Problem: Strasbourg:

City transportation in Strasbourg includes the futurist-looking Strasbourg tramway that opened in 1994 and is operated by the regional transit company Compagnie des Transports Strasbourgeois (CTS), consisting of 6 lines with a total length of 55.8 km (34.7 mi). The CTS also operates a comprehensive bus network throughout the city that is integrated with the trams. With more than 500 km (311 mi) of bicycle paths, biking in the city is convenient and the CTS operates a cheap bike-sharing scheme named Vélhop'. The CTS, and its predecessors, also operated a previous generation of tram system between 1878 and 1960, complemented by trolleybus routes between 1939 and 1962.

Problem: Wieman's words proved prophetic. Though Process and Reality has been called "arguably the most impressive single metaphysical text of the twentieth century," it has been little-read and little-understood, partly because it demands – as Isabelle Stengers puts it – "that its readers accept the adventure of the questions that will separate them from every consensus." Whitehead questioned western philosophy's most dearly held assumptions about how the universe works, but in doing so he managed to anticipate a number of 21st century scientific and philosophical problems and provide novel solutions.
 What effect did Whitehead have on the past of metaphysics?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
What percentage of cotton is cellulose?
A: 90%


Context and question: The first political factions, cohering around a basic, if fluid, set of principles emerged from the Exclusion Crisis and Glorious Revolution in late-17th-century England. The Whigs supported Protestant constitutional monarchy against absolute rule and the Tories, originating in the Royalist (or "Cavalier") faction of the English Civil War, were conservative royalist supporters of a strong monarchy as a counterbalance to the republican tendencies of Whigs, who were the dominant political faction for most of the first half of the 18th century; they supported the Hanoverian succession of 1715 against the Jacobite supporters of the deposed Roman Catholic Stuart dynasty and were able to purge Tory politicians from important government positions after the failed Jacobite rising of 1715. The leader of the Whigs was Robert Walpole, who maintained control of the government in the period 1721–1742; his protégé was Henry Pelham (1743–1754).
Who was the dominate political party for the first half of the 18th century?
Answer: Whigs

The largest and bloodiest American battle came at Okinawa, as the U.S. sought airbases for 3,000 B-29 bombers and 240 squadrons of B-17 bombers for the intense bombardment of Japan's home islands in preparation for a full-scale invasion in late 1945. The Japanese, with 115,000 troops augmented by thousands of civilians on the heavily populated island, did not resist on the beaches—their strategy was to maximize the number of soldier and Marine casualties, and naval losses from Kamikaze attacks. After an intense bombardment the Americans landed on 1 April 1945 and declared victory on 21 June. The supporting naval forces were the targets for 4,000 sorties, many by Kamikaze suicide planes. U.S. losses totaled 38 ships of all types sunk and 368 damaged with 4,900 sailors killed. The Americans suffered 75,000 casualties on the ground; 94% of the Japanese soldiers died along with many civilians.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many U.S. ships were lost at Okinawa?
Ah, so..
38
