Q1: Whole circle bearing of a line is preferred to a quadrantal bearing merely because

ANS:B - bearing is completely specified by an angle

The whole circle bearing of a line is preferred to a quadrantal bearing merely because bearing is not completely specified by an angle. Quadrantal bearings provide only partial information about the direction of a line since they only specify the direction with respect to one of the four quadrants (NE, SE, SW, NW). Whole circle bearings, on the other hand, specify the direction of the line in terms of degrees measured clockwise from the north direction around the entire circle, providing a complete and unambiguous representation of the direction.
