In an odd-one-out question: circle, oval, ellipse, square. Which is the odd one out?
Answer: Square
Circle, oval, and ellipse all have curved edges with no corners; a square has four corners, making it the odd one out.
A code in an abstract test maps shapes to numbers: triangle=3, square=4, pentagon=5. What does hexagon equal?
Answer: 6
The code maps each shape to its number of sides; a hexagon has 6 sides, so hexagon = 6.
In a classification question: which shape does NOT belong with the others — equilateral triangle, isosceles triangle, right triangle, square?
Answer: Square
All triangles have three sides; a square has four sides and does not belong in the group of triangles.
If shape A implies shape B, and shape B implies shape C, and shape C is absent, what can you conclude?
Answer: Shape A is absent
By the contrapositive: if C is absent (¬C), then B is absent (¬B), then A is absent (¬A).
An abstract test shows: all large shapes have thick borders, some thick-bordered shapes are triangles. Shape R is a large triangle. What can be deduced?
Answer: Shape R has a thick border
The first rule states all large shapes have thick borders; Shape R is large, so it must have a thick border.
In a logical sequence, figures that are both shaded AND large belong to Class X. Figure T is shaded but small. Does Figure T belong to Class X?
Answer: No
Class X requires both shaded AND large; Figure T is shaded but small, failing the large condition, so it does not belong to Class X.
