Answer: To compare a physical journey to life
Step-by-step explanation:
Poems have different purposes but I would say that the correct answer is to compare a physical journey to life. This is the theme and motif that is the most common when it comes to poetry. Poets are often describing their journey through life and situations that they were experiencing.
I would also say that the family conflicts are the most common in the period of Realism and compare between human behavior and the exploring nature if the most common in Romanticism.
