In a testing scenario, which demand is dominant if the deaf client distracts the interpreter to talk to friends about answers?

The dominant demand in this scenario is interpersonal. This is because the deaf client is engaging with the interpreter in a way that shifts the focus from the testing situation to a personal interaction. The chatter about answers reflects a social or personal connection that interferes with the interpreter's role in facilitating the communication process.

In interpreting practice, interpersonal demands occur when the relationship dynamics between the interpreter and the client come into play, particularly when personal interactions or distractions can influence the interpreting process. The interpreter's responsibility is to maintain the integrity of the communication environment, and distractions from social interactions can create challenges in fulfilling that role.

The other demands—professional, ethical, and emotional—while relevant to the broader context of interpreting, do not specifically capture the nature of the distraction caused by the client's interaction with friends. Professional demands relate to adherence to standards and practices in interpreting, ethical demands involve maintaining confidentiality and impartiality, and emotional demands address the feelings and reactions of either the interpreter or the client. In this case, the direct nature of the client's distraction points clearly to the interpersonal aspect of the interaction.
