What are the three rules that Ralph tells the boys they have broken, at the meeting?

-Bathroom / lavatory not happening at the rocks.

-no signal fire kept

- No shelters being built

It's difficult to say because there are multiple meetings, but there are certainly three rules that the boys break throughout their time on the island: namely, not to speak without the conch shell (in the meetings, that is), not to stray away from the lagoon (unless with an exploration), and not to disrespect the leader, Ralph.

Hope that helps!

1)a boy can only speak at the meetings if he is holding the conch shell.

2) the fire must be kept burning on the mountain going so that is a plane passes, the boys can be saved.

3) Everyone should help build huts.
