When incorporating complex information into a report,how can you introduce new,important topics?

A) Avoid transitions to avoid confusion with previous material
B) Use third level headings
C) Add links to additional information
D) Include review sections
E) Include preview sections

Including preview sections is the best choice to introduce new, important topics as it provides a brief summary of what will be discussed. This allows the reader to have an overview of the content and be prepared for the upcoming information. Choices A, C, and D do not specifically address the introduction of new topics, while using third level headings may be useful, it may not be enough to provide context for the new information.
