Input: Consider Input: Passage: Whale was born into a large family in Dudley, Worcestershire. He discovered his artistic talent early on and studied art. With the outbreak of World War I he enlisted in the British Army and became an officer. He was captured by the Germans and during his time as a prisoner of war he realized he was interested in drama. Following his release at the end of the war he became an actor, set designer and director. His success directing the 1928 play Journey's End led to his move to the US, first to direct the play on Broadway and then to Hollywood, California, to direct films. He lived in Hollywood for the rest of his life, most of that time with his longtime companion, producer David Lewis. Apart from Journey's End (1930), which was released by Tiffany Films, and Hell's Angels (1930), released by United Artists, he directed a dozen films for Universal Pictures between 1931 and 1937, developing a style characterized by the influence of German Expressionism and a highly mobile camera.

Input: Consider 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

Output: How many children were part of the Hitler Youth the year the German Eastern Front collapsed?

Input: Consider Input: Passage: Mike Hoover is an American mountaineer, rock climber and cinematographer. He first became known for an Academy Award-nominated documentary short, Solo, in which he climbed El Capitan solo. His first major involvement in commercial film was with The Eiger Sanction (1975), in which he taught Clint Eastwood how to climb in the Yosemite valley before the film was shot in Grindelwald, Switzerland in 1974. Hoover has since been a cinematographer for the documentaries To the Ends of the Earth (1983), To the Limit (1989), The Endless Summer 2 (1994) and Zion Canyon: Treasure of the Gods. In the late 1980s, he made 18 trips to Afghanistan to shoot war footage that was later featured in a program named The Battle for Afghanistan (1987). Hoover has led various film teams all over the world, particularly in physically and politically difficult locations, such as Everest, K2, the precarious rock faces of the Eiger and the Venezuelan jungle.
Link Information: After his successful solo ascent of the Leaning Tower, Royal Robbins turned his attention to the Yvon Chouinard-T.M. Herbert Muir Wall route, completing the first solo ascent of El Capitan during a 10-day push in 1968. The first solo ascents of El Capitan's four classic "siege" routes were accomplished by Thomas Bauman on The Nose in 1969; Peter Hann on the Salathe Wall in 1972; Robert Kayen on the Layton Kor-Steve Roper West Buttress route in 1982; and Beverly Johnson on the Cooper-Baldwin-Denny Dihedral Wall route in 1978. Other noteworthy early solo ascents were the solo first ascent of Cosmos by Jim Dunn in 1972, Zodiac by Charlie Porter in 1972; Tangerine Trip by David Mittel in 1985; and The Pacific Ocean Wall by Robert Slater in 1982. These ascents were long 7- to 14-day ordeals that required the solo climber lead each pitch, and then rappel, clean the climbing gear, reascend the lead rope, and haul equipment, food, and water using a second haul rope. Answer: 10
Output: How many people climbed El Capitan solo before Mike Hoover?
