Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: The retreat to London marked the beginning of a tragic period. Rix's mother Elizabeth had been unwell, and deteriorated during the crossing from France to England. Elizabeth was transferred to hospital when they landed; though she partially recovered and was moved to a nursing home, at that same time her other daughter, Elsie, fell ill.Rix shuttled back and forth between her two ailing family members until, on 2 September 1914, Elsie died. For three months Rix withheld the news from her mother, fearing it would harm her already fragile condition. Elizabeth survived the news, but as the war continued, Rix's artistic output dwindled almost to nothing. Then in March 1916, Elizabeth died. Rix was just over thirty years old, and all her immediate relatives were now dead. Recalling the experience, she later wrote: "I could scarcely put one foot in front of the other and walked like an old thing".Further misfortune lay in store. In France, an Australian officer, Captain George Matson Nicholas, was posted to  Étaples. There he heard about the Australian woman artist who had had to leave her paintings behind when she and her family left abruptly for England. Nicholas sought out the works and admired them, and decided to contact the artist when next he was on leave. He met Rix in September 1916, and they were married on 7 October at St Saviour's, Warwick Avenue in London. After three days together, he returned to duty; she was widowed five weeks later on 14 November, when he was shot and killed during battle at Flers, on the Western Front. Initially writing in her diary that she had lost the will to live, Rix Nicholas's grief eventually found its expression in three paintings, titled And Those Who Would Have Been Their Sons, They Gave Their Immortality (a phrase from a poem by Rupert Brooke), Desolation and Pro Humanitate. The second of these paintings (which was destroyed in 1930), portrayed a gaunt and tearful woman shrouded in a black cloak, crouched staring at the viewer amidst a battlescarred landscape, featureless but for the crosses on distant graves. The National Gallery of Australia holds a charcoal drawing made as a study for the work. The first was "a portrait of a woman cradling a ghostly child", while the third represented the tragedy of her short marriage to Nicholas. In visualising the ruin of war, her works were more personal than those of other artists of the last years of World War I, such as Paul Nash and Eric Kennington, and her representation of widowhood was both unusual for its time, and confronting for the viewer.
Output:
What is the name of the painting that portrayed a gaunt and tearful woman shrouded in a black cloak?
