I'll mark brainliest xD Reread the passage about the mill girls, and then answer the question.

What did the doffers do?

A. repair broken spinning frames

B. replace empty bobbins with full ones

C. change out full bobbins for empty ones

The paragraph:

“The early mill-girls were of different ages. Some were not over ten years old; a few were in middle life, but the majority were between the ages of sixteen and twenty-five. The very young girls were called "doffers." They "doffed," or took off, the full bobbins from the spinning-frames, and replaced them with empty ones.”
