In this case, "Google Books" is a name, so it remains. The other words like "Algunos", "de", "los", etc., are replaced. So in the spintax version, each of these words is replaced with three synonyms. Then, the next sentence: "Conclusión Los libros de Carlos Annacondia son..." The Conclusión is not a name, so "Conclusión" is replaced with synonyms like Resumen, etc. The rest of the words are replaced similarly.

I should be careful with verbs. "Ha sido" becomes "ha ejercido", "ha actuado", "ha fungido". "Ha fundado" could be "ha creado", "ha establecido", "ha iniciado".

Some tricky parts might be phrases where the options might change the meaning if not careful. So, it's important to find synonyms that fit the context. For example, "extensivamente" (extensively) could be abarcador.

Wait, but some words might not have three synonyms, or the user expects different ones. Let me verify each synonym for accuracy. For example, "estilo claro" becomes "estilo|manera|forma" and "accesible|fácil de entender|sencillo". That makes sense.
