Answer:
The correct answer is "it connects cities that were established on the fall line".
Step-by-step explanation:
Interstate 95 is the main highway that connects cities in the East Coast of the United States. It seems like interstate 95 follows the fall line because it connects cities that were established on the fall line like Richmond, Washington D.C., Trenton, and Hartford. These cities were founded around the fall line because they have great geological characteristics such as: navigable rivers, regions with little elevation to build houses and the presence of rapids and falls to power saw mills.
