Intelligence Test Intelligence 5 — Questions and Answers
Question 1: Which of the following sequences follows the rule 'add the two previous numbers to get the next'?
- 2, 4, 8, 16, 32
- 1, 1, 2, 3, 5, 8 (Correct answer)
- 3, 6, 9, 12, 15
- 5, 10, 15, 20, 25
Correct answer: 1, 1, 2, 3, 5, 8
The sequence 1, 1, 2, 3, 5, 8 is the Fibonacci sequence, where each number is the sum of the two preceding numbers.
Question 2: If FRIEND is coded as GSJFOE, how is HOUSE coded?
- IPVTF (Correct answer)
- IOVSE
- IPUSE
- IOUEF
Correct answer: IPVTF
Each letter is shifted one place forward in the alphabet: F→G, R→S, I→J, E→F, N→O, D→E; similarly H→I, O→P, U→V, S→T, E→F gives IPVTF.
Question 3: Which psychological theory proposes that intelligence is not a single fixed trait but includes components like processing speed, working memory, and reasoning ability?
- Spearman's g factor theory
- Cattell-Horn-Carroll (CHC) theory (Correct answer)
- Vygotsky's sociocultural theory
- Maslow's hierarchy of needs
Correct answer: Cattell-Horn-Carroll (CHC) theory
The Cattell-Horn-Carroll theory is a hierarchical model of cognitive abilities that breaks intelligence into multiple broad and narrow abilities.
Question 4: A clock shows 3:15. What is the angle between the hour and minute hands?
- 0°
- 7.5° (Correct answer)
- 15°
- 22.5°
Correct answer: 7.5°
At 3:15, the minute hand is at 90° and the hour hand is at 97.5° (3 hours × 30° + 15 min × 0.5°), giving a difference of 7.5°.
Question 5: Which term describes the mental shortcut where people judge the likelihood of an event based on how easily an example comes to mind?
- Representativeness heuristic
- Availability heuristic (Correct answer)
- Anchoring heuristic
- Framing effect
Correct answer: Availability heuristic
The availability heuristic is a mental shortcut where people estimate probability based on how quickly relevant examples come to mind.
Question 6: Which of the following best demonstrates spatial reasoning ability?
- Memorizing a list of vocabulary words
- Mentally rotating a 3D object to determine how it looks from another angle (Correct answer)
- Solving a logic word problem
- Recalling the steps of a recipe from memory
Correct answer: Mentally rotating a 3D object to determine how it looks from another angle
Mental rotation of 3D objects is a classic measure of spatial reasoning, the ability to think about objects in three dimensions.
Question 7: Five friends — Alice, Bob, Carol, Dave, and Eve — sit in a row. Alice sits next to Bob. Carol sits at one end. Dave does not sit next to Carol. Who must sit next to Carol?
- Alice
- Bob
- Eve (Correct answer)
- Dave
Correct answer: Eve
Carol is at one end; Dave cannot be next to Carol, and Alice must be next to Bob, so Eve must be the one sitting next to Carol.
