answer:Given the implementation shared and the resulting recursive issues specifically within the `add_to_plus_expr/2` predicate during inversion (reversing from a `+` expression to an `add` expression), the key focus should be crafting a balanced approach that can efficiently perform in both directions—direct and inverse. The provided `add_to_plus_expr/2` fails on inverse transformation due to not accounting for Prolog's interpretation of `+` expressions as built-in arithmetic operations rather than structures that can be decomposed like compound terms. Prolog does not inherently allow the decomposition of arithmetic expressions like `2 + 3` into its constituent parts in the same way it allows for compound terms created with user-defined functors. However, based on your implementation, a direct adjustment to handle the reverse mapping is not straightforward because built-in arithmetic expressions are not directly pattern-matched in the same way compound terms are. Additionally, the assignment specifically restricts direct recursion or use of built-ins for the last task, hampering the straightforward application of recursion that could resolve the functional inversion problem for arithmetic expressions. Considering these constraints, a workaround that employs the discussed approach outside of the specific restricted context or offers a generalized solution that bypasses the direct restriction is challenging. Hence, focusing on the already provided tasks, let's ensure the fundamental operation works well in the forward direction. For the reverse transformation (going from `+` expression to `add` expression), it involves interpretive capabilities beyond straightforward pattern-matching due to Prolog's treatment of arithmetic expressions. Here’s an illustrated correction focusing on direct transformations, ensuring that forward operations with `add_to_plus_expr` and `named_to_op_expr` are properly defined, as these parts of the system are within the user's control and their behavior is well-defined in your description: Given the complexity introduced by transforming standard arithmetic expressions backward without direct manipulation (as Prolog sees `2 + 3` as an arithmetic operation to be evaluated rather than a structure), and the explicit prohibitions, the correct forward approach for converting an `add` structure to a `+` expression in Prolog could stay as originally designed: ```prolog add_to_plus_expr(Expr, Expr) :- integer(Expr). add_to_plus_expr(add(X, Y), PlusExpr) :- add_to_plus_expr(X, XExpr), add_to_plus_expr(Y, YExpr), PlusExpr =.. [+, XExpr, YExpr]. ``` The inverse operation would ideally involve pattern-matching against the `+` operation structure, but given Prolog’s execution model and its handling of arithmetic as direct evaluation rather than term manipulation, this cannot be done in a straightforward manner without breaching the task's stated restrictions. Instead, for the forward transformations (like `add` -> `+` and `named operation` -> `operation symbol`), ensuring they are correctly handled as per the above example keeps alignment with Prolog's capabilities and task constraints. Completing all illustrative procedures provided requires careful adherence to Prolog's execution and evaluation model, especially when interpreting explicit arithmetic expressions versus manipulating symbolic representations. Due to these nuanced restrictions, directly provided code for the inverse case would step outside the plausible Prolog pattern-matching and execution constraints as expressed in the assignment.

answer:I'm unable to create visual content such as coloring text or recording videos. However, I can still write a short story for a Cartoon Network Show, designed as a romantic comedy, with a focus on using a variety of vowel sounds. Here's the story: --- In the magical town of Euphoria, Elena, a zany, electric-blue elephant, had eyes only for Oliver, an orange octopus with an outstanding sense of humor. Every day, under an enormous elm tree, they'd exchange jokes, laughter echoing into the ether. "Aha!" exclaimed Elena, her big ears flapping with excitement. "How about we embark on an adventure to the Enchanted Ice Cream Isle tomorrow?" Oliver's eight arms wiggled with joy, as he found Elena's enthusiasm utterly infectious. The next day, amidst azure skies and a blazing sun, their journey began. They traversed through treacherous terrains, overcame obstacles with optimism, and their laughter was a constant companion, as melodious as a musical note. As twilight tinged the sky with hues of pink and purple, they arrived at their destination. Before them lay an ice cream parlor, its neon sign flickering with promise. Inside, they discovered an array of flavors, colors blending beautifully in the frosty air. Sharing a gigantic, glistening sundae, their eyes met, sparkling with shared delight. Under the glow of a neon sign, Oliver tentatively extended a tentacle. Elena, feeling a flutter in her heart, interlocked her trunk with it. In that moment, surrounded by ice cream magic, an unspoken bond was formed. Their journey back was under a velvet night sky, stars winking at their newfound connection. In Euphoria, love brewed not just in grand gestures, but in shared adventures and boundless laughter. And so, Elena and Oliver's love story began, as sweet and enduring as the ice cream from that enchanted night. --- I hope you enjoyed this story and can imagine the variety of vowel sounds used!

answer:The expression "pero nada más alejado de la verdad" can be translated into English as "but nothing could be further from the truth."
