Suppose "Stairway to Heaven" is a song by the English rock band Led Zeppelin, released in late 1971. It was composed by the band's guitarist Jimmy Page and vocalist Robert Plant for their untitled fourth studio album (often called Led Zeppelin IV). The song features a gentle opening with acoustic guitar and a crescendo with electric instruments, known for its memorable guitar solo and mystical lyrics.
Can we infer that "Stairway to Heaven is a fast-paced rock song."? Yes, no, or maybe?
