Problem: Mosaic:

Non-religious Umayyad mosaic works were mainly floor panels which decorated the palaces of the caliphs and other high-ranking officials. They were closely modeled after the mosaics of the Roman country villas, once common in the Eastern Mediterranean. The most superb example can be found in the bath house of Hisham's Palace, Palestine which was made around 744. The main panel depicts a large tree and underneath it a lion attacking a deer (right side) and two deers peacefully grazing (left side). The panel probably represents good and bad governance. Mosaics with classical geometric motifs survived in the bath area of the 8th-century Umayyad palace complex in Anjar, Lebanon. The luxurious desert residence of Al-Walid II in Qasr al-Hallabat (in present-day Jordan) was also decorated with floor mosaics that show a high level of technical skill. The best preserved panel at Hallabat is divided by a Tree of Life flanked by "good" animals on one side and "bad" animals on the other. Among the Hallabat representations are vine scrolls, grapes, pomegranates, oryx, wolves, hares, a leopard, pairs of partridges, fish, bulls, ostriches, rabbits, rams, goats, lions and a snake. At Qastal, near Amman, excavations in 2000 uncovered the earliest known Umayyad mosaics in present-day Jordan, dating probably from the caliphate of Abd al-Malik ibn Marwan (685–705). They cover much of the floor of a finely decorated building that probably served as the palace of a local governor. The Qastal mosaics depict geometrical patterns, trees, animals, fruits and rosettes. Except for the open courtyard, entrance and staircases, the floors of the entire palace were covered in mosaics.

What were the floor panels of the caliphs and high ranking officials modeled after?

A: Roman country villas


Problem: In May 1985, Gorbachev delivered a speech in Leningrad advocating reforms and an anti-alcohol campaign to tackle widespread alcoholism. Prices on vodka, wine, and beer were raised in order to make these drinks more expensive and a disincentive to consumers, and the introduction of rationing. Unlike most forms of rationing intended to conserve scarce goods, this was done to restrict sales with the overt goal of curtailing drunkenness. Gorbachev's plan also included billboards promoting sobriety, increased penalties for public drunkenness, and to censor drinking scenes from old movies. Although this program was not a direct copycat of Tsar Nicholas II's outright prohibition during World War I, Gorbachev faced the same adverse economic reaction as did the last Tsar. The disincentivization of alcohol consumption was a serious blow to the state budget according to Alexander Yakovlev, who noted annual collections of alcohol taxes decreased by 100 billion rubles. Alcohol production migrated to the black market, or through moonshining as some made "bathtub vodka" with homegrown potatoes. Poorer, less educated Russians resorted to drinking unhealthy substitutes such as nail polish, rubbing alcohol or men's cologne, which only served to be an additional burden on Russia's healthcare sector due to the subsequent poisoning cases. The purpose of these reforms, however, was to prop up the existing centrally planned economy, unlike later reforms, which tended toward market socialism.
When was Gorbachev's speech addressing alcohol abuse?

Melbourne is experiencing high population growth, generating high demand for housing. This housing boom has increased house prices and rents, as well as the availability of all types of housing. Subdivision regularly occurs in the outer areas of Melbourne, with numerous developers offering house and land packages. However, after 10 years[when?] of planning policies to encourage medium-density and high-density development in existing areas with greater access to public transport and other services, Melbourne's middle and outer-ring suburbs have seen significant brownfields redevelopment.
What effect has the housing boom had on house prices and rents?
A: increased


Context and question: The period saw several important technical innovations, like the principle of linear perspective found in the work of Masaccio, and later described by Brunelleschi. Greater realism was also achieved through the scientific study of anatomy, championed by artists like Donatello. This can be seen particularly well in his sculptures, inspired by the study of classical models. As the centre of the movement shifted to Rome, the period culminated in the High Renaissance masters da Vinci, Michelangelo and Raphael.
Who rejected the scientific study of anatomy for the benefit of art?
Answer: unanswerable


Question: Near New Haven there is the static inverter plant of the HVDC Cross Sound Cable. There are three PureCell Model 400 fuel cells placed in the city of New Haven—one at the New Haven Public Schools and newly constructed Roberto Clemente School, one at the mixed-use 360 State Street building, and one at City Hall. According to Giovanni Zinn of the city's Office of Sustainability, each fuel cell may save the city up to $1 million in energy costs over a decade. The fuel cells were provided by ClearEdge Power, formerly UTC Power.
Is there an answer to this question: What static inverter plant lies near New Haven? 

Answer: HVDC Cross Sound Cable
