13 - EASA PPL(A) Theory Exam Questions in English - Why can a pilot become hypoxic at altitude even when breathing faster?

Question 13 - Human Performance and Limitations - EASA PPL(A) - Private Pilot Licence (Aeroplane)

Reduced oxygen partial pressure limits oxygen loading in the lungs; compensation is limited and varies between individuals.

The percentage of oxygen in dry air always falls to zero above 12 000 ft.

Breathing faster automatically restores sea-level oxygen pressure at every altitude.

Hypoxia is caused only by a decrease in the percentage of nitrogen.
