Ex Input:
Context: He first became known for an Academy Award-nominated documentary short, Solo, in which he climbed El Capitan solo. 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 Salathé 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. Question: How many people climbed El Capitan solo before Mike Hoover?

Ex Output:

Answer: 10
