<span>In this sentence, the words "to sleep" are an D. infinitive phrase. This is because the words start with an infinitive to sleep, which takes the form of to + verb. It isn't an adjective, but a verb, so it cannot be a predicate adjective. It is a direct object, not an indirect one. It isn't a prepositional phrase, because it doesn't start with a preposition.</span>
For a parenthetical citation using the MLA citation standards for the book Annabelle Plante, Dancing Alone, p. 87, the proper citation would be the following:
(Plante 87)
An example: On the other hand, it can be argued that "QUOTE" (Plante 87)
The parenthetical citation or in-text citation in the MLA format follows the author-page standard; it requires both the author's last name and the page number.
Remember that if the sentence already contains the author's name, the in-text citation should contain only the page number. An example:
Annabelle Plante believes that "QUOTE" (87)
