Question

why are temperature inversions particularly problematic in industrial cities? they trap pollutants from industrial activities close to the surface. they cause industrial equipment to malfunction. they improve the dispersion of industrial emissions. they enhance the cooling effects of industrial activities.

Explanation:

Temperature inversions create a layer of warm air over cooler air. In industrial cities, this traps pollutants (like smoke, chemicals) from industrial activities near the surface as the normal upward mixing of air is restricted. Industrial equipment malfunction is not a direct effect. Improving dispersion would be good (but inversions do the opposite). Enhancing cooling effects is not relevant to the problem of inversions in industrial cities.

Answer:

They trap pollutants from industrial activities close to the surface.
