The detail that best supports the prediction that Penelope will discover the stranger's true identity is "he may have heard/rumors about Odysseus".
This excerpt has been taken from Odyssey, a poem by Homer. In Odyssey, Odysseus disguises himself as a beggar in order to surprise the suitors with Athena's help. He reveals his identity to his son Telemachus and asks him to help to kill the suitors; however, when Penelope finds out that the beggar is his husband Odysseus, she pretends that does not know this in order to protect him.
