Four runners—Dan, Eli, Finn, and Gus—finished a race in four distinct positions without any ties. Dan finished before Eli. Finn finished after Gus. Gus finished before Dan. What was the exact finishing order from 1st to 4th?
Gus, Dan, Eli, Finn
Gus finished before Dan (Gus -> Dan). Dan finished before Eli (Dan -> Eli), giving Gus -> Dan -> Eli. Finn finished after Gus, but since Gus is already before Dan and Eli, Finn must be last after Eli (Gus -> Dan -> Eli -> Finn).
