Problem: Frédéric Chopin:

Chopin seldom performed publicly in Paris. In later years he generally gave a single annual concert at the Salle Pleyel, a venue that seated three hundred. He played more frequently at salons, but preferred playing at his own Paris apartment for small groups of friends. The musicologist Arthur Hedley has observed that "As a pianist Chopin was unique in acquiring a reputation of the highest order on the basis of a minimum of public appearances—few more than thirty in the course of his lifetime." The list of musicians who took part in some of his concerts provides an indication of the richness of Parisian artistic life during this period. Examples include a concert on 23 March 1833, in which Chopin, Liszt and Hiller performed (on pianos) a concerto by J.S. Bach for three keyboards; and, on 3 March 1838, a concert in which Chopin, his pupil Adolphe Gutmann, Charles-Valentin Alkan, and Alkan's teacher Joseph Zimmermann performed Alkan's arrangement, for eight hands, of two movements from Beethoven's 7th symphony. Chopin was also involved in the composition of Liszt's Hexameron; he wrote the sixth (and final) variation on Bellini's theme. Chopin's music soon found success with publishers, and in 1833 he contracted with Maurice Schlesinger, who arranged for it to be published not only in France but, through his family connections, also in Germany and England.

Problem: Average annual precipitation is 15 inches (380 mm), but great variations are seen. The mountain ranges block the moist Pacific air, holding moisture in the western valleys, and creating rain shadows to the east. Heron, in the west, receives the most precipitation, 34.70 inches (881 mm). On the eastern (leeward) side of a mountain range, the valleys are much drier; Lonepine averages 11.45 inches (291 mm), and Deer Lodge 11.00 inches (279 mm) of precipitation. The mountains themselves can receive over 100 inches (2,500 mm), for example the Grinnell Glacier in Glacier National Park gets 105 inches (2,700 mm). An area southwest of Belfry averaged only 6.59 inches (167 mm) over a sixteen-year period. Most of the larger cities get 30 to 50 inches or 0.76 to 1.27 metres of snow each year. Mountain ranges themselves can accumulate 300 inches or 7.62 metres of snow during a winter. Heavy snowstorms may occur any time from September through May, though most snow falls from November to March.

Answer: 34.70 inches

Question: The Serbo-Croatian dialects differ not only in the question word they are named after, but also heavily in phonology, accentuation and intonation, case endings and tense system (morphology) and basic vocabulary. In the past, Chakavian and Kajkavian dialects were spoken on a much larger territory, but have been replaced by Štokavian during the period of migrations caused by Ottoman Turkish conquest of the Balkans in the 15th and the 16th centuries. These migrations caused the koinéisation of the Shtokavian dialects, that used to form the West Shtokavian (more closer and transitional towards the neighbouring Chakavian and Kajkavian dialects) and East Shtokavian (transitional towards the Torlakian and the whole Bulgaro-Macedonian area) dialect bundles, and their subsequent spread at the expense of Chakavian and Kajkavian. As a result, Štokavian now covers an area larger than all the other dialects combined, and continues to make its progress in the enclaves where non-literary dialects are still being spoken.
Is there an answer to this question: What is morphology to a language?

Answer: tense system
