PROBLEM: Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden? Passage:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

PROBLEM: Question: What present day country was Pontus? Passage:According to the Georgian chronicles, Nana was "from a Greek territory, from Pontus, the daughter of Oligotos" whom Mirian married after his first wife died (in 292 according to Cyril Toumanoff). Nana bore Mirian two sons: Rev II, Varaz-Bakur and a daughter who married Peroz, the first Mihranid dynast of Gugark. Pontus here may refer to the Bosporan Kingdom, then a client state of the Roman Empire. Toumanoff has assumed that the name of Nana's father might have been a Georgian corruption of "Olympius" or "Olympus", a Bosporan dynast whose son Aurelius Valerius Sogus Olympianus, a Roman governor of Theodosia, is known from a Greek inscription of 306 dedicated to "the Most High God" on the occasion of the building of the Jewish "prayer house". Alternatively, Christian Settipani identifies Nana as a younger daughter of Theothorses, a Bosporan king.

PROBLEM: Question: How many years was the Papal residence in the Lateran Palace before being moved to the Quirinal Palace? Passage:With the increasing chaos and disorder leading to the collapse of the Roman Empire in 476, the popes assumed more and more civil authority first in Rome and in the surrounding territories. Rome became the center of the Catholic Church and the capital city of the Papal States; consequently, a great number of churches, convents and other religious buildings were erected in the city, sometimes above the ruins of older pre-Christian sites of worship. Churches proliferated during the Renaissance, when the Rome's most notable churches were built (this includes St. Peter's basilica on the Vatican Hill (the largest church in the world) and the city cathedral of St. John at the Lateran. The Papacy established its residence first in the Lateran Palace, then in the Quirinal Palace. When Rome was annexed by force to the newly unified Kingdom of Italy In 1870, Pope Pius IX retired to the Vatican, proclaiming himself a prisoner of the Savoy monarchy and leading to decades of conflict between the neonate state and the Catholic Church. This was resolved in 1929, when the Lateran Treaty were signed in Rome, establishing the right for the Holy See to govern the Vatican City as an independent, sovereign state. The patron saints of Rome remain Saint Peter and Saint Paul (or, as they are collectively referred to in this context, "the most holy Saints Peter and Paul"), both celebrated on June 29.
