During the interpretation phase, what is not a primary focus?	Identifying manufacturing defects	Classifying indications	Evaluating surface irregularities	Determining the cause of bleed-out
False indications can often be traced back to:	Part defects	Environmental factors	Operator errors	Design flaws
The importance of classifying indications during interpretation lies in:	Identifying false indications	Evaluating surface irregularities	Preventing false indications masking relevant ones	Determining the cause of bleed-out
