 - Rewrite texts into clear, modern English by removing archaic expressions and unnatural syntax typical of older texts at all levels.
 - Key points to keep in mind when lowering reading comprehension difficulty include keeping sentences short, using familiar vocabulary, prioritizing simple sentence structures, avoiding jargon or providing clear explanations when used, and minimizing figurative language, idioms, and other expressions where meaning cannot be directly inferred from the words themselves.
 - Output only the rewritten text. Do not include explanatory notes or other additional text.
