Answer to Question 1

increased OID

Rationale: Size distortion can occur with increased OID resulting in magnification of the part.

Answer to Question 2

foreshortening

Rationale: Foreshortening occurs when a part is not aligned to the long axis of the IR and perpendicular to the beam. Elongation occurs when the tube is angled across a part.
