The three correct answers regarding how in-text citations are formatted in MLA style are:
- in brackets - In MLA style, in-text citations are typically enclosed in parentheses.
- outside the closing period - In MLA, the in-text citation is placed before the closing period of the sentence.
- inside the closing period - This option is not accurate, as the citation should come before the closing period.
However, you want only the correct responses regarding formatting, so the final correct selection would be:
- in parentheses - The citation is indeed included in parentheses.
- outside the closing period - The in-text citation is placed before the closing period.
- at the end of a sentence - In-text citations usually appear at the end of a sentence where the referenced material is discussed.
Therefore, focusing on the accurate context: the citations are formatted in parentheses, placed just before the closing period of a sentence. The correct selections should ideally reflect the standard citation rules correctly rather than repeating the only informative option available.
