Question: Passage: The War of the Limburg Succession, was a series of conflicts between 1283 and 1289 for the succession in the Duchy of Limburg. The cause of the War of the Limburg Succession was the death of Waleran IV, Duke of Limburg in 1280, and his only daughter Ermengarde of Limburg in 1283. Waleran IV had no sons and Ermengarde had no children. Ermergarde had married Reginald I of Guelders, who now claimed the Duchy of Limburg. However, Waleran's nephew Adolf VIII of Berg, son of his elder brother Adolf VII of Berg, also claimed the Duchy. Unable to assert his claims, he sold them in 1283 to the mighty John I, Duke of Brabant. Between 1283 and 1288, several smaller confrontations occurred between both sides, none of them decisive. Meanwhile, most of the other local powers chose sides. Siegfried II of Westerburg, the Archishop of Cologne and ruler of the Electorate of Cologne, traditional enemy of the Duke of Brabant, forged an alliance with Reginald I, joined by Henry VI, Count of Luxembourg, and his brother Waleran I of Luxembourg, Lord of Ligny, as well as by Adolf, King of Germany. On the other side the Counts of Mark took the chance to affirm their independence from the Archbishop of Cologne and together with the Counts of Loon, Tecklenburg, and Waldeck allied with Brabant and Berg. The citizens of the City of Cologne, eager to emancipate themselves from the Archbishop's rule, also joined this alliance. After the decisive Battle of Worringen in 1288, won by Duke John I of Brabant and his allies, the Duchy of Limburg came in the possession of the Duke of Brabant. The City of Cologne gained its independence from the Archbishopric and finally the status of an Imperial city in 1475.
Question: How many people did Duke of Brabant forge an alliance with?

Answer: number


Question: Passage: The Steelers opened up their regular season on the road against their old AFC North division rivals, the Baltimore Ravens. The Ravens scored quickly on their first drive, when only three plays into the game, Baltimore wide receiver Anquan Boldin caught a 27-yard touchdown pass from quarterback Joe Flacco. The Ravens scored again on the ensuing drive when running back Ray Rice ran in a 1-yard touchdown, putting Baltimore on top 14-0 early in the first quarter. The Steelers battled back on the next drive, driving down to the Ravens 11-yard line. Pittsburgh scored on a third-and-goal play when wide receiver Emmanuel Sanders caught a touchdown in the back of the end zone from quarterback Ben Roethlisberger. The Ravens responded by scoring again, this time on an 11-yard pass from Flacco to Rice. At halftime the Ravens led 21-7, just like in the 2010 playoffs. But unlike that game, the Ravens did not let up their dominance in the second half. On Pittsburgh's first play from scrimmage in the second quarter, Ravens defensive lineman Haloti Ngata stripped Roethlisberger of the football and recovered it at the Steelers 18-yard line. The Ravens scored yet again when tight end Ed Dickson caught an 18-yard touchdown pass from Joe Flacco. A two-point conversion by punter/holder Sam Koch put the Ravens on top 29-7. The Ravens never looked back, and put up two more Billy Cundiff field goals to close out the game 35-7. The Steelers finished with 7 turnovers in the game. The loss marked the Steelers first opening day loss in 8 years, and left Pittsburgh at the bottom of the division with an 0-1 record.
Question: How many games did the Steelers win this season??

Answer: number


Question: Passage: In 1989, the 1989 Detroit Tigers season collapsed to a 59–103 record, worst in the majors. The franchise then attempted to rebuild using a power-hitting approach, with sluggers Cecil Fielder, Rob Deer and Mickey Tettleton joining Trammell and Whitaker in the lineup (fitting for the team with the most 200+ home run seasons in baseball history). In 1990, Fielder led the American League with 51 home runs (becoming the first player to hit 50 since George Foster (baseball) in 1977, and the first AL player since Roger Maris and Mickey Mantle in 1961), and finished second in the voting for AL MVP. He hit 44 home runs and collected 132 RBI in 1991, again finishing second in the AL MVP balloting. Behind the hitting of Fielder and others, the Tigers improved by 20 wins in 1990 (79-83), and posted a winning record in 1991 (84–78). However, the team lacked quality pitching, despite Bill Gullicksons 20 wins in 1991, and its core of key players began to age, setting the franchise up for decline. Their minor league system was largely barren of talent as well, producing only a few everyday players during the 1990s. Adding insult to injury, the Tigers and radio station WJR announced in December 1990, that they were not renewing the contract of long-time Hall of Fame play-by play announcer Ernie Harwell, and that the 1991 season would be Harwells last with the team. The announcement was met with resounding protests from fans, both in Michigan and around the baseball world.
Question: What was Ernie Harwell final season announcing for radio station WJR?

Answer:
date
