Which statements best describe urban areas?

Urban areas are characterized by high population density and a concentration of manufacturing and service industries. This is primarily due to the economic focus of cities, which typically offer a variety of job opportunities in sectors such as finance, retail, healthcare, education, and manufacturing. The population density in urban areas leads to the development of infrastructure and services that support both residents and businesses, creating a dynamic environment where people live close to workplaces and various amenities.

In contrast, high agricultural productivity is more typical of rural areas where land can be used extensively for farming. Concerns with rural employment specifically pertain to employment opportunities outside urban settings, indicating a focus away from urban characteristics. Predominantly residential areas describe some aspects of urban neighborhoods, but urban environments are not solely residential; they include commercial and industrial zones that provide diverse economic functions and employment. Therefore, the description of urban areas as having high population density with a focus on manufacturing and services accurately captures the essential characteristics of urbanization.
