Best practice
To add impact, follow "this is a danger" with a 'that' clause explaining the potential consequences: "This is a danger that demands immediate attention."
Common error
Avoid simply stating "this is a danger" without explaining the source or potential impact of the danger. Always provide enough information for the reader to understand the threat and its implications. For instance, instead of saying "this is a danger", specify the threat, like "the lack of funding is a danger to the project's success".
