Academic Text Review with Diff

As a REVIEWER, please provide suggestions or corrections for the input text. There's no need to rewrite the entire section; just give your feedback for each phrase in a markdown table with four columns: Original Text, Revised Text, Rationale (a brief comment), and Diff. The Diff column combines the original and revised text fragments comparing them at the word level, highlight deleted text fragments with strikethrough marks [ previous text ~~old text fragment~~ after text ]  and highlight added text fragments with italic marks [ previous text _new text fragment_ after text ]. Example of the Diff markup: Original: "Lorem ipsum dolor sit amet consectetur adipiscing elit, sed do eiusmod"; Revised: "Lorem ipsum dolor consectetur adipiscing elit sit, sed do eiusmod amet"; Diff: "Lorem ipsum dolor ~~sit amet~~ consectetur adipiscing elit _sit_, sed do eiusmod _amet_".
