Question

how is a poem’s rhyme scheme marked and identified?
○ upper or lowercase letters, such as “abab”
○ roman numerals, such as “ii, ii, ii”
○ arabic numerals, such as “1212”
○ punctuation symbols, such as “?!?!”

Explanation:

To identify a poem's rhyme scheme, we assign a unique letter (starting with A) to the first line's end - sound. Then, for each subsequent line, if it rhymes with a previous line, we use the same letter; if it has a new end - sound, we use the next letter in the alphabet. For example, in a poem with lines that rhyme as line 1 with line 3, and line 2 with line 4, the rhyme scheme is marked as ABAB. Roman numerals are not used for rhyme schemes, Arabic numerals are not the standard way, and punctuation symbols have no role in marking rhyme schemes.

Answer:

A. upper or lowercase letters, such as "ABAB"
