Air pollution is accurately described by which statement?

Question

BlackTom AI · Accepted Answer

Consider the question about how air pollution is accurately described. 
Option 1: 'Air pollution occurs when more pollutants are emitted into the atmosphere than can be safely absorbed and diluted by natural processes.' This captures the core idea that pollution results from emissions exceeding the environment's capacity to mitigate them through dispersion, dilution, and natural removal.
Option 2: 'A majority of the people in the United States breathe unsafe air for at least part of the year.' While this statement has elements of concern, it is not a precise definition or description of air pollution itself; it describes exposure patterns rather than the mechanism or characterization of pollution.
Option 3: 'Air pollution is caused by mixing natural water vapor with diesel fuel, creating acid rain.' This misstates the process: acid rain involves pollutants like sulfur dioxide and nitrogen oxides reacting in the atmosphere, not simply water vapor mixing with diesel fuel; it is inaccurate and oversimplified.
Option 4: 'The EPA has identified hundreds of "criteria" pollutants, which are relatively common harmful substances that serve as indicators of overall levels of air pollution.' While true that the EPA identifies criteria pollutants, this option focuses on a definitional detail rather than a direct description of air pollution itself; it also does not fully convey the conditional relationship between emissions and natural processing.
Thus, option 1 provides the most accurate, general description of air pollution by emphasizing the balance (or imbalance) between emissions and the environment’s capacity to absorb or dilute them. The other options either misstate processes, overgeneralize exposure, or introduce peripheral regulatory details that don’t define air pollution itself.
