[Q]: 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.

Passage:In 1987, Townsend wrote, directed and produced Hollywood Shuffle, a satire based on the hardships and obstacles that black actors undergo in the film industry.

[Q]: Question: Is Atocha railway station located in Spain's capital? Passage:The 1977 Atocha massacre, a part of neo-fascist terrorism in Spain, was an attack during the Spanish transition to democracy after the death of Franco in 1975, killing five and injuring four. It was committed on January 24, 1977, in an office located on 55 Atocha Street near the Atocha railway station in Madrid, where specialists in labour law, members of the Workers' Commissions (Comisiones Obreras, CCOO) trade union, and of the then-clandestine Communist Party of Spain (PCE) had gathered. The next day, the massacre was defended by a group calling itself Alianza Apostólica Anticomunista (literally Apostolic Anticommunist Alliance, abbreviated Triple A or AAA). The suspects arrested were close to Blas Piñar's Fuerza Nueva far-right party, the Falange-JONS and the Franco Guard. The indignation brought about by the killings accelerated the legalisation of the Communist party, which took place in Easter 1977. On March 24, 1984, the Italian daily Il Messaggero stated that, possibly, Italian neo-fascists had taken part in the shootings, pointing toward some kind of "Black International". This allegation was confirmed by a report from the Italian CESIS, which confirmed that Carlo Cicuttini, who was also involved in the Peteano massacre, took part in the Atocha massacre.
