Q: 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 Michał 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 Żurawno, by 100,000 men under Ibrahim Pasha, a new peace treaty was signed, the Treaty of Żurawno.: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.

Q: Passage: On 11 February 1727 Spain, under command of the Marquis de las Torres and supervision of Chief Engineer of the Spanish Royal Engineer Corps Marquis of Verboom, laid siege to the city . Depending on the sources, Spanish troops were between 12,000 and 25,000. British defenders were 1,500 at the beginning of the siege, increasing up to about 5,000 by troops brought from overseas by a fleet commanded by Charles Wager. After a four-month siege, with several unsuccessful and costly attempts, Spanish troops gave up and retired on 12 June. Spain had lost over 1,400 men while the British had suffered around 300 casualties. The Spanish had expected material help from the Austrians promised under the Treaty of Vienna, but they received little. They had been outmanoeuvred by British diplomats, who had concluded a secret deal with the Austrians to prevent them intervening.

Q: Passage: Over the centuries, Weimar remained a small town of less than 5,000 inhabitants. When it became the capital of Saxe-Weimar in 1572, population growth was stimulated and population increased from 3,000 in 1650 to 6,000 in 1750. Around the year 1800, Weimar had 7,000 inhabitants. Their number grew constantly over the years to 13,000 in 1850, 28,000 in 1900 and 35,000 at the beginning of World War I. During the interwar period, the new capital of Thuringia saw a population boom, which led to 65,000 inhabitants in 1940. Since that time, the population levels have stagnated. The years 2009 to 2012 brought a moderate growth of approximately 0.35% p. a., whereas the population in bordering rural regions is shrinking with accelerating tendency. Suburbanization played only a small role in Weimar. It occurred after the reunification for a short time in the 1990s, but most of the suburban areas were situated within the administrative city borders.
Question: Between 1750 and 1900, how many residents did Weimar gain?

A:
