Answer:
In addition to a striking <u>style and design</u>, it should be noted that if you have already done the research, it is correct to add a <u>cover, an introduction to the project and the conclusions</u>.
Explanation:
The cover contains the title of the investigation, the name of the person who made the slides and the most important information that should be attached to some slides.
The introduction is an orientation point that indicates what the work will be about.
The conclusions: it is a small summary of everything that was seen and understood about the project.
With a cover, an introduction, an investigation, a summary and conclusions, the slides would be left with everything they are supposed to have to expose them.
