Problem: Frederic Chopin:

Frederic Francois Chopin (/opn/; French pronunciation: [fe.de.ik f.swa .p]; 22 February or 1 March 1810 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.

Problem: The drunkenness and lawlessness created by gin was seen to lead to ruination and degradation of the working classes. The distinction[clarification needed] was illustrated by William Hogarth in his engravings Beer Street and Gin Lane. The Gin Act 1736 imposed high taxes on retailers and led to riots in the streets. The prohibitive duty was gradually reduced and finally abolished in 1742. The Gin Act 1751 however was more successful. It forced distillers to sell only to licensed retailers and brought gin shops under the jurisdiction of local magistrates.
What artist created the engraving Beer Street and Gin Lane?

Various owners leased it from royal landlords and the freehold was the subject of frenzied speculation during the 17th century. By then, the old village of Eye Cross had long since fallen into decay, and the area was mostly wasteland. Needing money, James I sold off part of the Crown freehold but retained part of the site on which he established a 4-acre (16,000 m2) mulberry garden for the production of silk. (This is at the northwest corner of today's palace.) Clement Walker in Anarchia Anglicana (1649) refers to "new-erected sodoms and spintries at the Mulberry Garden at S. James's"; this suggests it may have been a place of debauchery. Eventually, in the late 17th century, the freehold was inherited from the property tycoon Sir Hugh Audley by the great heiress Mary Davies.
Who suggests that the mulberry garden is likely a place for debauchery?
A: Clement Walker

Context and question: Calcutta (now Kolkata) was the capital of India during the British Raj until December 1911. However, Delhi had served as the political and financial centre of several empires of ancient India and the Delhi Sultanate, most notably of the Mughal Empire from 1649 to 1857. During the early 1900s, a proposal was made to the British administration to shift the capital of the British Indian Empire (as it was officially called) from Calcutta to Delhi. Unlike Calcutta, which was located on the eastern coast of India, Delhi was at the centre of northern India and the Government of British India felt that it would be logistically easier to administer India from the latter rather than the former.
What is the name of the city formerly known as Calcutta?
Answer: Kolkata

Question: In the year 712, Muhammad bin Qasim, an Umayyad general, sailed from the Persian Gulf into Sindh in Pakistan and conquered both the Sindh and the Punjab regions along the Indus river. The conquest of Sindh and Punjab, in modern-day Pakistan, although costly, were major gains for the Umayyad Caliphate. However, further gains were halted by Hindu kingdoms in India in the battle of Rajasthan. The Arabs tried to invade India but they were defeated by the north Indian king Nagabhata of the Pratihara Dynasty and by the south Indian Emperor Vikramaditya II of the Chalukya dynasty in the early 8th century. After this the Arab chroniclers admit that the Caliph Mahdi "gave up the project of conquering any part of India."
Is there an answer to this question: Who stopped India from invading the Arabs?

Answer: unanswerable

In parliamentary systems, governments are generally required to have the confidence of the lower house of parliament (though a small minority of parliaments, by giving a right to block supply to upper houses, in effect make the cabinet responsible to both houses, though in reality upper houses, even when they have the power, rarely exercise it). Where they lose a vote of confidence, have a motion of no confidence passed against them, or where they lose supply, most constitutional systems require either:
