Task: Question Answering
Input (English): Minerva and Telemaco return to Ithaca in a chariot. Telemaco is greeted joyfully by Eumete and the disguised Ulisse in the woodland grove: "O great son of Ulysses, you have indeed returned!" After Eumete goes to inform Penelope of Telemaco's arrival a bolt of fire descends on Ulisse, removing his disguise and revealing his true identity to his son. The two celebrate their reunion before Ulisse sends Telemaco to the palace, promising to follow shortly. In the palace, Melanto complains to Eurimaco that Penelope still refuses to choose a suitor: "In short, Eurymachus, the lady has a heart of stone." Soon afterwards Penelope receives the three suitors (Antinoo, Pisandro, Anfinomo), and rejects each in turn despite their efforts to enliven the court with singing and dancing: "Now to enjoyment, to dance and song!" After the suitors' departure Eumete tells Penelope that Telemaco has arrived in Ithaca, but she is doubtful: "Such uncertain things redouble my grief." Eumete's message is overheard by the suitors, who plot to kill Telemaco. However, they are unnerved when a symbolic eagle flies overhead, so they abandon their plan and renew their efforts to capture Penelope's heart, this time with gold. Back in the woodland grove, Minerva tells Ulisse that she has organised a means whereby he will be able to challenge and destroy the suitors. Resuming his beggar's disguise, Ulisse arrives at the palace, where he is challenged to a fight by Iro, ("I will pluck out the hairs of your beard one by one!"), a challenge he accepts and wins. Penelope now states that she will accept the suitor who is able to string Ulisse's bow. All three suitors attempt the task unsuccessfully. The disguised Ulisse then asks to try though renouncing the prize of Penelope's hand, and to everyone's amazement he succeeds. He then angrily denounces the suitors and, summoning the names of the gods, kills all three with the bow: "This is how the bow wounds! To death, to havoc, to ruin!"
Output (English): Which person was said to have a heart of stone?
