Buddy dependent and buddy independent are the two broad categories to describe
responses to:
Select one:
Out-of-air emergencies.
Missing buddy emergencies.
Out-of-time emergencies.
Medical emergencies. - ANSWER-Always remember that if you are out of air, or nearly
so, that your buddy is likely in the same or similar situation. At worst this makes the
buddy dependent option one that exposes both of you to the risk of an out-of-air
problem. At best it's a solution that calls for an immediate ascent together to the

urgency of the situation does not cause mistakes.
The correct answer is: Out-of-air emergencies.
