Task: Question Generation
Input (English): Passage: On 13 June walruses attacked and damaged the kayaks, causing another stop for repairs. On 17 June, as they prepared to leave again, Nansen thought he heard a dog bark and went to investigate. He then heard voices, and a few minutes later encountered a human being. It was Frederick Jackson, who had organised his own expedition to Franz Josef Land after being rejected by Nansen, and had based his headquarters at Cape Flora on Northbrook Island, the southernmost island of the archipelago. Jackson's own account records that his first reaction to this sudden meeting was to assume the figure to be a shipwrecked sailor, perhaps from the expedition's supply ship Windward which was due to call that summer. As he approached, Jackson saw "a tall man, wearing a soft felt hat, loosely made, voluminous clothes and long shaggy hair and beard, all reeking with black grease". After a moment's awkward hesitation, Jackson recognised his visitor: "You are Nansen, aren't you?", and received the reply "Yes, I am Nansen."Johansen was rescued, and the pair taken to the base at Cape Flora, where they posed for photographs (in one instance re-enacting the Jackson–Nansen meeting) before taking baths and haircuts. Both men seemed in good health, despite their ordeal; Nansen had put on 21 pounds (9.5 kg) in weight since the start of the expedition, and Johansen 13 pounds (5.9 kg). In honour of his rescuer, Nansen named the island where he had wintered "Frederick Jackson Island". For the next six weeks Nansen had little to do but await the arrival of Windward, worrying that he might have to spend the winter at Cape Flora, and sometimes regretting that he and Johansen had not pressed on to Spitsbergen. Johansen noted in his journal that Nansen had changed from the overbearing personality of the Fram days, and was now subdued and polite, adamant that he would never undertake such a journey again. On 26 July Windward finally arrived; on 7 August, with Nansen and Johansen aboard, she sailed south and on 13 August reached Vardø. A batch of telegrams was sent, informing the world of Nansen's safe return.
Output (English): What is the name of the person that was assumed to be a shipwrecked sailor?
