Task: Question Generation
Input (English): A straight flush is a poker hand containing five cards of sequential rank, all of the same suit, such as Q♥ J♥ 10♥ 9♥ 8♥ (a ``queen-high straight flush''). It ranks below five of a kind and above four of a kind. As part of a straight flush, an ace can rank either above a king or below a two, depending on the rules of the game. Under high rules, an ace can rank either high (e.g. A♥ K♥ Q♥ J♥ 10♥ is an ace-high straight flush) or low (e.g. 5 4 3 2 A is a five-high straight flush), but cannot rank both high and low in the same hand (e.g. Q♣ K♣ A♣ 2♣ 3♣ is an ace-high flush, not a straight flush). Under deuce-to-seven low rules, aces can only rank high, so a hand such as 5♠ 4♠ 3♠ 2♠ A♠ is actually an ace-high flush. Under ace-to-six low rules, aces can only rank low, so a hand such as A♥ K♥ Q♥ J♥ 10♥ is actually a king-high flush. Under ace-to-five low rules, straight flushes are not recognized, and a hand that would be categorized as a straight flush is instead a high card hand.
Output (English): is an ace 2 3 4 5 a straight?
