Select the text command to emphasize a block quotation.

To emphasize a block quotation, indenting the text is an effective method as it visually distinguishes the quoted material from the surrounding text. This indentation provides a clear indication to readers that the text is a quotation, setting it apart as a separate thought or voice.

Using indentation not only aids in readability, but it also adheres to standard typographic conventions used in writing and publishing, where block quotations are often indented to indicate they are longer excerpts from another work. This format helps maintain the flow of the document while highlighting important information.

While aligning text may change its position on the page, and inserting style options could potentially alter its appearance, these actions do not specifically prioritize the differentiation of a block quotation. Formatting text can also apply various styles but may not inherently clarify that the text is a quotation. Thus, indenting the text serves the primary purpose of emphasizing block quotations effectively.
