The problem: Answer a question about this article:
In the colonial years, while conditions were more fluid, white women, indentured servant or free, and African men, servant, slave or free, made unions. Because the women were free, their mixed-race children were born free; they and their descendants formed most of the families of free people of color during the colonial period in Virginia. The scholar Paul Heinegg found that eighty percent of the free people of color in North Carolina in censuses from 1790–1810 could be traced to families free in Virginia in colonial years.
What censuses did he study?
****
The answer: from 1790–1810


The problem: Answer a question about this article:
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.
What types of geese are used for human consumption?
****
The answer: The greylag-derived birds


The problem: Answer a question about this article:
Once known as "the Gibraltar of the West" and "Fortress Bermuda", Bermuda today is defended by forces of the British government. For the first two centuries of settlement, the most potent armed force operating from Bermuda was its merchant shipping fleet, which turned to privateering at every opportunity. The Bermuda government maintained a local militia. After the American Revolutionary War, Bermuda was established as the Western Atlantic headquarters of the Royal Navy. Once the Royal Navy established a base and dockyard defended by regular soldiers, however, the militias were disbanded following the War of 1812. At the end of the 19th century, the colony raised volunteer units to form a reserve for the military garrison.
How did the colony form a military garrison in the 19th century?
****
The answer: raised volunteer units to form a reserve
