Which of the following should you look for when proofreading a document for writing errors?

A) Style decisions
B) Page numbering errors
C) Line and page breaks
D) Adherence to company standards
E) Typographical mistakes

When proofreading a document, the most important thing to look for is typographical errors, such as spelling mistakes, punctuation errors, and formatting inconsistencies. While it is also important to check for adherence to company standards, style decisions, page numbering errors, and line and page breaks, these are all secondary concerns compared to the need to ensure that the text is error-free and communicates the intended message to the reader.
