Task: Question Generation
Input (English):  Tancred, Lord Montacute, the novel's idealistic young hero, seems destined to live the life of any conventional member of the British ruling class. Dissatisfied with his life in fashionable London circles, he instead leaves his parents and retraces the steps of his Crusader ancestors to the Holy Land, hoping there to "penetrate the great Asian mystery"  and understand the roots of Christianity. He meets the beautiful Eva, daughter of a Jewish financier, and becomes involved in the political machinations of her foster-brother, the brilliant Fakredeen, a Lebanese emir. At Fakredeen's instigation Tancred is kidnapped and held captive, but is nevertheless allowed to visit Mount Sinai. Here he has a vision of an angel who tells him he must be the prophet of "the sublime and solacing doctrine of theocratic equality", a concept which Disraeli leaves somewhat hazy. Tancred falls ill, and is released at the instigation of Eva, who nurses him back to health. She teaches him about the glories of Mediterranean civilization and the debt that Christianity owes to Judaism. Tancred, in love with Eva and utterly convinced that she is right, proposes marriage, but the romance is broken off when his parents appear to reclaim their son and take him back to England.
Output (English): Where does Tancred have a vision of an Angel?
