Worked practice questions
In analogy questions, the symbol '::' between two pairs means
- Both pairs share the same kind of relationship
- Both pairs are equal in numerical value
- Both pairs add up to the same result
- Both pairs are written in alphabetical order
Show answer and solution
Correct answer: A. Both pairs share the same kind of relationship
1. The chapter explains the meaning of :: in its examples.
2. It says first pair and second pair share a similar relationship.
3. It does NOT say they are numerically equal.
4. So option A is correct.
