A word puzzle that contains two pairs of words having some relationship to each other.

Which one is right
Sudoku
chess
analogy
context clues

The correct answer is analogy.

Sudoku and chess are both types of puzzles or games. They do not have a direct relationship to each other but are similar in the sense that they require problem-solving and logical thinking skills.

On the other hand, analogy and context clues have a closer relationship. Both are related to understanding and interpreting language. Analogy involves comparing two pairs of words to find a relationship, while context clues refer to using the surrounding words or phrases to understand the meaning of an unknown word.
