Question

Having an above-than-normal gas pressure means we have a (shortage/surplus) of primary air, a high ..................... content, and a low ...................content.

A. Surplus, Oxygen, Carbon Dioxide
B. Shortage, Oxygen, Carbon Dioxide
C. Surplus, Carbon Dioxide, Oxygen
D. Shortage, Carbon Dioxide, Oxygen

Answer 1

Above-normal gas pressure means there is a surplus of primary air, leading to high carbon dioxide and low oxygen content, which aligns with choice C.

Step-by-step explanation:

Having an above-than-normal gas pressure indicates that there is a surplus of primary air.

This would result in a high carbon dioxide content due to excessive combustion or respiratory activity, and a low oxygen content, as more oxygen is being used in the process.

Hence, the correct answer to the question would be: Having an above-than-normal gas pressure means we have a surplus of primary air, a high carbon dioxide content, and a low oxygen content, which corresponds with choice C.

Surplus, Carbon Dioxide, Oxygen.
