Final answer:
The workers of Lowell, predominantly daughters of farmers, differed from British workers in that they worked in mills temporarily, as opposed to becoming part of a permanent working class.
Step-by-step explanation:
According to the passage, the workers of Lowell differ from those of Britain because they are daughters of farmers who only work in the factory for a few years. The Lowell system, initiated by the Boston Manufacturing Company, was distinct in its employment of young women, mainly the daughters of Yankee farm families, who came to work in the factories temporarily to earn money for their dowry before returning to their rural communities. This contrasts with the British factory system where the workforce consisted of men, women, and children who often became part of a permanent urban working class due to the Industrial Revolution. Additionally, the Lowell mills offered 'wholesome' activities and tried to maintain the workers' reputations through a chaperone system, which was not a feature of British factory life.
