Answer:
Part A: Joshua Drake allows his children to work in textile factories because of necessity. He states that "necessity compels a man that has children to let them work" and also mentions that he has "no wages, but two days a week at present." These pieces of evidence indicate that Drake allows his children to work out of financial need, as he himself is struggling to make ends meet.
Part B: Joshua Drake feels positively about a law that would limit working hours for children. He believes that such a law would bring him more employment opportunities and improve his own situation. He states that if the hours of labor were limited, it would "bring me into employ" and that he would be willing to accept a decrease in his children's wages if it meant he could earn more. Additionally, Drake believes that limiting the hours of labor would result in more employment opportunities for others as well, stating that it would "find more employment at the machines, and work being more regularly spread abroad, and divided amongst the people at large." These pieces of evidence suggest that Joshua Drake sees the potential benefits of a law that would limit working hours for children.
