Answer to Question 1

A portable document format (PDF) file allows the writer to preserve the design of a document in a format that can be used on a variety of computer platforms. Such files are useful for activity reports because they are easy to store, they retain the look of the original, and they can be electronically signed.

Answer to Question 2

White papers are miniature reports that are written objectively to inform people about a technical or scientific subject. They are often used to inform the readers about important issues.
