The following question, consist of two words each that have a certain relationship to each other, followed by four lettered pairs of words. Select the lettered pair that has the same relationship as the original pair of words: South : North-West :: West : ?

The correct answer is: A. South-west.

The relationship between “South” and “North-West” is that they are two compass directions that are 90 degrees apart. The same is true for “West” and “South-West”.

Option B, North-East, is not correct because it is not 90 degrees apart from West. Option C, East, is not correct because it is not 90 degrees apart from West. Option D, South, is not correct because it is the same compass direction as West.
