Then, when generating new replacements, I need to use common words (not proper nouns) unless the original list contained proper nouns. Wait, but the example shows that Charlie is left as is. So in the input, the user might have proper nouns in a c structure, and we shouldn't touch those. But if they are part of the text, like "Alice went to London," then "Alice" and "London" are proper nouns and should not be altered. every term with 3 variants
But since the user provided an example where the input and output are the same, with existing a parts, maybe the user's actual request is to modify an input text that already contains b parts by replacing each variant within them with other words, possibly generating new sets of three options. Then, when generating new replacements, I need to
