PROBLEM: Passage: In 1863 he married Helen Magruder, daughter of Commodore George Allan Magruder, of the United States Navy. They had one son, James. They had two daughters, Ella Campbell Scarlett who studied medicine at London School of Medicine for Women and the Royal Free Hospital and became the first female doctor in the state of Bloemfontein, South Africa, and Evelina, who married Major Henry Haverfield, was a suffragette and an aid worker during World War I. One of the two main family estates at this time (the other being the house that is today Inverlochy Castle Hotel) was Abinger Hall, at the foot of the North Downs in Abinger, Surrey. The third baron sold it in 1867 to a Mr Gwynne, who soon thereafter sold it to become the family seat of the statistician recently created first Lord Farrer, who rebuilt the house on that land.

PROBLEM: Passage: The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

PROBLEM: Passage: Reitherman was hired at Walt Disney Productions on May 21, 1933, and his first project was working as an animator on the Silly Symphonies cartoon, Funny Little Bunnies. Reitherman continued to work on a number of Disney shorts, including The Band Concert, Music Land, and Elmer Elephant. He animated the Slave in the Magic Mirror in Snow White and the Seven Dwarfs (1937). His next assignments was animating Monstro in Pinocchio (1940), the climactic dinosaur fight in Igor Stravinsky's The Rite of Spring in Fantasia (1940), and several scenes of Timothy Q. Mouse in Dumbo (1941). Starting in 1942, Reitherman had left Disney to serve in World War II for the United States Air Force, earning the Distinguished Flying Cross after serving in Africa, China, India and the South Pacific. He was discharged in February 1946 having earned the rank of Major. Reitherman rejoined Disney in April 1947, where he animated the Headless Horseman chase in "The Legend of Sleepy Hollow" section in The Adventures of Ichabod and Mr. Toad (1949). Around this same time, he had claimed he was instrumental in helping Walt Disney commit to producing Cinderella (1950). Reitherman recalled, "I just went in his office which I rarely did, and I said, 'Gee, that looks great. We ought to do do it.' It might have been a little nudge to say, 'Hey, let's get going again and let's do a feature'." On Cinderella, he was the directing animator of the sequence in which Jaq and Gus laboriously push and pull the key up the stairs to Cinderella. On Alice in Wonderland (1951), he animated the scene in which the White Rabbit's home is destroyed by an enlarged Alice. On Peter Pan (1953), he animated the scene of Captain Hook attempting to escape the crocodile. For Lady and the Tramp (1955), Reitherman animated the alley dog fight sequence and Tramp's fight with the rat in the nursery room.
