AN: Here's the solution for this puzzle for anyone having trouble. (:
"Alright, let me see..." Nancy mumbled as she looked at the switches. "One in each group... That seems easy enough."
First she pressed switches one, four, and five. Nothing happened. "Hmm..." Remembering the next step she pressed the green button. The machine beeped, not signaling whether she had done it right or wrong.
"I guess I'll just keep going. Next is…" She looked them over again and pressed seven, nine, and eleven." Then she had a problem. There weren't enough switches. "Guess I'll just press this one again. Two… Three… Eleven… and… Three… Eight… Eleven."
Beep. The machine turned on.
