Step-by-step explanation:
Unjustified text is preferred for all the following types of documents except:

- Academic papers
- Business reports
- Newspaper articles
Unjustified text is not preferred for documents that require a formal tone and adherence to standard formatting guidelines. This includes academic papers, which often require a specific formatting style such as MLA, and business reports, which typically follow a standardized form. On the other hand, legal documents and newspaper articles may have more flexibility in their formatting and may use justified or unjustified text depending on the specific context.
