PROBLEM: Passage: In 1982, Dome built the RC82 as their first effort in the new Group C category of sports car racing. The chassis was built by March Engineering, whilst the engine was a 3.3-litre Cosworth DFL V8 engine. Dome, with sponsorship from Amada, debuted the car at the 1982 6 Hours of Silverstone, and selected Chris Craft, Raul Boesel and Eliseo Salazar to drive it. It would not prove to be a successful debut, as the car succumbed to fuel pressure issues after 116 laps. Dome then entered Craft and Salazar at the 24 Hours of Le Mans, but the suspension mounting failed after 85 laps, and the team were forced to retire. The RC82 was not used again until the 1983 24 Hours of Le Mans; Nick Mason joined the team, but the car lasted 75 laps before succumbing to clutch failure. Following the race, the RC83 made its debut in the 1000 km of Fuji, with the factory phasing out the RC82.

PROBLEM: Passage: In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efe people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.

PROBLEM: Passage: Anderson was born in Edinburgh in 1832. He studied medicine at the University of Edinburgh, graduating with an MD in 1853. While at University he became interested in botany, and earned a gold medal for the best local collection of plants, and assisted in arranging the Indian herbarium. In 1854 he entered the Bengal medical service, and went to Calcutta. Subsequently he went to Delhi, where he was actively engaged during the mutiny, returning to Calcutta in 1858. His health failing, he came home, and, the steamer being detained at Aden for some days, he made an interesting collection of the plants of that region, upon which he based his 'Florula Adenensis,' published in 1860. About this time he returned to India, taking temporary charge of the Calcutta Botanic Garden during the absence of Dr Thomas Thomson, whom he afterwards succeeded as director. His brother, John Anderson was a zoologist.
