Task: Question Generation
Input (English): Passage: In Hobart, Amundsen received congratulatory telegrams from, among others, former U.S. President Theodore Roosevelt and King George V of the United Kingdom. The king expressed particular pleasure that Amundsen's first port of call on his return had been on soil of the British Empire. In Norway, which only six years earlier had become an independent country after 500 years of Danish and Swedish supremacy, the news was proclaimed in banner headlines, and the national flag was flown throughout the country.  All the expedition's participants received the Norwegian South Pole medal (Sydpolsmedaljen), established by King Haakon to commemorate the expedition.  However, Amundsen's biographer Roland Huntford refers to "the chill underneath the cheers"; there remained a residue of unease over Amundsen's tactics. One Norwegian newspaper expressed relief that Amundsen had found a new route, and had not intruded on Scott's path from McMurdo Sound.In Britain, press reaction to Amundsen's victory was restrained but generally positive. Apart from the enthusiastic reports in the Daily Chronicle and the Illustrated London News—which each had a financial stake in Amundsen's success—the Manchester Guardian remarked that any cause for reproach was wiped out by the Norwegians' courage and determination. Readers of Young England were exhorted not to grudge "the brave Norseman" the honour he had earned, and The Boy's Own Paper suggested that every British boy should read Amundsen's expedition account. The Times correspondent offered a mild rebuke to Amundsen for his failure to inform Scott until it was too late for the latter to respond, "all the more unnecessary, for no one would have welcomed co-operation in the work of South Polar exploration more than Captain Scott ... Still, no one who knows Captain Amundsen can have any doubt of his integrity, and since he states he has reached the Pole we are bound to believe him".Senior figures at the RGS expressed more hostile sentiments, at least privately. To them, Amundsen's feat was the result of "a dirty trick". Markham hinted that Amundsen's claim might be fraudulent: "We must wait for the truth until the return of the Terra Nova". When later in 1912 Amundsen addressed the RGS he felt slighted after Lord Curzon, the Society's president, jocularly called for "three cheers for the dogs". Shackleton did not join in denigrating Amundsen's victory, and called him "perhaps the greatest polar explorer of today". Before she heard the news of her husband's death, Kathleen Scott conceded that Amundsen's journey "was a very fine feat ... in spite of one's irritation one has to admire it".
Output (English): What are the initials of the organization that had senior figures who were hostile to the explorer's feat?
