Task: Question Generation
Input (English): Passage: With her scholarship funds exhausted, Holst needed a job, and in June 1931 took charge of music at the Citizen House arts and education centre in Bath.  She disliked the disciplines imposed by an unsympathetic and unyielding superior, but stayed until the end of the year, by which time Citizen House had relocated to Hampstead.    She worked briefly as a freelance conductor and accompanist before joining the staff of the EFDS early in 1932. The organisation had by now expanded to become the "English Folk Dance and Song Society" (EFDSS) and was based in new headquarters at Cecil Sharp House. The duties, mainly teaching, were not full-time, and she was able to take up part-time teaching posts at her old school, Eothen, and at Roedean School.  Although she composed little original music during these years, she made many instrumental and vocal arrangements of traditional folk melodies.Gustav Holst's health had been poor for years; in the winter of 1933–34 it deteriorated, and he died on 25 May 1934. Imogen Holst privately determined that she would establish and protect her father's musical legacy. On 24 March 1935 she took part in a Gustav Holst memorial concert, in which she conducted her own arrangement of one of her father's brass band suites.  Meanwhile, her own music was beginning to attract attention. Her carol arrangement "Nowell and Nowell" was performed in a 1934 Christmas concert in Chichester Cathedral, and the following year saw the premiere of her Concerto for Violin and Strings, with Elsie Avril as the soloist.  In 1936 she paid a visit to Hollywood, where she stayed with her uncle (Gustav's brother), the actor Ernest Cossart.  Back in England, Holst worked on recorder arrangements of music by the neglected 16th-century composer Pelham Humphrey. These were published in 1936 to a positive critical reception.In 1938 Holst published a biography of her father.  Among many positive comments from friends and critics, the composer Edmund Rubbra praised her for producing a book that was not "clouded by sentiment ... her biography is at once intimate and objective".
Output (English): What is the full name of the person who made many instrumental and vocal arrangements of traditional folk melodies during the years she was holding several part-time teaching posts?
