Problem: Edmund Burke:

Burke's Reflections sparked a pamphlet war. Thomas Paine penned the Rights of Man in 1791 as a response to Burke; Mary Wollstonecraft published A Vindication of the Rights of Men and James Mackintosh wrote Vindiciae Gallicae. Mackintosh was the first to see the Reflections as "the manifesto of a Counter Revolution". Mackintosh later agreed with Burke's views, remarking in December 1796 after meeting him, that Burke was "minutely and accurately informed, to a wonderful exactness, with respect to every fact relating to the French Revolution". Mackintosh later said: "Burke was one of the first thinkers as well as one of the greatest orators of his time. He is without parallel in any age, excepting perhaps Lord Bacon and Cicero; and his works contain an ampler store of political and moral wisdom than can be found in any other writer whatever".

Who wrote 'The Rights of Man'?

A: Thomas Paine

Problem: At her Silver Jubilee in 1977, the crowds and celebrations were genuinely enthusiastic, but in the 1980s, public criticism of the royal family increased, as the personal and working lives of Elizabeth's children came under media scrutiny. Elizabeth's popularity sank to a low point in the 1990s. Under pressure from public opinion, she began to pay income tax for the first time, and Buckingham Palace was opened to the public. Discontent with the monarchy reached its peak on the death of Diana, Princess of Wales, though Elizabeth's personal popularity and support for the monarchy rebounded after her live television broadcast to the world five days after Diana's death.
What decade between now and the 1970s has been the high point for Elizabeth's popularity?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In addition to the cathedral, Strasbourg houses several other medieval churches that have survived the many wars and destructions that have plagued the city: the Romanesque Eglise Saint-Etienne, partly destroyed in 1944 by Allied bombing raids, the part Romanesque, part Gothic, very large Eglise Saint-Thomas with its Silbermann organ on which Wolfgang Amadeus Mozart and Albert Schweitzer played, the Gothic Eglise protestante Saint-Pierre-le-Jeune with its crypt dating back to the seventh century and its cloister partly from the eleventh century, the Gothic Eglise Saint-Guillaume with its fine early-Renaissance stained glass and furniture, the Gothic Eglise Saint-Jean, the part Gothic, part Art Nouveau Eglise Sainte-Madeleine, etc. The Neo-Gothic church Saint-Pierre-le-Vieux Catholique (there is also an adjacent church Saint-Pierre-le-Vieux Protestant) serves as a shrine for several 15th-century wood worked and painted altars coming from other, now destroyed churches and installed there for public display. Among the numerous secular medieval buildings, the monumental Ancienne Douane (old custom-house) stands out.
What style of building is the Ancienne Douane?
A: unanswerable

Context and question: The ideas of the Italian Renaissance were slow to cross the Alps into northern Europe, but important artistic innovations were made also in the Low Countries. Though not as previously believed the inventor of oil painting, Jan van Eyck was a champion of the new medium, and used it to create works of great realism and minute detail. The two cultures influenced each other and learned from each other, but painting in the Netherlands remained more focused on textures and surfaces than the idealized compositions of Italy.
Where wasn't the focus of paintings on textures and surfaces?
Answer: unanswerable

Question: While the majority of flowers are perfect or hermaphrodite (having both pollen and ovule producing parts in the same flower structure), flowering plants have developed numerous morphological and physiological mechanisms to reduce or prevent self-fertilization. Heteromorphic flowers have short carpels and long stamens, or vice versa, so animal pollinators cannot easily transfer pollen to the pistil (receptive part of the carpel). Homomorphic flowers may employ a biochemical (physiological) mechanism called self-incompatibility to discriminate between self and non-self pollen grains. In other species, the male and female parts are morphologically separated, developing on different flowers.
Is there an answer to this question: What happens to male and female parts of carpels that are hermaphrodites?

Answer: unanswerable

Problem: History of science:

Mathematics: From the earliest the Chinese used a positional decimal system on counting boards in order to calculate. To express 10, a single rod is placed in the second box from the right. The spoken language uses a similar system to English: e.g. four thousand two hundred seven. No symbol was used for zero. By the 1st century BC, negative numbers and decimal fractions were in use and The Nine Chapters on the Mathematical Art included methods for extracting higher order roots by Horner's method and solving linear equations and by Pythagoras' theorem. Cubic equations were solved in the Tang dynasty and solutions of equations of order higher than 3 appeared in print in 1245 AD by Ch'in Chiu-shao. Pascal's triangle for binomial coefficients was described around 1100 by Jia Xian.

What advanced mathematical methods did the Tang dynasty have?
---
A:
Cubic equations
