To follow MLA citation rules properly, the author of this essay needs to include a page number after the author’s name. In MLA style, citations typically include the author's last name and the page number from which the information was taken. For example, the citation should look like this: (Toles page number).
The other options are not correct:
- Adding a citation after each sentence is not necessary and can lead to over-citation.
- Removing the reference to the name of the doctor would not adhere to proper attribution.
- Placing an end quotation mark after the end parenthesis is incorrect and changes the meaning of the quote.
Therefore, the best choice is to include a page number in the citation.
