The Examiners are there to help you, to answer any questions they can, and to help you understand the task you are to perform.  If you feel you would like further clarification, or do not feel comfortable speaking to an Examiner about a particular issue, there is a Moderator at each exam sitting.  The Moderator is there as a representative of NACOR to ensure the exams run the same way in each location, and they are there to provide support to candidates.  If you have any concerns during the examination, no matter how big or small, you are encouraged to discuss those concerns with the Moderator at the examination sitting as this is when help can be provided.  If you call or email the NACOR office after the exams are over there is nothing that can be done to clarify or help with a situation that came up for you.
