Final answer:
Lists of action items in a project plan and steps in a chemical reaction would benefit most from being formatted with bullets or numbering.
Step-by-step explanation:
The two kinds of lists that would benefit most from being formatted with bullets or numbering are:
- Lists of action items in a project plan: By using bullets or numbering, it becomes easier to visualize and track the progress of individual action items in a project plan.
- Steps in a chemical reaction: Bullet points or numbering can help clearly outline and sequence the steps involved in a chemical reaction, making it easier to understand and follow.
