Four runners—Anna, Ben, Cole, and Dana—finished a race. Anna finished before Ben. Cole did not finish first or last. Dana finished immediately after Ben. Who won the race?
Anna
Dana finished immediately after Ben, so they form a block [Ben, Dana]. Anna finished before Ben, so Anna must be before that block. Cole cannot be 1st or 4th, placing him 2nd. The only order satisfying all conditions is 1st: Anna, 2nd: Cole, 3rd: Ben, 4th: Dana.
