Which theme is best supported by the comparison in this passage from My Antonia? The daughters of Black Hawk merchants had a confident, unenquiring belief that they were “refined,” and that the country girls, who “worked out,” were not. The American farmers in our county were quite as hard-pressed as their neighbours from other countries. All alike had come to Nebraska with little capital and no knowledge of the soil they must subdue. All had borrowed money on their land. But no matter in what straits the Pennsylvanian or Virginian found himself, he would not let his daughters go out into service. Unless his girls could teach a country school, they sat at home in poverty. The Bohemian and Scandinavian girls could not get positions as teachers, because they had had no opportunity to learn the language. Determined to help in the struggle to clear the homestead from debt, they had no alternative but to go into service. Some of them, after they came to town, remained as serious and as discreet in behaviour as they had been when they ploughed and herded on their father’s farm. Others, like the three Bohemian Marys, tried to make up for the years of youth they had lost. But every one of them did what she had set out to do, and sent home those hard-earned dollars. The girls I knew were always helping to pay for ploughs and reapers, brood-sows, or steers to fatten. Life on the prairie builds strong, healthy people. America is a country built on business. Having a clear goal to help family leads people to succeed. A good father protects his daughters.
