Question 4: All detectives are Gardaí. Some Gardaí drive patrol cars. Which conclusion is definitely true?
- Some Gardaí are detectives (Correct answer)
- All detectives drive patrol cars
- No detectives drive patrol cars
- All Gardaí are detectives
Correct answer: Some Gardaí are detectives
Since all detectives are Gardaí, detectives are a subset of Gardaí. Therefore 'some Gardaí are detectives' is always true.
Question 5: What is the next shape in a sequence of: circle, triangle, circle, square, circle, pentagon, circle, ___?
- Hexagon (Correct answer)
- Triangle
- Circle
- Square
Correct answer: Hexagon
After each circle, a polygon with one more side appears: triangle (3), square (4), pentagon (5), hexagon (6).
Question 6: A criminal is described as tall, with a beard, and wearing a red jacket. Witness B says the person was short. What does this tell us?
- Witness B's description contradicts the other description (Correct answer)
- Both witnesses are wrong
- The criminal had a beard and red jacket but was short
- Witness B is lying
Correct answer: Witness B's description contradicts the other description
Witness B's description of 'short' directly contradicts the 'tall' description. We can only say there is a contradiction — we cannot determine who is correct.
