You will principally refer to the central idea to select the material to include in the speech, based on the relevancy of the material. The secondary points to consider in selecting the items to present are: (i) What is the most interesting? (ii) What is the emotional impact? (iii) Which is briefest? (iv) Which is most illustrative? (v) Which has the most authority?
