Answer:
This foreshadows Percy Jackson's connection to Greek mythology.
Step-by-step explanation:
The above excerpt was taken from the book "Parcy Jackson and the lightning thief" and shows the moment when Percy still doesn't know that he is Posseidon's son and is living like an ordinary boy attending a Greek mythology class, which seems uninteresting to all the students. Like Percy, the reader is still unaware of his connection to Greek mythology, but the girls' speech in the text foreshadows this news that is revealed a few minutes later.
