[EX Q]: 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.

[EX Q]: Passage: The first archaeological investigation of the site was carried out in 1964. In that year, the site was noted during an archaeological survey of the region directed by Maurits N. van Loon of the Oriental Institute of the University of Chicago, and a small sounding was made. In 1965, a more extensive excavation was carried out, again under the direction of Van Loon. Between 1971 and 1974, work on the site was resumed by a team of the French Centre national de la recherche scientifique (CNRS) directed by Jacques Cauvin. All excavations were part of the larger international – and eventually UNESCO-coordinated – effort to investigate as many archaeological sites as possible in the area that would be flooded by Lake Assad, the reservoir of the Tabqa Dam, which was being built at that time. The filling of Lake Assad eventually led to the flooding of Mureybet in 1976. Although the site is now submerged and no longer accessible, the material that has been retrieved during the excavations continues to generate new research. This material is currently stored at the National Museum of Aleppo and the Institute de Préhistoire Orientale in Jalès-Berrias in France.

[EX Q]: Passage: Beyond an occasional visit from a band of nomad Mongols, this region of the Pe-shan swelling is entirely uninhabited. And yet it was from this region, according to Grigory Grum-Grshimailo (1889-1890 explorer), that the Yue-chi (Yuezhi), a nomadic people akin to the Tibetans, proceeded when, towards the middle of the 2nd century BC, they moved westwards and settled near Lake Issyk-kul; and from here proceeded also the Shanshani, or people who some two thousand years ago founded the state of Shanshan or Lofi-lan. The ruins of this town were discovered by Sven Hedin in the desert of Lop in 1901. Here, says the Russian explorer, the Huns gathered strength, as also did the Turks (Ch. Tukiu) in the 6th century, and the Uighur tribes and the rulers of the Tangut kingdom. But after Genghis Khan, in the 12th century, drew away the peoples of this region, and no others came to take their place, the country went out of cultivation and eventually became the barren desert it is now. During the Hun time, and probably into the Middle Ages, the present desert was a lush steppe grassland able to support sustainable seasonal nomadic horse husbandry on a large scale.
