Although large cities are generally more polluted than the countryside, increasing urbanization may actually reduce the total amount of pollution generated nationwide. Residents of large cities usually rely more on mass transportation and live in smaller, more energy-efficient dwellings than do people in rural areas. Thus, a given number of people will produce less pollution if concentrated in a large city than if dispersed among many small towns.

Summarize Argument
The author’s main conclusion is that increasing urbanization might reduce the total amount of pollution in the nation. This is because people in more urban areas tend to rely more on mass transit and live in more energy-efficient houses than people in more rural areas. The same number of people in an urban area will produce less pollution than the same number of people in a rural area.

The author concedes that large cities are generally more polluted than the countryside. This is not called into question by the author.
C
It is a statement serving merely to introduce the topic to be addressed in the argument and plays no logical role.
The referenced text is the conclusion.
D
It is a premise offered in support of the conclusion that large cities are generally more polluted than the countryside.
The referenced text is the conclusion. The claim that large cities are more polluted than the countryside is a concession.
E

This accurately describes the role of the referenced text. It’s a conclusion supported by the claim that a given number of people will produce less pollution if concentrated in a large city than if dispersed among many small towns.
