Question

complete the rhyme scheme.
a a a b b
two roads diverged in a yellow wood,
and sorry i could not travel both
and be one traveler, long i stood
and looked down one as far as i could
to where it bent in the undergrowth;

Explanation:

Rhyme scheme is determined by the ending sounds of lines. The first line ends with "wood", the second with "both", the third with "stood". "Wood", "both", and "stood" have the same vowel - like sound (though "wood" and "stood" are not perfect rhymes in modern pronunciation, in traditional poetic analysis, they are often considered for rhyme scheme purposes here). So the first three lines are assigned the same letter "A". The fourth line ends with "could" and the fifth with "undergrowth". "Could" and "undergrowth" have a different ending sound from the first three lines, so they are assigned "B".

Answer:

A, A, A, B, B
