Answer:
The page number
Step-by-step explanation:
When you are creating an in-text citation, you need to include two crucial pieces of information: the author's name and the page number where you find the information that you are citing. This is included in parentheses immediately after the information you have taken from the text. However, sometimes the author's name is mentioned previously as a way to introduce the quote. In this case, only the page number has to be included in parentheses.
