Problem: In the early 20th century Valencia was an industrialised city. The silk industry had disappeared, but there was a large production of hides and skins, wood, metals and foodstuffs, this last with substantial exports, particularly of wine and citrus. Small businesses predominated, but with the rapid mechanisation of industry larger companies were being formed. The best expression of this dynamic was in the regional exhibitions, including that of 1909 held next to the pedestrian avenue L'Albereda (Paseo de la Alameda), which depicted the progress of agriculture and industry. Among the most architecturally successful buildings of the era were those designed in the Art Nouveau style, such as the North Station (Gare du Nord) and the Central and Columbus markets.
When was an exhibition held that showed agricultural and industrial progress?

Answer: 1909

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 1874 general election, Disraeli was returned to power. He passed the Public Worship Regulation Act 1874, which removed Catholic rituals from the Anglican liturgy and which Victoria strongly supported. She preferred short, simple services, and personally considered herself more aligned with the presbyterian Church of Scotland than the episcopal Church of England. He also pushed the Royal Titles Act 1876 through Parliament, so that Victoria took the title "Empress of India" from 1 May 1876. The new title was proclaimed at the Delhi Durbar of 1 January 1877.
Where did Victoria really align herself when it came to religion?
A: presbyterian Church of Scotland

Context and question: The South Saharan steppe and woodlands ecoregion is a narrow band running east and west between the hyper-arid Sahara and the Sahel savannas to the south. Movements of the equatorial Intertropical Convergence Zone (ITCZ) bring summer rains during July and August which average 100 to 200 mm (3.9 to 7.9 in) but vary greatly from year to year. These rains sustain summer pastures of grasses and herbs, with dry woodlands and shrublands along seasonal watercourses. This ecoregion covers 1,101,700 km2 (425,400 mi2) in Algeria, Chad, Mali, Mauritania, and Sudan.
Where does it not rain in July and August?
Answer: unanswerable

Question: Conventionally, Iranian languages are grouped in "western" and "eastern" branches. These terms have little meaning with respect to Old Avestan as that stage of the language may predate the settling of the Iranian peoples into western and eastern groups. The geographic terms also have little meaning when applied to Younger Avestan since it isn't known where that dialect (or dialects) was spoken either. Certain is only that Avestan (all forms) and Old Persian are distinct, and since Old Persian is "western", and Avestan was not Old Persian, Avestan acquired a default assignment to "eastern". Confusing the issue is the introduction of a western Iranian substrate in later Avestan compositions and redactions undertaken at the centers of imperial power in western Iran (either in the south-west in Persia, or in the north-west in Nisa/Parthia and Ecbatana/Media).
Is there an answer to this question: What language is associated with the Eastern branch of Avestan?

Answer: unanswerable

QUES: A month after having decreed the reform, the pope with a brief of 3 April 1582 granted to Antonio Lilio, the brother of Luigi Lilio, the exclusive right to publish the calendar for a period of ten years. The Lunario Novo secondo la nuova riforma printed by Vincenzo Accolti, one of the first calendars printed in Rome after the reform, notes at the bottom that it was signed with papal authorization and by Lilio (Con licentia delli Superiori... et permissu Ant(onii) Lilij). The papal brief was later revoked, on 20 September 1582, because Antonio Lilio proved unable to keep up with the demand for copies.

What problem caused the papal brief granting the right to publish to be withdrawn?
What is the answer?
ANS:
demand for copies
