When Messner and Habeler climbed Mount Everest without supplemental oxygen, the scientists had to reevaluate their calculations that VO₂ max at the top of Everest was equal to resting metabolic rate (3.5 ml .kg^-1 . min^-1). They found that the A) barometric pressure was higher than expected at the top of Everest. B) oxygen percentage was higher than expected at the top of Everest. C) air temperature was colder than expected. D) hemoglobin levels increased suddenly at that altitude for those who didn't use supplemental oxygen.

Question
