I think on my easy and normal games it took technology and health. Today, however, it said "Gong grants vision" which I didn't understand. Then when I started to scan for things for the kids I went too far and saw the graveyard and apparently the spirit of one of the dead buried there was standing there. I tried to drag the gong-ringer over to see if he's do anything with the spirit but he just started "reflecting" and she vanished soon after.
