Which selection from the excerpt from The Condition of the Working-Class in England in 1844 supports the idea that the creation of the jenny had positive effects?

This invention made it possible to deliver more yarn than heretofore. More weavers were needed, and weavers' wages rose.

By degrees the class of farming weavers wholly disappeared, and was merged in the newly arising class of weavers who lived wholly upon wages, had no property whatever, not even the pretended property of a holding, and so became working-men, proletarians.

Hitherto, so far as this had been possible, yarn had been spun and woven under one roof. Thus began with spinning and weaving that division of labour which has since been so infinitely perfected.
