Final answer:
Nonverbal communication is influenced by cultural background and can be imprecise due to varied interpretations. Its meaning varies across cultures and situations, which internal auditors must consider.
Step-by-step explanation:
When evaluating communication, an internal auditor should be aware that nonverbal communication is not independent of a person's cultural background; rather, it is deeply influenced by it.
This form of communication includes a variety of signals such as body language, facial expressions, and gestures, which can vary significantly across different cultures. For instance, a smile often indicates positivity in the U.S., whereas it may be considered rude in other cultures if you do not know the person well.
Moreover, nonverbal signals like a thumbs-up can be seen as positive in some places, like the United States, while being considered offensive in countries like Russia and Australia.
Therefore, we can conclude that the second option, stating that nonverbal communication is often imprecise, is the most accurate. Its imprecision stems from its varied interpretations, which can depend on cultural context, the situation, and the individuals involved.
Nonverbal communication does not always convey more truthful responses than verbal communication, and it can sometimes express just as much, if not more, information. Thus, it's essential for an internal auditor to be cognizant of these nuances when assessing communication.
