Wait, the original has "A Comprehensive Guide", so "A" is an article. Should that be spinned? The user said "switch all words with 3 alternatives", so even articles? Maybe, but the example in the query shows "Switch all words with 3 alternatives as spintax w2". So if the user is following that, then every word except the names should be replaced. However, articles, prepositions, function words might not need substitution. The example given by the user in their query may vary. Let me check the user's example again.

"8th edition" is part of the title's edition, but the title itself is the proper noun. Wait, the full title might be "Microelectronic Circuits, 8th Edition," but in the original text, it's written as

I should also verify if words like "field" in the first sentence should be replaced. "Field" in "those working in the field" might be rephrased as "sector | domain | area".
