Input: Consider Input: Passage: The Mataram conquest of Surabaya or Mataram-Surabaya War was a military campaign by the Sultanate of Mataram in the early 17th century that resulted in the capture of the Duchy of Surabaya  and its allies in eastern Java, in modern-day Indonesia. Prior to this conquest, Mataram and Surabaya were rivals for power in central and eastern Java. The campaign began in 1614 when Mataram, under the leadership of Sultan Agung, attacked Surabaya's allies, including Wirasaba. Surabaya and its allies launched a counterattack but were defeated near Pajang in 1616. Over the next few years, Mataram gradually conquered members of the Surabayan alliance, and by 1620, the city of Surabaya itself was under siege, holding out until it surrendered in 1625. With this conquest, Mataram unified most of central and eastern Java under its control, and cemented its position as the dominant power in Java. Surabaya and other conquered areas would remain in Mataram's hands until it was ceded to the Dutch East India Company in 1743. 
Question: How many years from the beginning of Mataram's campaign did it take for the city of Surabaya to surrender? 
Answer type: Number 

Output: 11.


Input: Consider Input: Passage: Fiorentina purchased Baggio in 1985 for £1.5 million. During his time at the club, despite initial injuries, he became extremely popular, and is regarded as one of the clubs best ever players. In his 1985–86 Serie A with the club, Fiorentina finished in fifth place in Serie A and reached the semi-finals of the 1985–86 Coppa Italia, with Baggio making his club debut in the competition. He made his Serie A debut on 21 September 1986 against U.C. Sampdoria, and he also made his European debut that season on 17 September 1986, in an 1986–87 UEFA Cup match against Boavista F.C.. Baggio suffered another knee injury on 28 September, and he was operated again, requiring 220 stitches to have it rebuilt, losing 12 kg as a result and missing most of the 1986–87 Serie A. Baggio returned, and scored his first league goal from a free-kick on 10 May 1987 in a 1–1 draw against Diego Maradonas S.S.C. Napoli, the eventual Serie A champions; Baggios equaliser saved Fiorentina from relegation. 
Question: How many days before Baggio made his Serie A debut did he make his European debut?
