Indicate your choice as `a` for Yes or `b` for No.

Question: What materials are used as fuel in the type of furnace first used in the Weald to produce cast iron? Passage:Sir Francis Pettit Smith of Kent invented the screw propeller. Faversham Oyster Fishery is the oldest company in the world. Maidenhead Railway Bridge is known for its flat arch, built in 1839 with 39-metre spans. The Wealden iron industry in the Weald was the site of the first blast furnace in Britain in 1491, and produced much of Britain's cast iron until the 1770s. Portsmouth Block Mills were the site of the world's first metal machine tools, built for the manufacture of wooden pulleys, invented by Henry Maudslay, and the site of the world's first industrial assembly line in 1803. South Foreland Lighthouse on 8 December 1858 was the world's first lighthouse with electric light, with the first type of industrial electrical generator made by Frederick Hale Holmes, from work he had carried out with Floris Nollet of Belgium, and 36 permanent magnets. By 1880, of the ten lighthouses with electric light, five were in the UK. From the lighthouse in 1899, the first international radio broadcast to France was made. Zénobe Gramme of Belgium made a much better design in 1870 with self-excitation of magnets, and the first modern dynamo. North Foreland Lighthouse was the UK's last-manned lighthouse until 1998.

Question: How old was the military engineer who scouted around Leith during the siege? Passage:The English King Henry VIII, angered by the Scots reneging on the initial agreement, made war on Scotland in 1544–1549, a period which the writer Sir Walter Scott later christened the "Rough Wooing". In May 1544 an English army landed at Granton and captured Leith to land heavy artillery for an assault on Edinburgh Castle, but withdrew after burning the town and the Palace of Holyrood over three days. Three years later, following another English invasion and victory at Pinkie Cleugh in 1547, the English attempted to establish a "pale" within Scotland. Leith was of prime strategic importance because of its vital role as Edinburgh's port, handling its foreign trade and essential supplies. The English arrived in Leith on 11 September 1547 and camped on Leith Links. The military engineer Richard Lee scouted around the town on 12 September looking to see if it could be made defensible. On 14 September the English began digging a trench on the south-east side of Leith near the Firth of Forth. William Patten wrote that the work was done as much for exercise as for defence, since the army only stayed for five days.

Question: Who is the current mayor of Slobe's birthplace? Passage:Slobe was born in Pittsburgh to a well-to-do Jewish family, and grew up in Chicago, enrolling in the School of the Art Institute of Chicago at 16; by 19 she was exhibiting paintings and winning prizes. She began exhibiting sculpture as well by the late 1930s, and came eventually to be known more as a sculptor than as a painter. In 1939 and 1940 she worked for the Works Progress Administration, creating art and teaching in a number of states, including Oregon. She became acquainted at this point with George Perle, whom she married in 1940; in 1942 the couple joined the Socialist Workers Party, and she took the pseudonym "Laura Gray". She was soon tasked with assisting in the organization of automotive workers, and it was at this time that she began her cartooning career. Encouraged to submit drawings to The Militant, her first appeared in the paper on March 4, 1944; she went on to become the paper's staff artist, submitting at least one cartoon almost weekly for the rest of her life. These drawings, which have been compared to the work of Boardman Robinson, Hugo Gellert, and Robert Minor, would be published in Trotskyist publications around the world. Some of her cartoons on the subject of civil rights would also be published in the African-American press.
