How did the industrial revolution contribute to the changing relationship between middle-class husbands and wives? a. the shift from human to steam power in shops and factories left many middle-class husbands unemployed, homebound, and a burden to their wives. b. by the late nineteenth century, most middle-class husbands went to a shop or office to work, thus reducing the prevalence of home-based production, which wives previously supported. c. the employment of middle-class women in noisy, cramped textile factories required husbands to expand their home-based businesses. d. as changing social values gave employed middle-class women greater prestige, middle-class husbands took on more household responsibilities.
