Question: Passage: Bartlett decided to send a team back to establish the exact location of the island that the Anderson party had approached, and to determine if Anderson had actually landed there. An injury to his knee ruled Mamen out from this mission, which was undertaken by ship's steward Ernest Chafe, with the Inuit pair, Kataktovik and Kuraluk. Chafe's group came within 2 miles (3 km) of Herald Island before being stopped by open water. A careful examination through binoculars revealed no signs of the missing party, and Chafe concluded that Anderson and company had not reached the island. Chafe and his party then returned to Shipwreck Camp.Meanwhile, on 4 February, Mackay and his group (Murray and Beuchat, joined by seaman Stanley Morris) announced they were leaving the next day, to seek land. Mackay presented Bartlett with a letter dated 1 February that began: "We, the undersigned, in consideration of the present critical situation, desire to make an attempt to reach the land." The letter requested appropriate supplies, and concluded by emphasising that the journey was on their own initiative and absolving Bartlett from all responsibilities. Bartlett allocated them a sledge, a tent, six gallons of oil, a rifle and ammunition and food for 50 days. They left on 5 February; the last sighting of them was a few days later, by Chafe and the Inuit, returning from their abortive trip to Herald Island. They found Mackay's party struggling to make headway, with some of their provisions lost and clothing and other equipment discarded to lighten their load. Beuchat in particular was in a distressed state, nearly delirious and in the throes of hypothermia. However, the party refused assistance and rejected Chafe's pleas that they return with him to Shipwreck Camp. Thereafter the only hint of their fate was a sailor's scarf belonging to Morris, later found buried in an ice floe. It was assumed that the four had either been crushed by the ice, or had fallen through it. 
Question: What were the last names of the people in Mackay's group?

Answer: Murray.


Question: Passage: In 1964 Shostakovich composed the music for the Russian film Hamlet, which was favourably reviewed by The New York Times: "But the lack of this aural stimulation – of Shakespeare's eloquent words – is recompensed in some measure by a splendid and stirring musical score by Dmitri Shostakovich. This has great dignity and depth, and at times an appropriate wildness or becoming levity".In later life, Shostakovich suffered from chronic ill health, but he resisted giving up cigarettes and vodka. Beginning in 1958 he suffered from a debilitating condition that particularly affected his right hand, eventually forcing him to give up piano playing; in 1965 it was diagnosed as poliomyelitis. He also suffered heart attacks the following year and again in 1971, and several falls in which he broke both his legs; in 1967 he wrote in a letter: "Target achieved so far: 75% (right leg broken, left leg broken, right hand defective). All I need to do now is wreck the left hand and then 100% of my extremities will be out of order."A preoccupation with his own mortality permeates Shostakovich's later works, among them the later quartets and the Fourteenth Symphony of 1969 (a song cycle based on a number of poems on the theme of death). This piece also finds Shostakovich at his most extreme with musical language, with twelve-tone themes and dense polyphony throughout. He dedicated the piece to his close friend Benjamin Britten, who conducted its Western premiere at the 1970 Aldeburgh Festival. The Fifteenth Symphony of 1971 is, by contrast, melodic and retrospective in nature, quoting Wagner, Rossini and the composer's own Fourth Symphony.
Shostakovich died of lung cancer on 9 August 1975. A civic funeral was held; he was interred in Novodevichy Cemetery, Moscow. Even before his death he had been commemorated with the naming of the Shostakovich Peninsula on Alexander Island, Antarctica., Despite suffering from Motor Neurone Disease (or ALS) from as early as the 1960s, Shostakovich insisted upon writing all his own correspondence and music himself, even when his right hand was virtually unusable. This is a last hallmark of his extraordinarily determined and tenacious character.
He was survived by his third wife, Irina; his daughter, Galina; and his son, Maxim, a pianist and conductor who was the dedicatee and first performer of some of his father's works. Shostakovich himself left behind several recordings of his own piano works; other noted interpreters of his music include Emil Gilels, Mstislav Rostropovich, Tatiana Nikolayeva, Maria Yudina, David Oistrakh, and members of the Beethoven Quartet.
His last work was his Viola Sonata, which was first performed on 28 December 1975, four months after his death. 
Question: What is the last name of the person who was eventually forced to give up piano playing due to the debilitating condition that particularly affected his right hand?

Answer:
Shostakovich.
