Question: Though much of Enlightenment political thought was dominated by social contract theorists, both David Hume and Adam Ferguson criticized this camp. Hume's essay Of the Original Contract argues that governments derived from consent are rarely seen, and civil government is grounded in a ruler's habitual authority and force. It is precisely because of the ruler's authority over-and-against the subject, that the subject tacitly consents; Hume says that the subjects would "never imagine that their consent made him sovereign", rather the authority did so. Similarly, Ferguson did not believe citizens built the state, rather polities grew out of social development. In his 1767 An Essay on the History of Civil Society, Ferguson uses the four stages of progress, a theory that was very popular in Scotland at the time, to explain how humans advance from a hunting and gathering society to a commercial and civil society without "signing" a social contract.
Try to answer this question if possible: In what work did Ferguson explain how humans advanced from a hunting and gathering society to a commercial and civil society without "signing" a social contract?
Answer: An Essay on the History of Civil Society
Question: The Sustainable Development Goals are ambitious, and they will require enormous efforts across countries, continents, industries and disciplines - but they are achievable. UNFPA is working with governments, partners and other UN agencies to directly tackle many of these goals - in particular Goal 3 on health, Goal 4 on education and Goal 5 on gender equality - and contributes in a variety of ways to achieving many of the rest. 
Try to answer this question if possible: The third of the goals concerns what?
Answer: health
Question: Switzerland has four official languages: principally German (63.5% total population share, with foreign residents, in 2013); French (22.5%) in the west; and Italian (8.1%) in the south. The fourth official language, Romansh (0.5%), is a Romance language spoken locally in the southeastern trilingual canton of Graubünden, and is designated by Article 4 of the Federal Constitution as a national language along with German, French, and Italian, and in Article 70 as an official language if the authorities communicate with persons who speak Romansh. However, federal laws and other official acts do not need to be decreed in Romansh.
Try to answer this question if possible: How many official languages does Switzerland have?
Answer: four
Question: In addition to having evolved, for the most part, separately from one another and with distinct individual histories, the Latin-based regional Romance languages of Italy are also better classified as separate languages rather than true "dialects" due to the often high degree in which they lack mutual intelligibility. Though mostly mutually unintelligible, the exact degree to which the regional Italian languages are mutual unintelligible varies, often correlating with geographical distance or geographical barriers between the languages, with some regional Italian languages that are closer in geographical proximity to each other or closer to each other on the dialect continuum being more or less mutually intelligible. For instance, a speaker of purely Eastern Lombard, a language in Northern Italy's Lombardy region that includes the Bergamasque dialect, would have severely limited mutual intelligibility with a purely standard Italian speaker and would be nearly completely unintelligible to a speaker of a pure Sicilian language variant. Due to Eastern Lombard's status as a Gallo-Italic language, an Eastern Lombard speaker may, in fact, have more mutual intelligibility with a Occitan, Catalan, or French speaker than a standard Italian or Sicilian language speaker. Meanwhile, a Sicilian language speaker would have an greater degree of mutual intelligibility with a speaker of the more closely related Neapolitan language, but far less mutual intelligibility with a person speaking Sicilian Gallo-Italic, a language that developed in isolated Lombard emigrant communities on the same island as the Sicilian language.
