Please answer this: A friend asked me to answer this question: Who worked on The Planets during the war?, using the article: At the outbreak of the First World War, Holst tried to enlist but was rejected as unfit for military service. He felt frustrated that he could not contribute to the war effort. His wife became a volunteer ambulance driver; Vaughan Williams went on active service to France as did Holst's brother Emil; Holst's friends the composers George Butterworth and Cecil Coles were killed in battle. He continued to teach and compose; he worked on The Planets and prepared his chamber opera Savitri for performance. It was first given in December 1916 by students of the London School of Opera at the Wellington Hall in St John's Wood. It attracted no attention at the time from the main newspapers, though when professionally staged five years later it was greeted as "a perfect little masterpiece." In 1917 he wrote The Hymn of Jesus for chorus and orchestra, a work which remained unperformed until after the war.In 1918, as the war neared its end, Holst finally had the prospect of a job that offered him the chance to serve. The music section of the YMCA's education department needed volunteers to work with British troops stationed in Europe awaiting demobilisation. Morley College and St Paul's Girls' School offered him a year's leave of absence, but there remained one obstacle: the YMCA felt that his surname looked too German to be acceptable in such a role. He formally changed "von Holst" to "Holst" by deed poll in September 1918. He was appointed as the YMCA's musical organiser for the Near East, based in Salonica., what would be the answer ?

Answer: Holst
Problem: A friend asked me to answer this question: What rapidly started expanding towards the northeast on July 20?, using the article: Almost 250 different fires started in Yellowstone and the surrounding National Forests between June and August. Seven of them were responsible for 95% of the total burned area. At the end of July, the National Park Service and other agencies had fully mobilized available personnel, and yet the fires continued to expand. Smaller fires burned into each other, propelled by dry storms which brought howling winds and dry lightning strikes but no rain. On August 20, the single worst day of the fires and later dubbed "Black Saturday", more than 150,000 acres (610 km2) were consumed during one of many intense fires. Ash from the fires throughout the park drifted as far away as Billings, Montana, 60 miles (97 km) to the northeast. The wind driven flames jumped roads and firelines, and burning embers started new fires a mile (1.6 km) or more ahead of the main fires. Ground fires raced the fuel ladder to the forest canopy and became crown fires with flames over 200 feet (61 m) high. On that single day, more Yellowstone land burned than in all other fires combined since the establishment of the park. Throughout the summer, fires made huge advances of 5 to 10 miles (8.0 to 16.1 km) a day, and there were even occasions when more than 2 miles (3.2 km) in one hour were recorded.One large group of fires was known as the Snake River Complex. These fires were in the southern section of the park, in the headwaters region of the Yellowstone and Snake Rivers. The largest fire in the group was the Shoshone fire which was started by lightning on June 23. The prescribed natural burn policy was still in effect, and at first no efforts were made to suppress this fire. It smoldered with little movement for several weeks, then rapidly started expanding towards the northeast on July 20.The Red fire started near Lewis Lake on July 1, and like the Shoshone fire, advanced little for several weeks. The fire then moved northeast on July 19, and combined with the Shoshone fire in August. As these two fires advanced towards the Grant Village..., what would be the answer ?

A: Shoshone fire
Q: A friend asked me to answer this question: What is the last name of the person who we know was commissioned around 1442 by the Cologne council to provide decorations for the visit of Emperor Frederick III?, using the article: Stefan Lochner (the Dombild Master or Master Stefan; c. 1410 late 1451) was a German painter working in the late "soft style" of the International Gothic. His paintings combine that era's tendency toward long flowing lines and brilliant colours with the realism, virtuoso surface textures and innovative iconography of the early Northern Renaissance. Based in Cologne, a commercial and artistic hub of northern Europe, Lochner was one of the most important German painters before Albrecht Durer. Extant works include single-panel oil paintings, devotional polyptychs and illuminated manuscripts, which often feature fanciful and blue-winged angels. Today some thirty-seven individual panels are attributed to him with confidence. Less is known of his life. Art historians associating the Dombild Master with the historical Stefan Lochner believe he was born in Meersburg in south-west Germany around 1410, and that he spent some of his apprenticeship in the Low Countries. Records further indicate that his career developed quickly but was cut short by an early death. We know that he was commissioned around 1442 by the Cologne council to provide decorations for the visit of Emperor Frederick III, a major occasion for the city. Records from the following years indicate growing wealth and the purchase of a number of properties around the city. Thereafter he seems to have over-extended his finances and fallen into debt. Plague hit Cologne in 1451 and there, apart from the records of creditors, mention of Stephan Lochner ends; it is presumed he died that year, aged around 40. Lochner's identity and reputation were lost until a revival of 15th-century art during the early 19th-century romantic period. Despite extensive historical research, attribution remains difficult; for centuries a number of associated works were grouped and loosely attributed to the Dombild Master, a notname taken from the Dombild Altarpiece (in English cathedral picture, also known as the Altarpiece of the City's Patron Saints) still in Cologne Cathedral...., what would be the answer ?
A:
Lochner
