Answer:
The correct answer is Memorize the presentation.
Explanation:
Not all people have the ability to memorize or even the time necessary to do so. Some people when they start in the speaking activity, their study technique is to write their speech and memorize each paragraph. Without a doubt, to do the above it will take you a good time, even days if necessary.
Among the disadvantages of memorizing are:
It happens that you lose the naturalness of the exhibition. The audience notices when you are trying to remember something you previously prepared. There are phrases that we use and that escape us like: "let's see" or "just a moment". Those phrases show the audience that we are looking for the answer in our memory. If we forget a bit, we can lose the common thread and go blank, as if it were a chain with a broken link.
Also, when we learn a speech in its entirety, it speaks to our memory and not our heart. In this case, it is very likely that the speech will come out mechanically, since we pay more attention to saying it correctly than to approaching and connecting with the public.
