input question: Question: "What characteristic set Pietro's paintings aside from other artists back in the great period of Roman mosaic art?" Context: "The last great period of Roman mosaic art was the 12th13th century when Rome developed its own distinctive artistic style, free from the strict rules of eastern tradition and with a more realistic portrayal of figures in the space. Well-known works of this period are the floral mosaics of the Basilica di San Clemente, the facade of Santa Maria in Trastevere and San Paolo fuori le Mura. The beautiful apse mosaic of Santa Maria in Trastevere (1140) depicts Christ and Mary sitting next to each other on the heavenly throne, the first example of this iconographic scheme. A similar mosaic, the Coronation of the Virgin, decorates the apse of Santa Maria Maggiore. It is a work of Jacopo Torriti from 1295. The mosaics of Torriti and Jacopo da Camerino in the apse of San Giovanni in Laterano from 128894 were thoroughly restored in 1884. The apse mosaic of San Crisogono is attributed to Pietro Cavallini, the greatest Roman painter of the 13th century. Six scenes from the life of Mary in Santa Maria in Trastevere were also executed by Cavallini in 1290. These mosaics are praised for their realistic portrayal and attempts of perspective. There is an interesting mosaic medaillon from 1210 above the gate of the church of San Tommaso in Formis showing Christ enthroned between a white and a black slave. The church belonged to the Order of the Trinitarians which was devoted to ransoming Christian slaves." Answer:???
output answer: their realistic portrayal and attempts of perspective

Question: "When was the Russian Navy destroyed?" Context: "When Russia invaded the Turkish Balkans in 1853, fears of Russian dominance in the Mediterranean and Middle East led Britain and France to invade the Crimean Peninsula to destroy Russian naval capabilities. The ensuing Crimean War (185456), which involved new techniques of modern warfare, and was the only global war fought between Britain and another imperial power during the Pax Britannica, was a resounding defeat for Russia. The situation remained unresolved in Central Asia for two more decades, with Britain annexing Baluchistan in 1876 and Russia annexing Kirghizia, Kazakhstan, and Turkmenistan. For a while it appeared that another war would be inevitable, but the two countries reached an agreement on their respective spheres of influence in the region in 1878 and on all outstanding matters in 1907 with the signing of the Anglo-Russian Entente. The destruction of the Russian Navy by the Japanese at the Battle of Port Arthur during the Russo-Japanese War of 190405 also limited its threat to the British." Answer:
----
Answer: during the Russo-Japanese War

Q: Question: "What happened first in the 3rd year of the 1400s?" Context: "With the extension of Turkish dominion into the Balkans, the strategic conquest of Constantinople became a crucial objective. The empire had managed to control nearly all former Byzantine lands surrounding the city, but in 1402 the Byzantines were temporarily relieved when the Turco-Mongol leader Timur, founder of the Timurid Empire, invaded Anatolia from the east. In the Battle of Ankara in 1402, Timur defeated the Ottoman forces and took Sultan Bayezid I as a prisoner, throwing the empire into disorder. The ensuing civil war lasted from 1402 to 1413 as Bayezid's sons fought over succession. It ended when Mehmed I emerged as the sultan and restored Ottoman power, bringing an end to the Interregnum, also known as the Fetret Devri." Answer:

[Q]: Question: "What was established in the eighty-fourth year of the twentieth century?" Context: "Sacerdotalis caelibatus (Latin for "Of the celibate priesthood"), promulgated on 24 June 1967, defends the Catholic Church's tradition of priestly celibacy in the West. This encyclical was written in the wake of Vatican II, when the Catholic Church was questioning and revising many long-held practices. Priestly celibacy is considered a discipline rather than dogma, and some had expected that it might be relaxed. In response to these questions, the Pope reaffirms the discipline as a long-held practice with special importance in the Catholic Church. The encyclical Sacerdotalis caelibatus from 24 June 1967, confirms the traditional Church teaching, that celibacy is an ideal state and continues to be mandatory for Roman Catholic priests. Celibacy symbolizes the reality of the kingdom of God amid modern society. The priestly celibacy is closely linked to the sacramental priesthood. However, during his pontificate Paul VI was considered generous in permitting bishops to grant laicization of priests who wanted to leave the sacerdotal state, a position which was drastically reversed by John Paul II in 1980 and cemented in the 1983 Canon Law that only the pope can in exceptional circumstances grant laicization." Answer:
****
[A]: Canon Law
