[EX Q]: Question: How old was the Duke of Saxony when he appointed Adolf I to hold Holstein and Stormarn? Passage:He was appointed to hold as fiefs Holstein and Stormarn, including Hamburg, by Lothair, Duke of Saxony, in 1111. By this appointment Adolf became the leader of the defence of Germany against the Wagri. Allied with Henry, the prince of the Obotrites, he repeatedly waged war on Wagria and the Rugians. After Henry's death (1127), Adolf remained allied with his sons Canute and Sventepolk, but they were soon dead and Lothair, by then King of Germany, had made Canute Lavard, a Danish prince, Duke of Schleswig. Feeling his authority threatened by the Danish upstart, Adolf attacked his castle of Albergs, captured the garrison, and destroyed its defences. He left his counties intact to his second son, Adolf II, since his eldest, Hartung, had been killed in the Second Battle of Chlumec in 1126.

[EX Q]: Question: In what year did Sean Rash roll a perfect game in the Tournament of Champions? Passage:The PBA Tournament of Champions is one of the four major PBA (Professional Bowlers Association) bowling events. The inaugural event, held by the PBA in , featured all 25 PBA Tour title-holders to date, and was won by PBA Hall of Famer Joe Joseph, who had qualified for the tournament only four events prior. In , the tournament featured all champions since the 1962 event, before officially becoming an annual event in 1966 (at that time featuring the most recent 48 tour champions). From 1965 to 1993, Firestone Tire sponsored the Tournament of Champions. From 1965 until 1994, the tournament was contested at Riviera Lanes (now AMF Riviera Lanes) in Fairlawn, Ohio near the long-time Firestone World Headquarters in Akron, Ohio. In a notable opening match at the 1967 Tournament of Champions finals, Jack Biondolillo rolled the first-ever nationally televised 300 game. Oddly, Biondolillo would only tally a 188 score in his next match (a victory), before being eliminated in his third match with a 172 score. Biondolillo's feat was not matched until , when Sean Rash rolled the TOC's second televised perfect game in the second match of the stepladder finals. The tournament has also seen a pair of televised 299 games, by Don Johnson () and Mika Koivuniemi (). The 2011 event also featured the lowest-ever game bowled in a nationally televised PBA event as well as the largest pin differential in a PBA match, when Koivuniemi defeated Tom Daugherty in the semifinals, 299–100.
