This document discusses the differences between active and passive voice and provides guidance on when to use each. It emphasizes that active voice is generally preferable as it uses stronger verbs and makes writing more concise and clear by highlighting the subject performing the action. However, passive voice can also be used effectively in certain situations, such as when the actor is unknown or unimportant, or when a more objective tone is desired. Overall, the document encourages using active voice most of the time but understanding when passive voice may also be appropriate.
