Which of these best describes the impact of massachusetts' "lowell mills" in the early-to-mid-1800s?   a) women made up a vast majority of their workforce.  b) they were willing to employ runaway southern slaves.  c) women workers were paid the same s their male counterparts.  d) they originated the process of using steam power in factories.

The correct answer is A) Women made up a vast majority of their workforce.

These workers were called the Lowell Mill Girls and at one point in time there was over eight thousand female workers in such factories. This meant that nearly three quarters of the factory staff consisted of females which was a vast majority of workers in the workforce. They weren't paid the same but even the smaller wages helped many get economic independence.
