby rivals Liverpool. Royle dragged Everton clear of relegation, leading the club to the FA Cup for the fifth time in its history, defeating Manchester United 1–0 in the final.
What year did former Everton player Joe Royle take over managing the club?
The answer is the following: 1994

Problem: The rivalries between the Arab tribes had caused unrest in the provinces outside Syria, most notably in the Second Muslim Civil War of 680–692 CE and the Berber Revolt of 740–743 CE. During the Second Civil War, leadership of the Umayyad clan shifted from the Sufyanid branch of the family to the Marwanid branch. As the constant campaigning exhausted the resources and manpower of the state, the Umayyads, weakened by the Third Muslim Civil War of 744–747 CE, were finally toppled by the Abbasid Revolution in 750 CE/132 AH. A branch of the family fled across North Africa to Al-Andalus, where they established the Caliphate of Córdoba, which lasted until 1031 before falling due to the Fitna of al-Ándalus.
In what year CE did the Second Muslim Civil War end?
The answer is the following:
692
