This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Q: During the Cantonal Revolution of 1873, a cantonalist uprising that took place during the First Spanish Republic, the city was consolidated with most of the nearby cities in the Federal Canton of Valencia (proclaimed on 19 July and dissolved on 7 August). It did not have the revolutionary fervor of the movement in cities like Alcoy, as it was initiated by the bourgeoisie, but the Madrid government sent General Martinez-Campos to stifle the rebellion by force of arms and subjected Valencia to an intense bombardment. The city surrendered on 7 August; Alfonso XII was proclaimed king on 29 December 1874, and arrived in Valencia on 11 January 1875 on his way to Madrid, marking the end of the first republic. Despite the Bourbon restoration, the roughly even balance between conservatives and liberals in the government was sustained in Valencia until the granting of universal male suffrage in 1890, after which the Republicans, led by Vicente Blasco Ibanez, gained considerably more of the popular vote.

A: In what year did the cantonalist uprising occur?

Q: Gaddafi's ideological worldview was moulded by his environment, namely his Islamic faith, his Bedouin upbringing, and his disgust at the actions of European colonialists in Libya. He was driven by a sense of "divine mission", believing himself a conduit of Allah's will, and thought that he must achieve his goals "no matter what the cost". Raised within the Sunni branch of Islam, Gaddafi called for the implementation of sharia within Libya. He desired unity across the Islamic world, and encouraged the propagation of the faith elsewhere. On a 2010 visit to Italy, he paid a modelling agency to find 200 young Italian women for a lecture he gave urging them to convert. He also funded the construction and renovation of two mosques in Africa, including Uganda's Kampala Mosque. He nevertheless clashed with conservative Libyan clerics as to his interpretation of Islam. Many criticised his attempts to encourage women to enter traditionally male-only sectors of society, such as the armed forces. Gaddafi was keen to improve women's status, though saw the sexes as "separate but equal" and therefore felt women should usually remain in traditional roles.

A: What variety of Islam was Gaddafi raised in?

Q: Plants synthesize a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibers that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and the C4 carbon fixation pathway for photosynthesis which avoid the losses resulting from photorespiration in the more common C3 carbon fixation pathway. These biochemical strategies are unique to land plants.
