Example Input: Tocqueville thought the conquest of Algeria was important for two reasons: first, his understanding of the international situation and France's position in the world, and, second, changes in French society. Tocqueville believed that war and colonization would "restore national pride, threatened", he believed, by "The gradual softening of social mores" in the middle classes. Their taste for "material pleasures" was spreading to the whole of society, giving it "an example of weakness and egotism". Applauding the methods of General Bugeaud, Tocqueville went so far to claim that "war in Africa is a science. Everyone is familiar with its rules and everyone can apply those rules with almost complete certainty of success. One of the greatest services that Field Marshal Bugeaud has rendered his country is to have spread, perfected and made everyone aware of this new science." Tocqueville advocated racial segregation in Algeria with two distinct legislations, one for European colonists and one for the Arab population. Such a two-tier arrangement would be fully realised with the 1870 Cremieux decree and the Indigenousness Code, which extended French citizenship to European settlers and Algerian Jews, whereas Muslim Algerians would be governed by Muslim law and restricted to a second-class citizenship. <sep>What did Tocqueville believe was spreading and which society was it spreading through?<sep>A deadly virus

Example Input:  The little party in the cabin, so disastrously begun, finished, under the mellowing influence of wine and woman, in excellent feeling and with some hilarity.  Mamie, in a plush Gainsborough hat and a gown of wine-coloured silk, sat, an apparent queen, among her rude surroundings and companions.  The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil.  It was the last act of the evening.  Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness.  But it was to Mamie that I devoted the best of my attention; and it was with her I made my chief success. <sep>Was the author usually an admirer of the women in a plush Gainsborough hat and a gown of wine-coloured silk.<sep>No one
Example Output: No

Example Input: Expansion quickly peaked however, and the European powers who had carved up the New World set about testing each other in dynastic conflicts and colonial rivalry. The English were the main rivals of the Dutch on the high seas, and there were several wars between the two in the 17th and 18th centuries. In 1665–1667 the Dutch sailed up the River Medway and sank the British fleet moored there. The 18th century saw Amsterdam grow into the foremost financial center in the world, but the seeds of decline had already been planted. When the English colonies in New England rose up in revolt against the British, they found ready Ailies in the Dutch. From their colonies in the Caribbean they sent caches of arms and ammunition. The British were furious and went to war in 1780, destroying the Dutch navy and signaling a sudden decline in power and influence from which the Netherlands never recovered. Trade suffered to such an extent that in 1791 the VOC went into liquidation. In the latter part of the century there were anti-Orange demonstrations by pro-French factions in the country, and in 1795 Napoleon Bonaparte took the Netherlands in his epic march across Europe. Under the yoke of another foreign power, and with trade at an all time low, the Golden Age was truly dead. The Return of the House of Orange Napoleon installed his brother Louis as King of Holland and he chose to take the fine Town Hall on Dam Square as his palace — now the Koninklijk Palace. But only four years later he fled the city after civil disturbances broke out when he raised taxes. When Napoleon's bubble burst and French power began to wane, William of Orange emerged from exile and was proclaimed king in 1813. Amsterdam had to work its way out of economic decline, but throughout the 19th century the city grew steadily. Industrialization changed the city. With the building of the Central Station at the end of the century, Amsterdam turned its back on its seafaring past and looked towards the mechanical age for its future. The station was built over the old harbor wall and some of the oldest canals in the city center were filled in to allow better access to motorized vehicles. Dam Square was landlocked for the first time in its history. <sep>The building of the Central Station occurred at the end of which century?<sep>19th Century
Example Output:
Yes
