Q: Passage: In a publication of 1941, Norman Tindale, together with the American anthropologist Joseph Birdsell, published a paper suggesting that there were 12 Negrito tribes living on the coastal and rainforest areas around Cairns. The idea had been developed by Birdsell during field work in 1937-8. They were characterized by very short stature, curly hair, and yellowy-brown skin. Six of them were Dyirbal speakers, such as the Jirrbal, Girramay, Gulngai and Djiru within the Murray Upper/Tully Area. Of the others, located further north beyond Cairns, two spoke varieties of Djabugay, and three spoke dialects of Yidin. The remaining tribe were the Mbabaram, whom Tindale took to be strong evidence for his hypothesis because their language, in so far as it had been reported, diverged substantially from the surrounding tongues, and appeared to be wholly atypical, compared to the standard Australian aboriginal languages.

Q: Passage: "Tobacco", an eighteen-minute segment about the tobacco industry, was delivered by John Oliver on February 15, 2015, during the second episode of Last Week Tonight second season. Oliver introduces the topic of tobacco smoking by showing video clips of "trusted newsmen, cartoon characters, and cowboys in TV commercials" who are smoking cigarettes. He says that the cowboy in the clip is Marlboro Man, a figure used in advertising campaigns for Marlboro cigarettes, and notes that four of the actors portraying Marlboro Man have died from lung cancer or smoking-related illnesses. Oliver says that cigarette smoking is no longer as prevalent in the United States because of, among other things, mandatory warnings on all cigarette boxes and a ban on TV advertisements for cigarettes. The comedian says that tobacco executives adamantly refused to acknowledge the potential drawbacks to smoking, despite strong evidence to prove these drawbacks. He shows a video of Joseph Cullman, the former CEO of the tobacco company Philip Morris International (PMI), saying that "some women would prefer having smaller babies" in response to a reporter's comment that pregnant women who smoke will give birth to smaller babies as a result. Even so, the restrictions on smoking advertisements contributed to a decline in smoking rates among American adults, as only 18% of adults smoked in 2014, compared to 43% of adults in 1965.

Q: 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. Zenobe 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.
