Question

Oft did the harvest to their sickle yield,

Answer 1

A. The details about farming are rooted in the period, while the theme that hard work brings satisfaction can be applied to any period.

There are tools mentioned in the poem, for example a sickle (a blade used for cutting down crops) and a team of oxen to pull the plow, that are not often used today since more modern technology has made farming easier. The idea that if you work hard you'll feel good about what you've achieved still holds true today though!
