Hi! If I were you, I would refer to notes given to you by your teacher, as I am not entirely sure what level this is or what your teacher is looking for, or how your teacher may define a theme.
Personally, I would choose:
A theme is a message the text conveys. 
A theme is supported by details in the text. 
A theme is seen over the course of a text.
Again, be sure to double-check with your notes and/or teacher to see how they define it, but in my opinion, I would choose those three!
Hope this helps!

Answer:
It establishes the rhythm of a duet to echo the song.
Explanation:
Parallelism refers to the use of the same grammatical structures in a series of sentences. Most of the time, parallelism is used in order to provide a sense of rhythm to the text. In this case, parallelism provides a sense of rhythm that is meant to echo the song, as it reminds the reader of a duet. As the song is also meant to be a duet (father and mother) the structure of the text highlights the subject matter.
