Context and question: The first political factions, cohering around a basic, if fluid, set of principles emerged from the Exclusion Crisis and Glorious Revolution in late-17th-century England. The Whigs supported Protestant constitutional monarchy against absolute rule and the Tories, originating in the Royalist (or "Cavalier") faction of the English Civil War, were conservative royalist supporters of a strong monarchy as a counterbalance to the republican tendencies of Whigs, who were the dominant political faction for most of the first half of the 18th century; they supported the Hanoverian succession of 1715 against the Jacobite supporters of the deposed Roman Catholic Stuart dynasty and were able to purge Tory politicians from important government positions after the failed Jacobite rising of 1715. The leader of the Whigs was Robert Walpole, who maintained control of the government in the period 17211742; his protege was Henry Pelham (17431754).
What groups first formed in 1715 when the Whigs were dominant?
Answer: unanswerable

Question: Domestic geese are much larger than their wild counterparts and tend to have thick necks, an upright posture, and large bodies with broad rear ends. The greylag-derived birds are large and fleshy and used for meat, while the Chinese geese have smaller frames and are mainly used for egg production. The fine down of both is valued for use in pillows and padded garments. They forage on grass and weeds, supplementing this with small invertebrates, and one of the attractions of rearing geese is their ability to grow and thrive on a grass-based system. They are very gregarious and have good memories and can be allowed to roam widely in the knowledge that they will return home by dusk. The Chinese goose is more aggressive and noisy than other geese and can be used as a guard animal to warn of intruders. The flesh of meat geese is dark-coloured and high in protein, but they deposit fat subcutaneously, although this fat contains mostly monounsaturated fatty acids. The birds are killed either around 10 or about 24 weeks. Between these ages, problems with dressing the carcase occur because of the presence of developing pin feathers.
Is there an answer to this question: What is the down feathers of geese never used for?

Answer: unanswerable

Question: All of Britain's campaigns against New France succeeded in 1759, part of what became known as an Annus Mirabilis. Fort Niagara and Fort Carillon on 8 July 1758 fell to sizable British forces, cutting off French frontier forts further west. On 13 September 1759, following a three-month siege of Quebec, General James Wolfe defeated the French on the Plains of Abraham outside the city. The French staged a counteroffensive in the spring of 1760, with initial success at the Battle of Sainte-Foy, but they were unable to retake Quebec, due to British naval superiority following the battle of Neuville. The French forces retreated to Montreal, where on 8 September they surrendered to overwhelming British numerical superiority.
Is there an answer to this question: Did the French take Quebec back?

Answer:
they were unable to retake Quebec
