Sawai 21 — Cuentos
Replacement: "In" → Within "the" → an (but "the" is an article; do we replace it? Wait, the user's example didn't include articles, but the instruction says "each word". So if "the" is a word, replace it. But maybe the user considers articles as not to be replaced. Let me check the example provided. In the sample, they replaced "In" with three options, so maybe articles are included. Let me proceed.)
So in the sentence "Sawai 21 Cuentos: A Collection of Timeless Tales", the title is a proper noun, so the replacements would only happen to "A Collection of Timeless Tales" part. However, in the user's example, they have "Sawai 21 Cuentos: A Collection of Timeless Tales" and the output skips "Sawai 21 Cuentos" but replaces the rest. sawai 21 cuentos
