Suppose Alex Honnold (born August 17, 1985) is an American rock climber best known for his free solo ascents of big walls. He is the first and only climber to free solo Yosemite's El Capitan. Honnold has been the subject of numerous films and documentaries, including the Academy Award-winning documentary Free Solo.
Can we infer that "Alex Honnold has never used any climbing equipment in his climbs."? Yes, no, or maybe?
