OE

Because the description of “short, declarative sentences” matches up with the word spare in the first part of the sentence, you need something in the blank that matches up with “flowery,” meaning full of elaborate literary words or phrases. “Boring” is judgmental, and “floral” just means “of flowers.” Both “classical” and “fictional” might work, but the sentence does not provide clues to suggest the meaning of either. “Baroque,” meaning highly ornate and extravagant in style, fits the sentence.
