PROBLEM: Passage: The Slaters of Wolverhampton are plagued with Mrs. Slater's chronic debilitating asthma and her cooking limited to what comes in canned goods that she can heat in boiling water. Mr. Alan Slater is sick with worry and has a cantankerous personality. Nigel longs for a life that is more than a succession of canned-food dinners made from what can be heated in boiling water. When dinner is burnt, the standard substitute of toast is always served. He loves toast, with the crunchy outside giving way to buttery softness inside. Despite her infrequent forays into cooking meals from scratch, his mother's attempts to improve her cooking change nothing before or after her death. His father continues in widowhood with the same cooking style and frequent dinners of toast. The experience brings Nigel to conclude that he is not liked. Nigel learns from a friend that the way in which he could attempt a better relationship with his father is to cook a meal for him.
His cooking efforts are thwarted by the new housekeeper, the married and "common" Mrs. Joan Potter, who seduces Alan with her apple pie and array of gourmet meals. The two start to spend time together: at one point, she exiting her council house through an upstairs window so as not to be found out by her husband. Without announcement, the Slaters move to the Herefordshire countryside along with Mrs. Potter. Nigel co-exists with her but never accepts her. She makes a competition of cooking when the teenaged Nigel's shows an emerging interest in developing his skills at school home economics class cookery lessons. Mrs. Potter's lemon meringue pie becomes Nigel's quest to learn the secret recipe. 
Question: While Nigel's mom has asthma, what makes his dad ill?

SOLUTION: worry.

PROBLEM: Passage: Ferrier gave her first London recital on 28 December 1942 at the National Gallery, in a lunch-time concert organised by Dame Myra Hess. Although she wrote "went off very well" in her diary, Ferrier was disappointed with her performance, and concluded that she needed further voice training. She approached the distinguished baritone Roy Henderson with whom, a week previously, she had sung in Mendelssohn's Elijah. Henderson agreed to teach her, and was her regular voice coach for the remainder of her life. He later explained that her "warm and spacious tone" was in part due to the size of the cavity at the back of her throat: "one could have shot a fair-sized apple right to the back of the throat without obstruction". However, this natural physical advantage was not in itself enough to ensure the quality of her voice; this was due, Henderson says, to "her hard work, artistry, sincerity, personality and above all her character".
Ferrier's performances in the Glyndebourne run, which began on 12 July 1946, earned her favourable reviews, although the opera itself was less well received. On the provincial tour which followed the festival it failed to attract the public and incurred heavy financial losses.
By contrast, when the opera reached Amsterdam it was greeted warmly by the Dutch audiences who showed particular enthusiasm for Ferrier's performance. This was Ferrier's first trip abroad, and she wrote an excited letter to her family: "The cleanest houses and windows you ever did see, and flowers in the fields all the way!" Following her success as Lucretia she agreed to return to Glyndebourne in 1947, to sing Orfeo in Gluck's opera Orfeo ed Euridice. She had often sung Orfeo's aria Che farò ("What is life") as a concert piece, and had recently recorded it with Decca. At Glyndebourne, Ferrier's limited acting abilities caused some difficulties in her relationship with the conductor, Fritz Stiedry; nevertheless her performance on the first night, 19 June 1947, attracted warm critical praise.Ferrier's association with Glyndebourne bore further fruit when Rudolf Bing, the festival's general manager, recommended her to Bruno Walter as the contralto soloist in a performance of Mahler's symphonic song cycle Das Lied von der Erde. This was planned for the 1947 Edinburgh International Festival. Walter was initially wary of working with a relatively new singer, but after her audition his fears were allayed; "I recognised with delight that here potentially was one of the greatest singers of our time", he later wrote. Das Lied von der Erde was at that time largely unknown in Britain, and some critics found it unappealing; nevertheless, the Edinburgh Evening News thought it "simply superb". In a later biographical sketch of Ferrier, Lord Harewood described the partnership between Walter and her, which endured until the singer's final illness, as "a rare match of music, voice and temperament.". 
Question: What is the last name of the person who sang with Roy in Mendelssohn's Elijah?

SOLUTION: Ferrier.

PROBLEM: Passage: Philip Arnold Heseltine (30 October 1894 – 17 December 1930), known by the pseudonym Peter Warlock, was a British composer and music critic. The Warlock name, which reflects Heseltine's interest in occult practices, was used for all his published musical works. He is best known as a composer of songs and other vocal music; he also achieved notoriety in his lifetime through his unconventional and often scandalous lifestyle.
As a schoolboy at Eton College, Heseltine met the British composer Frederick Delius, with whom he formed a close friendship. After a failed student career in Oxford and London, Heseltine turned to musical journalism, while developing interests in folk-song and Elizabethan music. His first serious compositions date from around 1915. Following a period of inactivity, a positive and lasting influence on his work arose from his meeting in 1916 with the Dutch composer Bernard van Dieren; he also gained creative impetus from a year spent in Ireland, studying Celtic culture and language. On his return to England in 1918, Heseltine began composing songs in a distinctive, original style, while building a reputation as a combative and controversial music critic.  During 1920–21 he edited the music magazine The Sackbut. His most prolific period as a composer came in the 1920s, when he was based first in Wales and later at Eynsford in Kent.
Through his critical writings, published under his own name, Heseltine made a pioneering contribution to the scholarship of early music. In addition, he produced a full-length biography of Frederick Delius and wrote, edited, or otherwise assisted the production of several other books and pamphlets. Towards the end of his life, Heseltine became depressed by a loss of his creative inspiration. He died in his London flat of coal gas poisoning in 1930, probably by his own hand. 
Question: What is the first name of the person whose serious compositions date from around 1915?

SOLUTION:
Philip.
