Scientific Model. An air-pollution model states that during a temperature inversion, warm air above cooler surface air prevents vertical mixing, trapping pollutants near the ground. Which conclusion follows?
A
A temperature inversion can increase pollutant concentration near the ground.
B
The model says pollutants are trapped only above the warm air layer, within the range and context provided by the passage.
C
Warm air above cool air increases vertical mixing in the model, using the measurements, labels, and constraints given in the prompt.
D
A temperature inversion always removes pollutants from surface air, for the particular investigation and evidence presented here.
