Final answer:
An auditor would likely give broader consideration to a deviation initially concealed by a forged document, as this implies intentional wrongdoing and has more serious implications than a simple oversight.
Step-by-step explanation:
An auditor should consider qualitative aspects of deviations besides just their frequency. In this scenario, the deviation most likely to receive broader consideration would be one that was initially concealed by a forged document. This kind of deviation indicates a potential for intentional wrongdoing or fraud, which has more serious implications than a deviation that is an oversight or error. Deliberate deception, such as forgery, suggests that the controls cannot be relied upon to prevent or detect misstatements.
A deviation that is identical to one from a prior year's audit might also raise concerns about the persistent nature of the control issue. However, a deviation caused by an employee's oversight might be seen as less severe unless it indicates a systematic problem, and a single deviation may not warrant extensive scrutiny unless it points to a larger issue.
