Input: Read this: The most impressive and famous of Sumerian buildings are the ziggurats, large layered platforms which supported temples. Sumerian cylinder seals also depict houses built from reeds not unlike those built by the Marsh Arabs of Southern Iraq until as recently as 400 CE. The Sumerians also developed the arch, which enabled them to develop a strong type of dome. They built this by constructing and linking several arches. Sumerian temples and palaces made use of more advanced materials and techniques,[citation needed] such as buttresses, recesses, half columns, and clay nails.
Question: What is the most impressive and famous style of Sumerian buildings?

Output: the ziggurats

QUES: Despite early victories, Pyrrhus found his position in Italy untenable. Rome steadfastly refused to negotiate with Pyrrhus as long as his army remained in Italy. Facing unacceptably heavy losses from each encounter with the Roman army, Pyrrhus withdrew from the peninsula (hence the term "Pyrrhic victory"). In 275 BC, Pyrrhus again met the Roman army at the Battle of Beneventum. While Beneventum was indecisive, Pyrrhus realised his army had been exhausted and reduced by years of foreign campaigns. Seeing little hope for further gains, he withdrew completely from Italy.

What did Rome refuse to do in their relations with Pyrrhus?
What is the answer?
ANS: negotiate

QUES: Brass, which is an alloy of copper and zinc, has been used since at least the 10th century BC in Judea and by the 7th century BC in Ancient Greece. Zinc metal was not produced on a large scale until the 12th century in India and was unknown to Europe until the end of the 16th century. The mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc. Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow".
What two metals are mixed to create Brass?

ANS: copper and zinc

T. Gilmartin, (Professor of History, Maynooth, 1890), writes in Church History, Vol. 1, Ch XVII: By Constantius's order, the sole ruler of The Roman Empire at the death of his brother Constans, the Council of Arles in 353, was held, which was presided over by Vincent, Bishop of Capua, in the name of Pope Liberius. The fathers terrified of the threats of the Emperor, an avowed Arian, they consented to the condemnation of Athanasius. The Pope refused to accept their decision, and requested the Emperor to hold another Council, in which the charges against Athanasius could be freely investigated. To this Constantius consented, for he felt able to control it, at Milan. Milan was named as the place, here three hundred bishops assembled, most from the West, only a few from the East, in 355. They met in the Church of Milan. Shortly, the Emperor ordered them to a hall in the Imperial Palace, thus ending any free debate. He presented an Arian formula of faith for their acceptance. He threatened any who refused with exile and death. All, with the exception of Dionysius (bishop of Milan), and the two Papal Legates, viz., Eusebius of Vercelli and Lucifer of Cagliari, consented to the Arian Creed and the condemnation of Athanasius. Those who refused were sent into exile. The decrees were forwarded to the Pope for approval, but were rejected, because of the violence to which the bishops were subjected.

Ah, so.. unanswerable

Question: Monastic reform inspired change in the secular church. The ideals that it was based upon were brought to the papacy by Pope Leo IX (pope 10491054), and provided the ideology of the clerical independence that led to the Investiture Controversy in the late 11th century. This involved Pope Gregory VII (pope 107385) and Emperor Henry IV, who initially clashed over episcopal appointments, a dispute that turned into a battle over the ideas of investiture, clerical marriage, and simony. The emperor saw the protection of the Church as one of his responsibilities as well as wanting to preserve the right to appoint his own choices as bishops within his lands, but the papacy insisted on the Church's independence from secular lords. These issues remained unresolved after the compromise of 1122 known as the Concordat of Worms. The dispute represents a significant stage in the creation of a papal monarchy separate from and equal to lay authorities. It also had the permanent consequence of empowering German princes at the expense of the German emperors.
Try to answer this question if possible: When did the reign of Pope Leo IX begin?
Answer: 1049

Input: Read this: USB is a serial bus, using four shielded wires for the USB 2.0 variant: two for power (VBUS and GND), and two for differential data signals (labelled as D+ and D in pinouts). Non-Return-to-Zero Inverted (NRZI) encoding scheme is used for transferring data, with a sync field to synchronize the host and receiver clocks. D+ and D signals are transmitted on a twisted pair, providing half-duplex data transfers for USB 2.0. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification.
Question: What is USB?

Output:
a serial bus
