Problem: Cubism:

Architectural interest in Cubism centered on the dissolution and reconstitution of three-dimensional form, using simple geometric shapes, juxtaposed without the illusions of classical perspective. Diverse elements could be superimposed, made transparent or penetrate one another, while retaining their spatial relationships. Cubism had become an influential factor in the development of modern architecture from 1912 (La Maison Cubiste, by Raymond Duchamp-Villon and André Mare) onwards, developing in parallel with architects such as Peter Behrens and Walter Gropius, with the simplification of building design, the use of materials appropriate to industrial production, and the increased use of glass.

Problem: Plants and various other groups of photosynthetic eukaryotes collectively known as "algae" have unique organelles known as chloroplasts. Chloroplasts are thought to be descended from cyanobacteria that formed endosymbiotic relationships with ancient plant and algal ancestors. Chloroplasts and cyanobacteria contain the blue-green pigment chlorophyll a. Chlorophyll a (as well as its plant and green algal-specific cousin chlorophyll b)[a] absorbs light in the blue-violet and orange/red parts of the spectrum while reflecting and transmitting the green light that we see as the characteristic colour of these organisms. The energy in the red and blue light that these pigments absorb is used by chloroplasts to make energy-rich carbon compounds from carbon dioxide and water by oxygenic photosynthesis, a process that generates molecular oxygen (O2) as a by-product.
What color is chlorophyll?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Today, USD notes are made from cotton fiber paper, unlike most common paper, which is made of wood fiber. U.S. coins are produced by the United States Mint. U.S. dollar banknotes are printed by the Bureau of Engraving and Printing and, since 1914, have been issued by the Federal Reserve. The "large-sized notes" issued before 1928 measured 7.42 inches (188 mm) by 3.125 inches (79.4 mm); small-sized notes, introduced that year, measure 6.14 inches (156 mm) by 2.61 inches (66 mm) by 0.0043 inches (0.11 mm). When the current, smaller sized U.S. currency was introduced it was referred to as Philippine-sized currency because the Philippines had previously adopted the same size for its legal currency.
How long do the current reserves measure?
A: unanswerable


Context and question: The TV rights agreement between the Premier League and Sky has faced accusations of being a cartel, and a number of court cases have arisen as a result. An investigation by the Office of Fair Trading in 2002 found BSkyB to be dominant within the pay TV sports market, but concluded that there were insufficient grounds for the claim that BSkyB had abused its dominant position. In July 1999 the Premier League's method of selling rights collectively for all member clubs was investigated by the UK Restrictive Practices Court, who concluded that the agreement was not contrary to the public interest.
Agreements between UK Restrictive Practices Court and the Premier League have been accused of being what?
Answer: unanswerable


Question: In September 1939, Britain entered the Second World War, which lasted until 1945. During the war, many of London's children were evacuated to avoid the frequent aerial bombing. The suggestion by senior politician Lord Hailsham that the two princesses should be evacuated to Canada was rejected by Elizabeth's mother, who declared, "The children won't go without me. I won't leave without the King. And the King will never leave." Princesses Elizabeth and Margaret stayed at Balmoral Castle, Scotland, until Christmas 1939, when they moved to Sandringham House, Norfolk. From February to May 1940, they lived at Royal Lodge, Windsor, until moving to Windsor Castle, where they lived for most of the next five years. At Windsor, the princesses staged pantomimes at Christmas in aid of the Queen's Wool Fund, which bought yarn to knit into military garments. In 1940, the 14-year-old Elizabeth made her first radio broadcast during the BBC's Children's Hour, addressing other children who had been evacuated from the cities. She stated: "We are trying to do all we can to help our gallant sailors, soldiers and airmen, and we are trying, too, to bear our share of the danger and sadness of war. We know, every one of us, that in the end all will be well."
Is there an answer to this question: In what year did the BBC start Children's Hour?

Answer: unanswerable


Problem: Liberal Party of Australia:

Socially, while liberty and freedom of enterprise form the basis of its beliefs, elements of the party have wavered between what is termed "small-l liberalism" and social conservatism. Historically, Liberal Governments have been responsible for the carriage of a number of notable "socially liberal" reforms, including the opening of Australia to multiethnic immigration under Menzies and Harold Holt; Holt's 1967 Referendum on Aboriginal Rights; Sir John Gorton's support for cinema and the arts; selection of the first Aboriginal Senator, Neville Bonner, in 1971; and Malcolm Fraser's Aboriginal Land Rights Act 1976. A West Australian Liberal, Ken Wyatt, became the first Indigenous Australian elected to the House of Representatives in 2010.

In what year was the first Aboriginal Senator elected?
