In this straightforward example of a Raven’s Matrix, the key is identifying the two changing factors that create the different figures:
- Outline: the shape of the figure — square, circle, and diamond
- Filling: the interior pattern — empty (white), striped, and solid (black)
Once these factors are established, we can observe their variation across the matrix.
Each row and column contains all three versions of both factors. The ascending diagonals maintain the same filling, while the descending diagonals maintain the same outline.
The missing piece lies at the intersection of the rightmost column and bottom row. The outline missing from these is a square, and the filling missing is striped. Therefore, the answer must be a striped square.
Alternatively, considering the matrix as a whole:
With three outline variations and three filling variations, there are nine possible combinations. The matrix displays all combinations exactly once, except for the striped square.
Hence, the correct answer is C.
