Input: Read this: Lamps designed for different voltages have different luminous efficacy. For example, a 100-watt, 120-volt lamp will produce about 17.1 lumens per watt. A lamp with the same rated lifetime but designed for 230 V would produce only around 12.8 lumens per watt, and a similar lamp designed for 30 volts (train lighting) would produce as much as 19.8 lumens per watt. Lower voltage lamps have a thicker filament, for the same power rating. They can run hotter for the same lifetime before the filament evaporates.
Question: What watt lamp can produce 17.3 lumens per watt?

Output: unanswerable

QUES: Avignon was the seat of the papacy from 1309 to 1376. With the return of the Pope to Rome in 1378, the Papal State developed into a major secular power, culminating in the morally corrupt papacy of Alexander VI. Florence grew to prominence amongst the Italian city-states through financial business, and the dominant Medici family became important promoters of the Renaissance through their patronage of the arts. Other city states in northern Italy also expanded their territories and consolidated their power, primarily Milan and Venice. The War of the Sicilian Vespers had by the early 14th century divided southern Italy into an Aragon Kingdom of Sicily and an Anjou Kingdom of Naples. In 1442, the two kingdoms were effectively united under Aragonese control.

In what year were the two southern Italian kingdoms separated?
What is the answer?
ANS: unanswerable

QUES: The power of parliament to pass bills was often thwarted by monarchs. Charles I dissolved parliament in 1629, after it passed motions critical of and bills seeking to restrict his arbitrary exercise of power. During the eleven years of personal rule that followed, Charles performed legally dubious actions, such as raising taxes without parliament's approval. After the English Civil War, it was accepted that parliament should be summoned to meet regularly, but it was still commonplace for monarchs to refuse royal assent to bills. In 1678, Charles II withheld his assent from a bill "for preserving the Peace of the Kingdom by raising the Militia, and continuing them in Duty for Two and Forty Days," suggesting that he, not parliament, should control the militia. The last Stuart monarch, Anne, similarly withheld on 11 March 1708, on the advice of her ministers, her assent from a bill for the settling of Militia in Scotland. No monarch has since withheld royal assent on a bill passed by the British parliament.
Which ruler removed parliament in 1629?

ANS: Charles I

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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did Yongzheng ban christianity?
Ah, so.. 1723

Question: In 2006, after almost 80 years, NBC Universal sold all Walt Disney-produced Oswald cartoons, along with the rights to the character himself, back to Disney.
