Q. SPLINE is a smooth curve passing through or near a given set of points
R. PLINE creates straight line segments, are segments or both
S. PLINE can be closed only when its start and end points are coincident and tangent
T. PLINE allows adjusting the width and curvature of its multiline segments
U. SPLINE can be exploded into smaller segments
