Wait, but sometimes there aren't three synonyms for a proper noun. "Gerd Keiser" can't really be replaced with three different names. Maybe the user made a mistake here. I'll have to see. Let me look at the initial instruction again: "alter every word with 3 variants as word1." So regardless of whether the word is a proper noun or not, they want three variations for each word. But that's not feasible for names. Alternatively, maybe the user intended to remove the brand and names first, then alter the remaining words. The first line of the query says "Skip brands and names." So probably, I should first remove any brands and names, then replace each word with three synonyms.

For "Ppt", the example uses Deck, so acronyms can be replaced with their full forms or synonyms. Numbers and editions might need specific handling.

Let me process each line carefully, ensuring that I don't miss any words. Also, the user might be aiming for an educational resource, so the variants should be appropriate for academic contexts. For example, "supplement" could be "adjunct|addition|complement". "Comprehensive" could be "thorough|complete|exhaustive".

But "5th" is a numeral, so synonyms might not be available. Maybe the user expects to keep the numeral as is and focus on the word "Edition". For "Ppt", since it's an acronym, replacing it withPresentationor similar.
