What distinguishes Paco in the history of Manila arrabales?

The choice stating that Paco is distinguished in the history of Manila arrabales because it was the first town built around a train station is correct because Paco played a pivotal role in the expansion of urban infrastructure in Manila during the late 19th and early 20th centuries. The establishment of the railway significantly influenced the development of the area, as the train station became a central point for transportation, fostering both residential and commercial growth.

This railway hub allowed for the movement of people and goods, which in turn catalyzed economic activities in Paco. It marked a shift in how the urban landscape was organized and reflected the broader trends of modernization and industrialization occurring in urban areas at that time. As a result, Paco's identity was closely intertwined with its function as a transit-oriented development, setting a precedent for other areas in Manila's expansion as transportation infrastructure facilitated urban growth.

In contrast, the other choices do not accurately capture the key distinguishing factor of Paco. Building around a trading port, specialized commercial streets, or serving as a summer resort might describe other neighborhoods or towns in Manila but do not pinpoint the unique significance of Paco's connection to the railway station to the city's historical development.
