To accurately identify the literary technique employed by the author in "The Song of the Cardinal," I would need specific details or excerpts from the text itself. However, based on the responses provided, here are some insights into each option:
A. Onomatopoeia typically involves words that imitate natural sounds. If the text describes the buzzing of bees in a way that mimics their sound, this would be applicable.
B. Extended metaphor involves a comparison between two unlike things that continues throughout a piece of writing. If the Limberlost is continually compared to other swamplands, this fits the definition.
C. Subtle personification refers to giving human-like qualities to non-human entities. If the frogs in the pond are depicted in a way that reflects their experiences or feelings as if they were human, this would be accurate.
D. Alliteration involves the repetition of the same initial consonant sounds in a series of words. If the sounds of the trees are highlighted through this technique, it would qualify.
If you have specific examples or descriptions from the text, I would be able to help determine which option is the most accurate in describing the literary technique used.
