Answer:
The free-verse form helps the following theme:
B. the theme that happiness cannot be defined but needs to be experienced.
Step-by-step explanation:
A poem written in free verse presents lines that do not rhyme. It has no regular rhythm, and no metric pattern is observed. Therefore, the poem's structure is irregular on the one hand, but freer on the other. In the case of the poem "Happiness" by Carl Sandburg, the free-verse form helps convey the idea that happiness has no definition, no recipe. Happiness itself is too irregular to be contained in a structured poem. It is something that can only be felt, experienced, not something that can be put into words, classified, molded, organized. The form of the poem is, therefore, a reflection of happiness.
