Question

Read this passage from My Antonia.

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.
What difference is implied through the detailed description of the Bohemian Marys and the other girls who worked in town?
Both the Bohemian Marys and the other girls were too busy working to have any fun.
Both the Bohemian Marys and the other girls had a lot of fun once they moved to town.
The Bohemian Marys spent time having fun, unlike the other girls who continued to act seriously.
The Bohemian Marys were more serious than the other girls, who spent a lot of time having fun.

Answer 1

Bohemian because they spent more time than the girls

Answer 2

The difference which is implied through the detailed description of the Bohemian Marys and the other girls who worked in town is the following one:

The Bohemian Marys spent time having fun, unlike the other girls who continued to act seriously.

Check this fragment out: "Others, like the three Bohemian Marys, tried to make up for the years of youth they had lost." That means they tried to compensate for the time they did not spend living as young people are supposed or expected to live: enjoying life, that is, having fun. When they moved to town, all they wanted was to have a blast.

As for the other girls, it is said that, "after they came to town, (they) remained as serious and as discreet in behaviour as they had been when they ploughed and herded on their father’s farm." In other words, they continued to act seriously.
