Crossover Aptitude Test Spatial Reasoning: Odd One Out 3 — Questions and Answers
Question 1: Four patterns each show a grid with shaded cells. A) Top-left and bottom-right shaded B) Top-right and bottom-left shaded C) All four corners shaded D) Only top-left shaded
- Top-left and bottom-right shaded
- Top-right and bottom-left shaded
- All four corners shaded
- Only top-left shaded (Correct answer)
Correct answer: Only top-left shaded
Options A, B, and C all show symmetrical shading patterns (diagonal, anti-diagonal, or all corners), while D shows asymmetric shading of just one corner.
Question 2: Which is the odd one out among flat 2D shapes? A) Sphere B) Circle C) Ellipse D) Ring (annulus)
- Sphere (Correct answer)
- Circle
- Ellipse
- Ring (annulus)
Correct answer: Sphere
Circle, ellipse, and ring (annulus) are all flat 2D shapes, while a sphere is a three-dimensional solid.
Question 3: Four figures show a shape with an arrow indicating rotation. Which rotation produces a figure that does NOT match the original? A) Square rotated 90° B) Equilateral triangle rotated 120° C) Regular hexagon rotated 60° D) Rectangle rotated 90°
- Square rotated 90°
- Equilateral triangle rotated 120°
- Regular hexagon rotated 60°
- Rectangle rotated 90° (Correct answer)
Correct answer: Rectangle rotated 90°
A square at 90°, equilateral triangle at 120°, and regular hexagon at 60° all map onto themselves exactly, but a rectangle rotated 90° produces a different orientation (wider vs. taller).
Question 4: Each set contains four geometric shapes. Which shape is the odd one out? A) Parallelogram B) Rhombus C) Rectangle D) Trapezoid
- Parallelogram
- Rhombus
- Rectangle
- Trapezoid (Correct answer)
Correct answer: Trapezoid
Parallelogram, rhombus, and rectangle all have two pairs of parallel sides (they are all parallelograms), while a trapezoid has only one pair of parallel sides.
Question 5: Four images show a cross-section cut of a 3D shape. Which cross-section is the odd one out? A) Circle (cross-section of a sphere) B) Circle (cross-section of a cylinder) C) Circle (cross-section of a cone) D) Square (cross-section of a cube)
- Circle (cross-section of a sphere)
- Circle (cross-section of a cylinder)
- Circle (cross-section of a cone)
- Square (cross-section of a cube) (Correct answer)
Correct answer: Square (cross-section of a cube)
A sphere, cylinder, and cone can all produce a circular cross-section, while a cube's cross-section is a square (or other polygon), never a circle.
Question 6: Which figure is the odd one out based on the number of enclosed regions? A) Figure-8 shape B) Letter 'B' outline C) Letter 'O' outline D) Letter 'P' outline
- Figure-8 shape (Correct answer)
- Letter 'B' outline
- Letter 'O' outline
- Letter 'P' outline
Correct answer: Figure-8 shape
The figure-8 encloses two separate regions, while the outlines of 'B' (two loops), 'O' (one loop), and 'P' (one loop) enclose only complete bounded areas without self-intersecting.
Question 7: Four paper-folding sequences are shown. Three produce the same final shape; one does not. The odd one out produces: A) A triangle when folded diagonally once B) A smaller square when folded in half twice C) A rectangle when folded once lengthwise D) A triangle when folded diagonally twice
- A triangle when folded diagonally once
- A smaller square when folded in half twice (Correct answer)
- A rectangle when folded once lengthwise
- A triangle when folded diagonally twice
Correct answer: A smaller square when folded in half twice
Folding diagonally once, lengthwise once, and diagonally twice all result in triangular or rectangular shapes from a square paper, but folding in half twice produces a smaller square — a different shape category.
