The first thing that might catch your eye is the position of the smiley face above the grid, which might resemble the Minesweeper interface, which is thematic to the puzzle title and the nature of the questions.

If you are able to make that logical leap, the rest of the puzzle is a simple Google search for the answers and solving the Minesweeper grid for the positions of the mines. The letters corresponding to the mine positions (marked in red below) will spell your answer, NAVAL SHIPS.
