My presentation for me, was a little complicated because I have many things to do, evaluations in my other class when I can read many text,  as well as, im not accustomed to memorize, because the university teach us that the ideal is not do it, as well as, in archaeology when I must memorioze, only do it whit a specific data, if example, archaeological sites and dates. On the other hand, if the objetive, is evaluate our speaking in a conversation, I doubt that explain a text memorized help to this, because is not natural and stream, so, read a paper,  for me, no change  the result.
