Passage: Over the next year, however, the Polish forces were subject to attrition, as the Sejm again refused to raise taxes and pay the army, resulting in mass desertions of unpaid soldiery. The Polish problems were further aggravated by the incompetent leadership of hetman Micha Kazimierz Pac, who obstructed Sobieski's leadership, while the Ottomans continued to receive reinforcements. Nonetheless in 1674 the Commonwealth resumed the offensive, taking advantage of a new Muscovy-Ottoman conflict that year, and the Polish-Ottoman war remained undecided.:275 Sobieski's force of 6,000 defeated 20,000 Turks and Tatars under Ibrahim Shyshman in the battle of Lwow in August 1675.:653 Even after the Battle of Trembowla, the Sejm still refused his pleas for more funds and a larger army.:653 In 1676, after Sobieski's 16,000 withstood the two-week siege of Zurawno, by 100,000 men under Ibrahim Pasha, a new peace treaty was signed, the Treaty of Zurawno.:655 The peace treaty partially reversing those from Buczacz: the Ottomans kept approximately two thirds of the territories they gained in 1672, and the Commonwealth no longer was obliged to pay any kind of tribute to the Empire; a large number of Polish prisoners were released by the Ottomans.

Passage: The war took a heavy toll, especially in the northern British colonies. The losses of Massachusetts men alone in 1745-46 have been estimated as 8% of that colony's adult male population. According to the Treaty of Aix-la-Chapelle, Louisbourg was returned to France three years later, in exchange for the city of Madras in India, captured by the French from the British. This decision outraged New Englanders, particularly Massachusetts colonists who had contributed the most to the expedition The British government eventually acknowledged Massachusetts' effort with a payment of 180,000 after the war, which the province used to retire its devalued paper currency. The peace treaty, which restored all colonial borders to their pre-war status, did little to end the lingering enmity between France, Britain, and their respective colonies, nor did it resolve any territorial disputes. Tensions remained in both North America and Europe, and were reignited with the 1754 outbreak of the French and Indian War in North America, which spread to Europe two years later as the Seven Years' War. Between 1749 and 1755 in Acadia and Nova Scotia, the fighting continued in Father Le Loutre's War.
Question: In what year did the Seven Years' War begin in Europe?
answer:

Passage: In 1989, the 1989 Detroit Tigers season collapsed to a 59103 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 (8478). 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
