参考答案
正确答案：D
解析： The professor mainly discusses the effects of mail-order catalogs on rural America. The professor says Farm families were isolated, often with limited funds, and few could afford the time or the expense of shopping in the city. But all of this changed with the introduction of the mail-order catalog; The Sears catalog sold food, clothing, machinery, tools, stoves-anything and everything a farm family might need. (2.1)
