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.
One example: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.
Solution is here: When was the French and Indian War?
Explanation: This question is based on the following sentence in the passage- The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. It is a common convention to write (start year-end year) beside a historical event to understand when the event happened. You can ask questions like this one about dates, years, other numerals, persons, locations, noun phrases, verb phrases, adjectives, clauses etc. which exist in the paragraph.

Now, solve this: 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 Ibáñez, gained considerably more of the popular vote.
Solution:
In what year did the cantonalist uprising occur?
