Final answer:
Parenthetical documentation is required for direct quotes and optional for paraphrased information, listing the author's last name and page number without replacing the need for a Works Cited page. option 4 is the correct answer.
Step-by-step explanation:
When you use parenthetical documentation at the end of a sentence, the correct options include that it is always necessary for direct quotes (Option 1) and it is optional for paraphrased information (Option 3). Parenthetical documentation should contain essential information such as the author's last name or the title of the work if the author is unknown, and the publication date or page number where the original material can be found, but it does not include the author's phone number nor does it replace the need for a Works Cited page (Option 4). Here's an example of how to use parenthetical documentation:
- According to Smith (2012), "students often struggle with MLA format" (p. 78).
- "Students often struggle with MLA format" (Smith 78).
It is crucial that every parenthetical citation points readers towards a detailed Works Cited page entry, and vice versa, to avoid plagiarism and ensure that readers can find the original source information.
