Task: Question Answering
Input (English): Passage: After the war and following several earlier miscarriages, Irina gave birth to their daughter, Mary Moore, in March 1946. The child was named after Moore's mother, who had died two years earlier. Both the loss of his mother and the arrival of a baby focused Moore's mind on the family, which he expressed in his work by producing many "mother-and-child" compositions, although reclining and internal/external figures also remained popular. In the same year, Moore made his first visit to America when a retrospective exhibition of his work opened at the Museum of Modern Art in New York City.Before the war, Moore had been approached by educator Henry Morris, who was trying to reform education with his concept of the Village College. Morris had engaged Walter Gropius as the architect for his second village college at Impington near Cambridge, and he wanted Moore to design a major public sculpture for the site. The County Council, however, could not afford Gropius's full design, and scaled back the project when Gropius emigrated to America. Lacking funds, Morris had to cancel Moore's sculpture, which had not progressed beyond the maquette stage.  Moore was able to reuse the design in 1950 for a similar commission outside a secondary school for the new town of Stevenage. This time, the project was completed and Family Group became Moore's first large-scale public bronze.In the 1950s, Moore began to receive increasingly significant commissions.  He exhibited Reclining Figure: Festival at the Festival of Britain in 1951, and in 1958 produced a large marble reclining figure for the UNESCO building in Paris.  With many more public works of art, the scale of Moore's sculptures grew significantly and he started to employ an increasing number of assistants to work with him at Much Hadham, including Anthony Caro and Richard Wentworth.On the campus of the University of Chicago in December 1967, 25 years to the minute after the team of physicists led by Enrico Fermi achieved the first controlled, self-sustaining nuclear chain reaction, Moore's Nuclear Energy was unveiled on the site of what was once the university's football field stands, in the rackets court beneath which the experiments had taken place. This 12-foot-tall piece in the middle of a large, open plaza is often thought to represent a mushroom cloud topped by a massive human skull, but Moore's interpretation was very different. He once told a friend that he hoped viewers would "go around it, looking out through the open spaces, and that they may have a feeling of being in a cathedral."  In Chicago, Illinois, Moore also commemorated science with a large bronze sundial, locally named Man Enters the Cosmos (1980), which was commissioned to recognise the space exploration program. 
Question: What was the first name of Moore's mother?
Output (English): Mary.
