Example Input: Question: In what country is the publication based that Patrick French writes for? Passage:Jasanoff's 2017 book, The Dawn Watch: Joseph Conrad in a Global World, published by Penguin Press and in the UK by William Collins centers on the life and times of novelist Joseph Conrad. The Times lauded the book as the "Conrad for our time," and The Spectator called her an "enviably gifted writer...her historian's eye can untie knots that might baffle the pure critic," noting that she "steers us securely and stylishly through those latitudes where Conrad witnessed the future scupper the past." In the judgment of the Financial Times: "This is an unobtrusively skilful, subtle, clear-eyed book, beautifully narrated," while the Literary Review observes: "Written with a novelist's flair for vivid detail and a scholar's attention to texts, The Dawn Watch is by any standard a major contribution to our understanding of Conrad and his time." Reviewing the book in The Guardian, Patrick French began: "The Dawn Watch will win prizes, and if it doesn't, there is something wrong with the prizes." In The Hindu, Sudipta Datta wrote that Jasanoff's approach to Conrad makes for a "remarkable retelling of Joseph Conrad's life and work and its resonance with the present dysfunctional world." In The Guardian, William Dalrymple named the book to his list of best holiday reads of 2017. According to the Wall Street Journal's reviewer, "'The Dawn Watch' is the most vivid and suggestive biography of Conrad ever written." In The New York Times, Ngugi wa Thiong'O applauded the book as "masterful." Thiong'O wrote that Jasanoff succeeded where "An Image of Africa: Racism in Joseph Conrad's Heart of Darkness," Chinua Achebe's classic Conrad essay, had failed, specifically in bringing into clear relief "Conrad's ability to capture the hypocrisy of the 'civilizing mission' and the material interests that drove capitalist empires, crushing the human spirit." "'The Dawn Watch,' Thiong'O wrote, "will become a creative companion to all students of his work. It has made me want to re-establish connections with the Conrad whose written sentences once inspired in me the same joy as a musical phrase."

Example Input: Question: Which of the two ships was successfully built first? Passage:He led the 1901-1904 Swedish Antarctic Expedition, aboard the ship Antarctic. The expedition visited the Falkland Islands before the ship, commanded by seasoned Antarctic sailor Carl Anton Larsen, dropped Nordenskjöld's party off at Snow Hill Island, a small island off the coast of the Antarctic Peninsula. Nordenskiöld overwintered at Snow Hill Island, while Antarctic returned to the Falklands. The following summer Larsen brought her south, intending to retrieve the Nordenskiöld party, but she became trapped in ice which eventually crushed her hull, forcing Larsen and his crew to overwinter in a hastily constructed shelter on Paulet Island. Larsen and Nordenskjöld finally rendezvoused at their fall-back rescue hut at Hope Bay in late 1903, where they were picked up by the Argentine Navy corvette ARA Uruguay (commanded by Julián Irízar), which had been dispatched when Antarctic had failed to make her appointed return to South America the previous year. Despite its end and the great hardships endured, the expedition was considered a scientific success, with the parties having explored much of the eastern coast of Graham Land, including Cape Longing, James Ross Island, the Joinville Island group, and the Palmer Archipelago. The expedition, which also recovered valuable geological samples and samples of marine animals, earned Nordenskjöld lasting fame at home, but its huge cost left him greatly in debt.
