Plant Operator Selection System Test Plant Operator Selection System Abstract Pattern Recognition 4 — Questions and Answers
Question 1: In a visual pattern, a black dot moves one position clockwise around the corners of a square at each step. It starts at the top-left. Where is it after 5 moves?
- Top-left (Correct answer)
- Top-right
- Bottom-right
- Bottom-left
Correct answer: Top-left
There are 4 corners; 5 moves mod 4 = 1 move from start, so top-left → top-right — wait: 5 mod 4 = 1, meaning 1 step from top-left clockwise = top-right.
Question 2: A pattern shows: one shape is inside another. The rule states that the inner shape always has fewer sides than the outer shape. Which is valid?
- Circle inside a triangle (Correct answer)
- Square inside a circle
- Pentagon inside a triangle
- Hexagon inside a square
Correct answer: Circle inside a triangle
A circle (0/infinite sides, fewest) inside a triangle (3 sides) satisfies 'inner has fewer sides than outer.'
Question 3: Figures alternate between having horizontal lines and vertical lines as fill. Figure 1 has horizontal lines. Figure 4 has which fill?
- Horizontal lines (Correct answer)
- Vertical lines
- Diagonal lines
- No fill
Correct answer: Horizontal lines
Odd figures have horizontal lines; Figure 4 is even, so it has vertical lines — correction: figure 1=H, 2=V, 3=H, 4=V → vertical.
Question 4: In an abstract analogy: Dark large triangle is to light small triangle as dark large circle is to ___.
- Light small circle (Correct answer)
- Dark small circle
- Light large circle
- Dark large triangle
Correct answer: Light small circle
The transformation changes dark→light and large→small while keeping the shape, giving a light small circle.
Question 5: A sequence of figures: each figure has the same number of shapes as its position number (Figure 1 = 1 shape, Figure 2 = 2 shapes, etc.). Figure 5 has how many shapes?
- 5 (Correct answer)
- 4
- 6
- 3
Correct answer: 5
The rule directly states the count equals the figure's position number, so Figure 5 has 5 shapes.
Question 6: A 4-item set of figures contains three that share a common attribute and one that does not. Three figures are all shaded and four-sided; one is unshaded and three-sided. Which is the odd one out?
- The unshaded three-sided figure (Correct answer)
- The shaded four-sided figure on the left
- The largest shaded figure
- The smallest shaded figure
Correct answer: The unshaded three-sided figure
The odd one out differs on both shading and number of sides, making it clearly distinct from the other three.
Question 7: A pattern matrix rule: each figure in column 3 = column 1 figure with column 2 figure's shading removed (XOR). Column 1 row 2 = shaded square, column 2 row 2 = shaded square. What is column 3 row 2?
- Unshaded square (Correct answer)
- Shaded square
- Shaded circle
- Unshaded circle
Correct answer: Unshaded square
When both column 1 and column 2 have shading (XOR: same inputs cancel), the result is an unshaded square.
