The Stuck Excavator Riddle
You and three other experienced heavy equipment operators—Jake, Lisa, and Mike—are working on a construction site. One day, a large excavator gets stuck in deep mud near the center of the site. Each operator was running a different machine that day:
• A bulldozer
• A wheel loader
• A motor grader
• A dump truck
Each of you was assigned to a different section of the site:
• The north sector
• The south sector
• The east sector
• The west sector
Facts:
1 Lisa was not operating the bulldozer or the motor grader.
