Which search pattern is best described as locating an object at a known distance from another object?

• A. Spiral Search
• B. Line Search
• C. Zone Search
• D. Grid Search

Answer: (A)

When you have a target at a known distance from a reference point, you want to search in a pattern that keeps that relationship to the point while you expand the area. A spiral search achieves this by starting at the known position and moving outward in expanding rings, with the spacing between rings set so you cover all locations at that specific distance from the reference. This creates a continuous, systematic sweep around the point, ensuring you don’t miss areas at the precise radius you’re considering. The other patterns serve different needs: line search sweeps straight paths, good for long, narrow spaces; zone search divides the area into larger zones and sweeps them; grid search covers the space in square blocks. None of those focus on maintaining a fixed distance from a reference point as effectively as a spiral does.
