Input: Read this: He moved rapidly. First, he promoted Confucian orthodoxy and reversed what he saw as his father's laxness by cracking down on unorthodox sects and by decapitating an anti-Manchu writer his father had pardoned. In 1723 he outlawed Christianity and expelled Christian missionaries, though some were allowed to remain in the capital. Next, he moved to control the government. He expanded his father's system of Palace Memorials which brought frank and detailed reports on local conditions directly to the throne without being intercepted by the bureaucracy, and created a small Grand Council of personal advisors which eventually grew into the emperor's de facto cabinet for the rest of the dynasty. He shrewdly filled key positions with Manchu and Han Chinese officials who depended on his patronage. When he began to realize that the financial crisis was even greater than he had thought, Yongzheng rejected his father's lenient approach to local landowning elites and mounted a campaign to enforce collection of the land tax. The increased revenues were to be used for "money to nourish honesty" among local officials and for local irrigation, schools, roads, and charity. Although these reforms were effective in the north, in the south and lower Yangzi valley, where Kangxi had wooed the elites, there were long established networks of officials and landowners. Yongzheng dispatched experienced Manchu commissioners to penetrate the thickets of falsified land registers and coded account books, but they were met with tricks, passivity, and even violence. The fiscal crisis persisted.
Question: When did Yongzheng ban christianity?

Input: Read this: The Appalachian belt includes, with the ranges enumerated above, the plateaus sloping southward to the Atlantic Ocean in New England, and south-eastward to the border of the coastal plain through the central and southern Atlantic states; and on the north-west, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys, including The Great Appalachian Valley, which in the southerly sections divides the mountain system into two unequal portions, but in the northernmost lies west of all the ranges possessing typical Appalachian features, and separates them from the Adirondack group. The mountain system has no axis of dominating altitudes, but in every portion the summits rise to rather uniform heights, and, especially in the central section, the various ridges and intermontane valleys have the same trend as the system itself. None of the summits reaches the region of perpetual snow.
Question: What is the climate like on the summits?

Output: None of the summits reaches the region of perpetual snow.

Input: Read this: The High Middle Ages was a period of great religious movements. Besides the Crusades and monastic reforms, people sought to participate in new forms of religious life. New monastic orders were founded, including the Carthusians and the Cistercians. The latter especially expanded rapidly in their early years under the guidance of Bernard of Clairvaux (d. 1153). These new orders were formed in response to the feeling of the laity that Benedictine monasticism no longer met the needs of the laymen, who along with those wishing to enter the religious life wanted a return to the simpler hermetical monasticism of early Christianity, or to live an Apostolic life. Religious pilgrimages were also encouraged. Old pilgrimage sites such as Rome, Jerusalem, and Compostela received increasing numbers of visitors, and new sites such as Monte Gargano and Bari rose to prominence.
Question: When did Bernard of Clairvaux die?

Output: 1153
