To interpret the theme in a story, a reader should study repeating ideas.
The answer is B. Mrs. Mallard loved her husband, but she is happy that she is free. Back then women were like possessions to their husbands. The wives stayed home to clean the house and take care of the children. When the husband came home the wife was to serve the husband. Wives were no different than maids back then to their husband. Mrs. Mallard did love her husband which is why she was trying to beat it back. However, above all she was free from the "possession of her husband" so she was free. I hope this helps and I hope you understand. Please feel free to ask questions in the comments. Have a nice day!
The Broadway show "Movin' Out" was based on songs written by the songwriter named Billy Joel.
The musical features many of his songs, among which is of course the eponymous song Movin' Out (Anthony's Song), released in 1977 on his album The Stranger. It was an immediate hit, and it influenced many other artistic performances as well.
Refrain is in a song not a poem so C. Refrain.
