Problem: Middle Ages:

Christianity was a major unifying factor between Eastern and Western Europe before the Arab conquests, but the conquest of North Africa sundered maritime connections between those areas. Increasingly the Byzantine Church differed in language, practices, and liturgy from the western Church. The eastern church used Greek instead of the western Latin. Theological and political differences emerged, and by the early and middle 8th century issues such as iconoclasm, clerical marriage, and state control of the church had widened to the extent that the cultural and religious differences were greater than the similarities. The formal break came in 1054, when the papacy and the patriarchy of Constantinople clashed over papal supremacy and excommunicated each other, which led to the division of Christianity into two churchesthe western branch became the Roman Catholic Church and the eastern branch the Orthodox Church.

Over what issue did the eastern and western churches split?
---
A: papal supremacy

Problem: Asphalt:

About 40,000,000 tons were produced in 1984[needs update]. It is obtained as the "heavy" (i.e., difficult to distill) fraction. Material with a boiling point greater than around 500 C is considered asphalt. Vacuum distillation separates it from the other components in crude oil (such as naphtha, gasoline and diesel). The resulting material is typically further treated to extract small but valuable amounts of lubricants and to adjust the properties of the material to suit applications. In a de-asphalting unit, the crude asphalt is treated with either propane or butane in a supercritical phase to extract the lighter molecules, which are then separated. Further processing is possible by "blowing" the product: namely reacting it with oxygen. This step makes the product harder and more viscous.

How many tons were produced in 1927?

A: unanswerable

Problem: Norfolk Island:

Sixty-two percent of islanders are Christians. After the death of the first chaplain Rev G. H. Nobbs in 1884, a Methodist church was formed and in 1891 a Seventh-day Adventist congregation led by one of Nobbs' sons. Some unhappiness with G. H. Nobbs, the more organised and formal ritual of the Church of England service arising from the influence of the Melanesian Mission, decline in spirituality, the influence of visiting American whalers, literature sent by Christians overseas impressed by the Pitcairn story, and the adoption of Seventh-day Adventism by the descendants of the mutineers still on Pitcairn, all contributed to these developments. The Roman Catholic Church began work in 1957 and in the late 1990s a group left the former Methodist (then Uniting Church) and formed a charismatic fellowship. In 2011, 34 percent of the ordinary residents identified as Anglican, 13 percent as Uniting Church, 12 percent as Roman Catholic and three percent as Seventh-day Adventist. Nine percent were from other religions. Twenty four percent had no religion, and seven percent did not indicate a religion. Typical ordinary congregations in any church do not exceed 30 local residents as of 2010[update]. The three older denominations have good facilities. Ministers are usually short-term visitors.
