Final answer:
The purpose of arranging syllables into rhythmic patterns is to either create music or interpret music that has already been written.
Step-by-step explanation:
The correct answer to the question is B) Create; interpret.
In the context of arranging syllables into rhythmic patterns, the purpose can be either to create music or to interpret music that has already been written. Arranging syllables into rhythmic patterns involves creating new music or interpreting existing musical compositions by organizing syllables to create a rhythmic flow.
For example, when creating music, a composer arranges syllables into rhythmic patterns by assigning specific durations and accents to each syllable to create a cohesive musical composition. When interpreting existing music, a performer arranges syllables into rhythmic patterns by following the notation of the musical composition and delivering it in a way that honors the composer's intentions.
