Final answer:
Justified text and centered text are distinct formats; justified text aligns evenly along left and right margins, while centered text aligns in the middle of the page. Justified text is often used for block quotations and academic contexts, while centered text is commonly used for headings and titles.
Step-by-step explanation:
Justified text and centered text are not the same text format. Justified text is aligned evenly along both the left and right margins, giving it a clean and formal look often used in printed materials like newspapers or books. To format a block quotation, you might justify the text and indent it 1/2" without using quotation marks, with an in-text citation following the block. In contrast, centered text is aligned horizontally in the middle of a page or column and is often used for titles or headings.
For instance, when you format a business letter, block formatting is used where all the text is left-justified, streets no indentation at the beginning of paragraphs, and employs single spacing with double spacing between paragraphs. This is different from both justified and centered text formatting.
Additionally, in academic writing or when discussing texts, one might justify their comparison of texts by showing similarities first and then detailing differences to illuminate understanding, where 'justify' is used in the context of argumentation, not text alignment.
When considering the layout of a book, margin space is often utilized for notes, which aids in maintaining a smooth reading flow, distinct from the discussion of text justification or centering.
