Vladimir the Great (980–1015) introduced Christianity with his own baptism and, by decree, that of all the inhabitants of Kiev and beyond. Kievan Rus' reached its greatest extent under Yaroslav I (1019–1054); his sons assembled and issued its first written legal code, the Rus' Justice, shortly after his death.

Input: Read this: The reinforcement type defines two major classes of materials - woven and non-woven. Woven reinforcements are cheaper, but the high dielectric constant of glass may not be favorable for many higher-frequency applications. The spatially nonhomogeneous structure also introduces local variations in electrical parameters, due to different resin/glass ratio at different areas of the weave pattern. Nonwoven reinforcements, or materials with low or no reinforcement, are more expensive but more suitable for some RF/analog applications.
Question: Which is the more expensive reinforcement type?

Output: non-woven


Input: Read this: 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.
Question: Why did the Bishops condemn Athanasius?

threats of the Emperor
