How does the author use foreshadowing in Arcadia?

When Thomasina’s lessons are interrupted by her search for another type of
knowledge, another theme of the play is created. The characters of the play are
constantly distracted from intellectual and scientific pursuits by emotional, relational, or personal complications. Sex plays a large part in these distractions and this moment of distraction for Thomasina foreshadows Chloe’s conclusion about the progress of the universe at a later time in the play.
