Out of the options up there, some decisions that are helpful to make before you give an oral presentation is to make note cards. These will help you stay on track and help you if you forget what you were talking about. You do not want to do the other options because those are last minutes changes and you might forget you added them and say what you previously had.
For number 1, your option is correct (B). "Doggedly" is synonymous with "persistent," so "with great determination" matches that.
For number 2, your option is correct (D). "Stoutly" means "strong" and "sturdy," so "solid" would also work.
For number 3, your option is incorrect. The correct answer is B. "Boisterous" and "rowdy" both mean energetic and noisy. Since the children were bouncing off the walls, they were indeed energetic, boisterous, and rowdy.
