Wait no, in the example, "for" is replaced with as? Wait in the example, the first part is "Libertango as-Trumpet: The Thorough Manual concerning Playing Astor Piazzolla’s Iconic Piece." So "for" becomes as, but the example seems to use the original word as one of the options. Maybe the user allows the original word in the options. That's a bit conflicting, but since the user didn't specify excluding the original word, perhaps it's allowed.
