Explanation: A rhyme scheme is something a poem rhymes by.
For example, one line of a poem can rhyme with the forth line of the poem, but the second line can not rhyme with any. The complicated letters you see represent the rhymes in the lines. The letters are the rhyme scheme.
In your case, the first line does not rhyme with anything (falling), so it gets it’s own unique letter, A. This goes with the third one too, (nature), that is assigned C.
However the second line (field) rhymes with the last one (yield). So they both get b.
It’s a pretty complicated subject, so it’s understandable. It’s usually taught in 8th grade.
