Task: Question Generation
Input (English): Passage: The Hut Point and Cape Evans huts remain, protected by the Antarctic Heritage Trust and the New Zealand government. Within the Cape Evans hut an inscription by Richards on the wall near his bunk, listing the names of those lost, can still be read, but the generally deteriorating condition of the huts has caused concern.The Aurora survived for less than a year after her final return from the Ross Sea. Shackleton had sold her for £10,000, and her new role was as a coal-carrier between Australia and South America.  She disappeared in the Pacific Ocean, on or about 2 January 1918, having either foundered in a storm or been sunk by an enemy raider.  Aboard her was James Paton of the Ross Sea ship's party, who was still serving as her boatswain. Ernest Wild was also a victim of the First World War.  He died of typhoid in Malta, on 10 March 1918, while serving with the Royal Navy in the Mediterranean.On 4 July 1923, Joyce and Richards were awarded Albert Medals by George V for their bravery and life-saving efforts during the second depot-laying journey.  Wild and Victor Hayward received the same award, posthumously. Many of the survivors enjoyed long and successful careers.  The young wireless operator, Lionel Hooke, joined Amalgamated Wireless Australasia Ltd and was responsible for many technological innovations.  He became the company's managing director in 1945 and its chairman in 1962, having been knighted for services to industry in 1957. Of the four dogs who survived the trek, Con was killed by the other dogs in a fight before the rescue. The others, Oscar, Gunner and Towser, returned in the ship to New Zealand and were placed in Wellington Zoo, where Oscar lived, allegedly, to the age of 25. Near the end of his life Dick Richards, the last survivor of the party, was without regrets and did not regard the struggle as futile.  Rather, he believed, it was something that the human spirit had accomplished, and that no undertaking carried through to conclusion was for nothing.
Output (English): What are the specific names of the four dogs who survived the trek?
