Arranging these sentences poses a challenge because both 3 and 2 could serve as possible opening sentences. Sentences 1 and 4 naturally form a pair since in 4 there is a reference to '…that certainly felt like a threat…'. To comprehend this statement, it needs to be linked to 1, where there is an idea that resembles a threat, conveyed in the quote "enjoy it while it lasts." Therefore, there are two conceivable sequences: 2314 and 3214. Although the official answer is given as 2314, it is worth noting that 3214 could also be a valid sequence.
