The sector reference system comprises how many main quadrants and subquadrants per main quadrant?

• A. Four main quadrants, each containing four subquadrants
• B. Eight main quadrants, each with two subquadrants
• C. Two main quadrants, each with eight subquadrants
• D. Sixteen main quadrants with no subquadrants

Answer: (A)

In this sector reference system, space is divided into four broad sectors around the center, which you can think of as four main quadrants. Each of these broad quadrants is then subdivided into four smaller pieces, giving four subquadrants inside every main quadrant. So the structure is four main quadrants, with four subquadrants per main quadrant. This hierarchical layout provides a clear way to describe a location by naming both the broad quadrant and the specific subquadrant within it. The other options would imply a different division pattern, not the nested arrangement described here.
