A) A = hot, dry with a high ratio of CO₂ to O₂; B = cool, moist with a low ratio of CO₂ to O₂
B) A = hot, dry with a low ratio of CO₂ to O₂; B = cool, moist with a high ratio of CO₂ to O₂
C) A = cool, moist with a high ratio of CO₂ to O₂; B = hot, dry with a low ratio of CO₂ to O₂
D) A = cool, moist with a low ratio of CO₂ to O₂; B = hot, dry with a high ratio of CO₂ to O₂
E) A = hot, dry with a high ratio of CO₂ to O₂; B = cool, moist with a high ratio of CO₂ to O₂
