Example Input: Passage: Spindler was born in odz, Poland, to an ethnic German family. He was the son of Gertrud Alma (nee Bernewitz) and Oskar Karl Spindler; his father was a businessman. Spindler was considered part of the Volksdeutsche by the Nazi regime, and after the German invasion of Poland in 1939 was required to join the Deutsches Jungvolk (part of the Hitler Youth). When Germany's Eastern Front collapsed in 1944, Spindler and other children of odz were evacuated to a rural estate north of the city. In January 1945, he and his companions were forced to flee west on foot to escape the advancing Red Army; many of them were killed by starvation, exposure, or bombing raids. Spindler was eventually reunited with his family in Magdeburg, and they settled in Weienfels, Saxony-Anhalt, which became part of the Soviet occupation zone and later East Germany. He was blacklisted from attending university due to his anti-Soviet views, and at the age of 17 was granted permission to move to Australia, sponsored by a relative who had settled in Melbourne.
Link Information: By 1940, it had eight million members.
Answer: eight million
Example Output: How many children were part of the Hitler Youth the year the German Eastern Front collapsed?

Example Input: Passage: The follow-up, Waterpistol, was recorded in 1991 at London's Star Street Studio and Chapel Studios, Lincolnshire. Shortly after the recording of Waterpistol was complete, the Star Street studio burnt down and most of the tapes were destroyed. The only remaining DAT of the album was in the possession of producer Chris Allison. At the time, Allison was in Los Angeles, and when he returned, it transpired that he had left the copy in his hire car. It was only found weeks later after a frenzied search. However, by this point, Ghetto had folded so the record was without a distributor. Shack split, with Wilkinson joining fellow Liverpudlian John Power (formerly of The La's) to form the successful Britpop band Cast. The Head brothers accompanied Love for a few touring dates in 1992.
Link Information: none Answer: none
Example Output: How many albums did John Power have writing credit on the year Waterpistol was recorded?
