question:
Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Petén lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles). 
Question: Who had four iron and two bronze pedreros?
answer:
the Spanish.


question:
Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.". 
Question: What is the last name of the person whose mother gave him piano lessons?
answer:
Wood.


question:
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 first serious compositions date from around 1915?
answer:

Philip.
