Answer 1: APPLE
Trace APPLE from row 3, column 4. Move right to row 3, column 5 for the first P, continue right to row 3, column 6 for the second P, turn down to row 4, column 6 for L, and finish by moving left to row 4, column 5 for E. The two identical middle letters occupy consecutive cells, so no jump or diagonal is needed.
Follow these cells for the exact comparison: 1 at row 3, column 4; 2 at row 3, column 5; 3 at row 3, column 6; 4 at row 4, column 6; 5 at row 4, column 5. This five-cell route makes two turns across three straight segments. It uses two cells on the board edge and leaves 21 open cells for the other three answers.
