Answer and Explanation:
According to the passage, young girls had to be on duty for about 14 hours a day, even if they were not actually working all of that time. Even though money was worth more back then, they were still paid very little - only 2 dollars a week. The very young girls, who had some time to spare, needed to rely on the kindness of the overseer to be able to use their free time to go play, to knit, or to read. As we can infer, there was no concern about employing children instead of sending them to school. The girls clearly could not study much if they were on duty throughout the day.
