Final answer:
The unrelated sentence to be deleted is about the incorrect adherence to 'Editing Focus,' which does not match the paragraph's theme of editing for conciseness. Removing this sentence enhances the paragraph's focus and removes irrelevant information not demonstrating the instructed concept of concise writing.
Step-by-step explanation:
The sentence that should be deleted from the paragraph because it is unrelated to the other sentences is: "The text does not adhere to the 'Editing Focus' of this chapter-combining independent clauses in meaningful ways, as discussed in Section 3.6-or employ complex sentence structures."
This sentence does not align with the central theme of editing for more effective sentences within the context provided, which is emphasized on the elimination of unnecessary words, the condensation of wordy phrases, and the overall improvement of sentence construction for clarity and conciseness.
Additionally, the mention of Section 3.6 is incongruent with the rest of the paragraph's content, which does not discuss combining independent clauses or complex sentence structures specifically.
As such, in accordance with the peer review comment, the unrelated sentence should be omitted to improve the paragraph's focus on concise writing and its alignment with the chapter's editing focus. To avoid detracting from the main teaching points about concise language and effective sentence editing, redundant information or examples not directly demonstrating the instructed concept should be removed.
This approach aligns with the practice of streamlining paragraphs to deliver the intended information without unnecessary diversions.
