turned out to be the best part the thief stole the gems from the vault in the bank, and how he did it

Explanation:

The model sentence structure is "I've got... but whether... remains to be seen". We need to arrange the given phrases to match this structure. The phrases are "The thief stole the gems from the vault in the bank" (main action) and "how he did it turned out to be the best part" (the "whether - like" part, adjusted to "how he did it" and the result). Wait, actually, re - examining the model: "I've got the key to my castle in the air, but whether I can unlock the door remains to be seen." So we need a main clause and a "but + whether/how... remains to be seen" clause. Let's arrange the phrases: "The thief stole the gems from the vault in the bank, but how he did it turned out to be the best part." Wait, no, the model has "remains to be seen", but the given phrase is "turned out to be the best part". Maybe a slight adjustment. Let's list the phrases: "The thief stole the gems", "from the vault in the bank", ".", "turned out to be the best part", "and how he did it". Wait, maybe the correct arrangement is: "The thief stole the gems from the vault in the bank, and how he did it turned out to be the best part." Wait, no, the model has a "but" clause. Wait, the user's task is to use the words and phrases to create a new sentence that matches the model. The model's structure is [Main clause], but [whether/how... remains to be seen (or in this case, turned out to be the best part)]. Let's take the phrases: "The thief stole the gems from the vault in the bank" (main clause), then "how he did it" (the subordinate clause part), and "turned out to be the best part". So combining them: "The thief stole the gems from the vault in the bank, and how he did it turned out to be the best part." Wait, but the model has "but". Maybe a typo, but with the given phrases, we can form: "The thief stole the gems from the vault in the bank, and how he did it turned out to be the best part." Or maybe "The thief stole the gems from the vault in the bank, but how he did it turned out to be the best part." Either way, the key is to arrange the phrases into a sentence with a main action and a clause about how it was done and the result, matching the model's structure of a main clause and a subordinate clause about an unknown (or in this case, a result) part.

Answer:

The thief stole the gems from the vault in the bank, and how he did it turned out to be the best part.
