premise: "Sultans of Swing" is a song by British rock band Dire Straits from their eponymous debut album, which band frontman Mark Knopfler wrote and composed. Although it was first released in 1978, it was its 1979 re-release that caused it to become a hit in both the UK and U.S.
hypothesis: "Sultans of Swing" is a song by British rock band Dire Straits that was released and re-released only one years apart.
reason: there was only one year between 1978 and 1979 and I'm really surprised the AI did not get this one correct so I'm not sure why, maybe because it couldn't make a connect to the number one and the word year.
