Problem: The growing likelihood of war in Europe dominated the early reign of George VI. The King was constitutionally bound to support Prime Minister Neville Chamberlain's appeasement of Hitler. However, when the King and Queen greeted Chamberlain on his return from negotiating the Munich Agreement in 1938, they invited him to appear on the balcony of Buckingham Palace with them. This public association of the monarchy with a politician was exceptional, as balcony appearances were traditionally restricted to the royal family. While broadly popular among the general public, Chamberlain's policy towards Hitler was the subject of some opposition in the House of Commons, which led historian John Grigg to describe the King's behaviour in associating himself so prominently with a politician as "the most unconstitutional act by a British sovereign in the present century".
What was the House of Commons policy towards Hitler?

Problem: Formerly, men not wearing military uniform wore knee breeches of an 18th-century design. Women's evening dress included obligatory trains and tiaras or feathers in their hair (or both). The dress code governing formal court uniform and dress has progressively relaxed. After World War I, when Queen Mary wished to follow fashion by raising her skirts a few inches from the ground, she requested a lady-in-waiting to shorten her own skirt first to gauge the king's reaction. King George V was horrified, so the queen kept her hemline unfashionably low. Following their accession in 1936, King George VI and his consort, Queen Elizabeth, allowed the hemline of daytime skirts to rise. Today, there is no official dress code. Most men invited to Buckingham Palace in the daytime choose to wear service uniform or lounge suits; a minority wear morning coats, and in the evening, depending on the formality of the occasion, black tie or white tie.
From what century were men's knee breeches worn at Buckingham designed in?

Answer: 18th-century design


Problem: 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 fibres are used in the bleaching process?
