SOMEONE HELP PLEASE!! In what ways did the establishment of mill towns in the Northeastern United States rely on earlier economic and technological advancements?

Establishment of mill towns in the northeastern United States relied on economic and technological developments that happened earlier.

The establishment of mill towns in the northeastern United States happened due to the availability and mass production of mills in the country.
IT was the mill that had kicked off the industrial revolution in England and it was as instrumental in the US too.

The advancement of technology by the building of this machine is why the towns could come Into the picture and become industrial powerhouses they eventually became.
