I should start by going through each sentence and identifying each word. Then, for each word, come up with three suitable synonyms. For example, "solutions" could be "answers|remedies|resolutions". I need to be careful with technical terms like "PDF viewer" to find relevant synonyms. Also, terms like "EPUB" and "MOBI" are specific formats, so they need to stay as they are, but the surrounding words can be rephrased.
Original instruction: "rephrase words in spintax: z. every word with 3 synonyms. Skip brands and names. Text only."
Now, moving to the additional resources section.
But the example given in the user's mind is y, so maybe the user wants each unique word to be converted into a spintax with three synonyms. For example, if the original word is "important", replace it with relevant.
Validate data completeness: Examine the PDF document for degradation or injury employing tools like Adobe Acrobat or internet-based document authentication providers.
"Official website": main site
Also, need to check for correct grammar after substitution. If a word takes a plural form or changes tense, the synonyms should agree. For example, "Use a PDF viewer" becomes "Use a Browser PDF". But perhaps it's better to keep the order as Apply a PDF reader to maintain the structure.
But the example in the original text is something like y, so perhaps each word in the original text that isn't a brand or name is to be replaced with three synonyms. That's a lot. Let me check the original instructions again.
