A more thorough explanation:

Definition: Revision is the act of carefully reviewing something in order to make corrections or improvements.

Examples:

• A student revises their essay before submitting it to their teacher.
• A company revises their marketing strategy to improve sales.
• A group of people revise the bylaws of their organization to make them more effective.
• A court-martial may be revised if there was an improper or inconsistent action concerning the findings or sentence.

The examples illustrate how revision can be applied in different contexts, such as academic writing, business, and law. In each case, revision involves carefully reviewing something and making changes to improve it. Whether it's revising an essay to improve its clarity and coherence, revising a marketing strategy to increase sales, or revising a governing document to make it more effective, the goal is always to make something better through careful review and correction.
