    Use a nested loop. The outer one iterates over sounds, while the inner one iterates over the current element from sounds.

    Of course, in that particular example, it would probably be easiest just to directly reference the elements of the inner arrays. That way, you could just print

  • $inner[0], $inner[1]
  • (note that I've never used Ruby, so I don't know how arrays are indexed, let alone printing syntax).
