Why did they say that at Camp Five, 'you were on your own'?

• A. After Camp Five there is little chance of rescue from air or by foot; air is too thin for helicopters; no one can really help the other; 'To each his own'; If you die past this point, your body remains on the mountain.
• B. Rescue helicopters can always reach you at Camp Five.
• C. There is a strong team waiting to retrieve climbers.
• D. The camp has many support teams.

Answer: (A)

The idea being tested is the stark reality of rescue limits at extreme altitudes. Beyond a certain point in the climb, outside help is effectively unavailable because the air is so thin that helicopters can’t operate safely and terrain and weather make coordinated rescues impractical. That pressure and danger mean you must rely on yourself and the people with you, since external rescue isn’t a practical option. The phrase captures a mindset of personal responsibility and self-reliance that climbers face in that zone. The other statements describe rescue possibilities that simply don’t exist there—air support isn’t reliable, there isn’t a ready team to retrieve climbers, and there aren’t abundant support resources waiting at that camp—so they don’t fit the situation.
