Size distortion is a result of:
 
 decreased SID
  increased OID
  change in focal spot size
  angulation of the tube

Question 2

A part imaged that is not aligned parallel to the image receptor and perpendicular to the beam results in:
 
 poor recorded detail
  elongation
  foreshortening
  magnification

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.
