The first parameter represents a poem that has no blank lines and has had leading and trailing
whitespace removed. The second parameter represents a poetry form description. And the third

that do not have the right number of syllables for the poetry form description. The lines

The parameter represents a tuple of phonemes. The function is to return a tuple that contains the
last vowel phoneme and any consonant phoneme(s) that follow it in the given tuple of phonemes.
The ordering must be the same as in the given tuple. The empty tuple is to be returned if the tuple
of phonemes does not contain a vowel phoneme.

The first parameter represents a word, as does the second parameter. The third parameter
