Final answer:
The sentence is rewritten with academic diction, focusing on the lesson that one should prioritize inner beauty over outer appearances, as exemplified by Belle and the Beast's story.
Step-by-step explanation:
Rewriting the sentence while employing academic diction yields the following: The narrative of Beauty and the Beast is widely known, and while absorbing its teachings is relatively simple, integrating these lessons into daily existence proves more challenging. The narrative's essence suggests that one's inner beauty ought to be the primary focus upon engaging with others. Despite the Beast's formidable and off-putting exterior, responsible for his lack of popularity, Belle manages to look beyond his outward form, consequently developing affection for his internal qualities.
