[EX Q]: Question: How long had Central States Wrestling been in business the year Robertson won the NWA Central States Television Championship? Passage:Robertson moved to Central States Wrestling, where he won the majority of his titles. On October 22, 1981, he won the NWA Central States Television Championship with a victory over Gene Lewis. He lost the belt to Oliver Humperdink later that year but soon regained it in a rematch. On February 18, 1982, however, he dropped the belt back to Lewis. This allowed Robertson to focus on the NWA Central States Tag Team Championship, which he won a total of five times. His first reign came in October 1981 when he teamed with Rufus R. Jones to defeat Buzz Tyler and James J. Dillon. His next reign came in March 1982 when he teamed with Steve Regal to win the belts from Roger Kirby and Jerry Valiant. The title changed hands twice more that month, as Kirby and Valiant quickly regained the title only to drop it back to Robertson and Regal. Two months later, Kirby and Valiant won the belts back again. Robertson found a new partner, however, and won the championship by teaming with Hercules Hernandez in August. The reign lasted less than a month, but Robertson and Hernandez held the belts one final time after another victory in September 1982. The following year, Robertson's main success came as a singles wrestler. On February 10, 1983, he won the NWA Central States Heavyweight Championship with a victory over Manny Fernandez. He lost the belt to Bob Brown two months later but regained it in a rematch the following week. Robertson's final title reign ended when he dropped the title to Race on June 2, 1983.

[EX Q]: Question: Was the TV series in which Colin Tapley costarred with Donald Gray still on the air during World War II? Passage:In 1933, film company Paramount Pictures wanted to re-juvenate and diversify its contract players, and launched a competition known as the "Search for Beauty"; heats took place in nations across the English-speaking world. Elred Tidbury entered in his native South Africa and was selected with Lucille du Toit, a dental nurse from Pretoria, as one of the winners. Colin Tapley, who would later appear opposite Gray in the TV series Mark Saber, was the New Zealand male winner. In total, there were 30 finalists worldwide, who were screen-tested over six weeks at the end of 1933. Of the 30, bit player contracts were awarded to 10, and Tidbury was selected as the overall male winner with a bonus of US$1,000, with which he bought a car. The overall female winner was Scottish actress Gwenllian Gill, who later followed Tidbury to Britain and became engaged to him; however, their engagement was broken off during the Second World War.

[EX Q]: Question: What class of ship was the German surface vessel seen? Passage:They flew a mission to the Lofoten Islands on 9 July 1944, searching the coastal shipping lanes and photographing the mainland town of Bodø. Bad weather in northern Scotland on their return prevented a landing, and they finally landed at RAF Leuchars with just 10 gallons left in the fuel tanks. On 12 July, they again flew, via a refuelling stop at RAF Sumburgh in the Shetland Islands, to the Lofoten Islands, and then on to Altenfjord, to search for German surface vessels, flying 750 miles to the Norwegian coast above thick cloud. The top cover of their aeroplane blew off as they descended towards the fjord to make their photography run, subjecting the crew to freezing temperatures for the remainder of the flight. They made a photographic run over the targets they found, including the Tirpitz. They lost their codebooks through the open hatch, so were unable to obtain radio assistance on the way back. They flew 2,300 miles in a mission that lasted nearly 8 hours, landing at RAF Wick, but were immediately refuelled and sent on to Leuchars for the photographs to be developed. The intelligence brought by these missions were of crucial importance: Flight Lieutenant (later Air Vice Marshal) Dodd was awarded an immediate Distinguished Service Order and Flight Sergeant Hill an immediate Distinguished Flying Medal. The citations were gazetted on 8 September and read:
