That depends on the edition you are using.
In "Fahrenheit 451," Clarisse talks about school on page 27 in the part where she discusses her thoughts on education and human interaction with Montag. She describes her school as a place where they learn facts but not necessarily how to reason or think critically.
Montag's neighbor Clarisse McClellan : "Do you ever read any of the books you burn?"
Mildred mentions the White Clown on page 58 of the novel Fahrenheit 451 by Ray Bradbury. She is referring to a character in a television show, which she finds to be very entertaining.
The mention of the phoenix in Ray Bradbury's Fahrenheit 451 can be found on page 163 in most editions of the book. The phoenix is a symbolic part of Montag's realization and represents rebirth and renewal.
In Fahrenheit 451, Montag talks about the woman burned in the fire on page 36 of the book. This is during a conversation with his wife, Mildred, where he is reflecting on the incident that deeply impacted him.
In Ray Bradbury's Fahrenheit 451, Mildred talks about running over dogs and squirrels on page 84 of the novel. In this scene, she nonchalantly mentions this in conversation with Montag, reflecting a society that has become numb to violence and destruction.
Mildred Montag tries to commit suicide by means of overdose on page 13 of Fahrenheit 451. This is the page where Montag finds her and figures out what happened. The whole regenerating of Mildred and other important factors in the book carry on until page 16. On the bottom of page 18, Montag tries to talk to Mildred about her attempted suicide, with no success. Hope this was moderately helpful. :)
Introducing Clarisse first helps to establish a contrast between her curious and free-spirited nature with Montag's more conformist and numb existence with Mildred. This strategic introduction allows Bradbury to highlight the stark differences in character, setting the stage for Montag's transformation as he interacts more with Clarisse.
Clarisse talks to Montag about a dandelion. She shows Montag how to rub the flower under his chin to see if he is in love. This conversation sparks Montag's curiosity and begins his journey to question the society in which he lives.
