Which of these best describes the coverage area of SEPTA?

The correct response highlights that SEPTA, or the Southeastern Pennsylvania Transportation Authority, serves the Greater Philadelphia area. This encompasses not just the city of Philadelphia itself but also surrounding suburban regions across several counties, including Bucks, Chester, Delaware, and Montgomery. SEPTA’s mission is to provide public transportation services for both urban and suburban riders, making it a crucial link for commuters traveling into and out of the city.

The other choices are limited in their scope. Focusing solely on the city limits of Philadelphia ignores the extensive suburban network that SEPTA operates. Similarly, claiming that SEPTA only serves suburban regions of Pennsylvania would exclude the core urban service areas within Philadelphia. Finally, stating that SEPTA covers all of Pennsylvania would be inaccurate since its services are concentrated in the southeastern region, and not across the entire state. This understanding of SEPTA's geographic reach is essential for comprehending its operational framework and the communities it serves.
