Which of the following statements about the 'method of ordinates from the long chord' for setting out simple curves are correct? Statement I: The long chord is divided into an even number of parts and offsets are set out perpendicularly at these divisions. Statement II: For each offset, a formula involving the radius and distance from the chord's midpoint is used. Statement III: In this method, all offsets are always equal, regardless of the curve's radius.
