Answer:
An introduction, two key findings paragraphs, a recommendation paragraph, and a conclusion
Step-by-step explanation:
The structure above would be the best for an informative report.
The introduction paragraph gives the reader an idea of what the report will be about.
The two key findings paragraphs are the most important because they provide the information, or the evidence of the informative report.
The recommendation paragraph is a normative statement that stems from the key findings paragraphs, and the conclusion is a wrap-up of what was told in the text.
Overall, this structure is very good for an informative report.
