Which action by Yasuko Namba nearly caused Beidleman's death?

• A. She tried to step forward while he was still stringing the ropes
• B. She shouted to the crew during rope setup
• C. She removed his safety rope
• D. She pulled on his rope to test tension

Answer: (A)

In rope fixing on a high-altitude climb, staying still during the setup is essential because the person stringing the ropes is actively working from an edge and is connected to anchors. Any forward movement can yank or destabilize the line, shift weight, or cause the person coordinating the setup to lose balance. When Yasuko Namba stepped forward while Beidleman was still stringing the ropes, that motion disrupted the delicate setup and exposed Beidleman to a sudden loss of balance, nearly sending him to his death. Other actions—shouting during the setup, removing a safety rope, or pulling on a rope to test tension—introduce danger in different ways, but they don’t describe the same immediate, balance-disrupting moment that directly endangered Beidleman during the rope installation.
