What does the paragraph in the example showcase?

The correct answer indicates that the paragraph being discussed has already been completed and is therefore presented as a finished piece. This implies that the content is finalized, demonstrating a specific point, argument, or narrative that has been conveyed effectively. The use of past tense suggests that the writing is complete and has been formally articulated, allowing readers to engage with it as a finished work rather than a work in progress or a speculative piece.

In contrast, the other options suggest various states of incompleteness or uncertainty regarding the writing process. For instance, stating that it "was not written" implies the absence of any text, while "could be written" suggests potential or possibility rather than certainty. "Is being written" indicates that the paragraph is still in progress, which does not align with the notion that the example showcases something that has already been formally presented.
