Problem: Cotton:

Production capacity in Britain and the United States was improved by the invention of the cotton gin by the American Eli Whitney in 1793. Before the development of cotton gins, the cotton fibers had to be pulled from the seeds tediously by hand. By the late 1700s a number of crude ginning machines had been developed. However, to produce a bale of cotton required over 600 hours of human labor, making large-scale production uneconomical in the United States, even with the use of humans as slave labor. The gin that Whitney manufactured (the Holmes design) reduced the hours down to just a dozen or so per bale. Although Whitney patented his own design for a cotton gin, he manufactured a prior design from Henry Odgen Holmes, for which Holmes filed a patent in 1796. Improving technology and increasing control of world markets allowed British traders to develop a commercial chain in which raw cotton fibers were (at first) purchased from colonial plantations, processed into cotton cloth in the mills of Lancashire, and then exported on British ships to captive colonial markets in West Africa, India, and China (via Shanghai and Hong Kong).

Before the use of the cotton gin, how were bales separated?

Problem: Romanesque art, especially metalwork, was at its most sophisticated in Mosan art, in which distinct artistic personalities including Nicholas of Verdun (d. 1205) become apparent, and an almost classical style is seen in works such as a font at Liège, contrasting with the writhing animals of the exactly contemporary Gloucester Candlestick. Large illuminated bibles and psalters were the typical forms of luxury manuscripts, and wall-painting flourished in churches, often following a scheme with a Last Judgement on the west wall, a Christ in Majesty at the east end, and narrative biblical scenes down the nave, or in the best surviving example, at Saint-Savin-sur-Gartempe, on the barrel-vaulted roof.
What year saw the death of Nicholas of Verdun?

Answer: 1205


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.
What are the Majority Leader's duties in Westminster?
A: unanswerable

Question: Another objection is that it is not always possible to demonstrate falsehood definitively, especially if one is using statistical criteria to evaluate a null hypothesis. More generally it is not always clear, if evidence contradicts a hypothesis, that this is a sign of flaws in the hypothesis rather than of flaws in the evidence. However, this is a misunderstanding of what Popper's philosophy of science sets out to do. Rather than offering a set of instructions that merely need to be followed diligently to achieve science, Popper makes it clear in The Logic of Scientific Discovery that his belief is that the resolution of conflicts between hypotheses and observations can only be a matter of the collective judgment of scientists, in each individual case.
Is there an answer to this question: Who wrote a set of instructions that merely need to be followed diligently to achieve science?

Answer: unanswerable


QUES: In China, urbanization increased as the population grew and as the division of labor grew more complex. Large urban centers, such as Nanjing and Beijing, also contributed to the growth of private industry. In particular, small-scale industries grew up, often specializing in paper, silk, cotton, and porcelain goods. For the most part, however, relatively small urban centers with markets proliferated around the country. Town markets mainly traded food, with some necessary manufactures such as pins or oil. Despite the xenophobia and intellectual introspection characteristic of the increasingly popular new school of neo-Confucianism, China under the early Ming dynasty was not isolated. Foreign trade and other contacts with the outside world, particularly Japan, increased considerably. Chinese merchants explored all of the Indian Ocean, reaching East Africa with the treasure voyages of Zheng He.

During The Early MIng Dynasty Chinese merchants explored all of what?
What is the answer?
ANS:
Indian Ocean
