Answer to Question 1

TRUE

Answer to Question 2

Preliminary parts add formality, emphasize report content, and aid the reader in locating information in the report quickly and in understanding the report more easily. The title page of the report is a good example of the added formality purpose. The executive summary repeats the report's content in a summarized format and also helps in understanding the report more easily. The contents and figures pages aid the reader in locating information quickly.
