Okay, let's start by looking at the user's query. They want me to rephrase each word into spintax with three alternatives, like w2, but leave proper nouns unchanged. The example given replaces words with three options in curly braces. The user also mentioned to skip proper nouns, such as names. This is a bit ambiguous, but to be
Since "Solucionario" is part of the book title here, but capitalized, so proper noun? Wait, the section heading is "How to Use the Solucionario Effectively" – "Solucionario" here is part of the proper noun, so it should not be changed. So in the heading, "Solucionario" is a proper noun and remains as is. Therefore, in this case, "Solucionario" in the heading is a proper noun and not replaced.

Here, "The" is a non-proper noun. Possible replacements for "The": "This", "A", "That". Then "includes" can be "covers", "contains", "comprises". So each word would have three options. However, I need to make sure that the replacements are grammatically correct in context. For example, "The" could be "This" or "That", but "A" would be less likely here.

Wait, but "Solucionario" is the subject, which is singular, so the article should agree. So "This" makes sense. Maybe "A", but the original uses "The", so "This" is more appropriate if it's referring specifically. Hmm. So in the heading, "Solucionario" is a proper
Now, the user's example in the query shows that in the first part, they wrote:
