Answer:
The full...thing that Odysseus says is "Dear friends, more than one man, or two, should know this things Circe foresaw for us and shared with me, so let me tell her forecast: then we die with our eyes open, if we are going to die or know what death we baffle if we can"
What this means is Circe helps Odeyssues by telling him about the sirens on how they can lurk the men with their voices and drown them... so when he finds or hears this news he tell his shipmates that Crice foresaw their death...its just that, its quite simple actually...anyway because Circe told Odeyssues about what she forsaw... Odeyssues and his shipmates didn't die on their voyage to the Island Of Sirens.
Hope this was helpfull..... Pls tell me your answer, you know whether it was helpfull or not...
