Problem: Freemasonry:

Prince Hall Freemasonry exists because of the refusal of early American lodges to admit African-Americans. In 1775, an African-American named Prince Hall, along with fourteen other African-Americans, was initiated into a British military lodge with a warrant from the Grand Lodge of Ireland, having failed to obtain admission from the other lodges in Boston. When the military Lodge left North America, those fifteen men were given the authority to meet as a Lodge, but not to initiate Masons. In 1784, these individuals obtained a Warrant from the Premier Grand Lodge of England (GLE) and formed African Lodge, Number 459. When the UGLE was formed in 1813, all U.S.-based Lodges were stricken from their rolls due largely to the War of 1812. Thus, separated from both UGLE and any concordantly recognised U.S. Grand Lodge, African Lodge re-titled itself as the African Lodge, Number 1 and became a de facto "Grand Lodge" (this Lodge is not to be confused with the various Grand Lodges on the Continent of Africa). As with the rest of U.S. Freemasonry, Prince Hall Freemasonry soon grew and organised on a Grand Lodge system for each state.

The African Lodge re-titled itself what?

A: the African Lodge, Number 1

Problem: The advent of the Industrial Revolution in Britain provided a great boost to cotton manufacture, as textiles emerged as Britain's leading export. In 1738, Lewis Paul and John Wyatt, of Birmingham, England, patented the roller spinning machine, as well as the flyer-and-bobbin system for drawing cotton to a more even thickness using two sets of rollers that traveled at different speeds. Later, the invention of the James Hargreaves' spinning jenny in 1764, Richard Arkwright's spinning frame in 1769 and Samuel Crompton's spinning mule in 1775 enabled British spinners to produce cotton yarn at much higher rates. From the late 18th century on, the British city of Manchester acquired the nickname "Cottonopolis" due to the cotton industry's omnipresence within the city, and Manchester's role as the heart of the global cotton trade.
When was a new spinning machine patented that boosted frame production?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Some species, including frigatebirds, gulls, and skuas, engage in kleptoparasitism, stealing food items from other birds. Kleptoparasitism is thought to be a supplement to food obtained by hunting, rather than a significant part of any species' diet; a study of great frigatebirds stealing from masked boobies estimated that the frigatebirds stole at most 40% of their food and on average stole only 5%. Other birds are scavengers; some of these, like vultures, are specialised carrion eaters, while others, like gulls, corvids, or other birds of prey, are opportunists.
What is kleptoparasitism?
A: stealing food items from other birds

Context and question: From the start of the 20th century through the 1970s, the American tuna fishing fleet and tuna canning industry were based in San Diego, "the tuna capital of the world". San Diego's first tuna cannery was founded in 1911, and by the mid-1930s the canneries employed more than 1,000 people. A large fishing fleet supported the canneries, mostly staffed by immigrant fishermen from Japan, and later from the Portuguese Azores and Italy whose influence is still felt in neighborhoods like Little Italy and Point Loma. Due to rising costs and foreign competition, the last of the canneries closed in the early 1980s.
Why were the canneries ultimately closed by the early 1980s?
Answer: rising costs and foreign competition

A 2000 United States Department of the Treasury study of lending trends for 305 cities from 1993 to 1998 showed that $467 billion of mortgage lending was made by Community Reinvestment Act (CRA)-covered lenders into low and mid level income (LMI) borrowers and neighborhoods, representing 10% of all U.S. mortgage lending during the period. The majority of these were prime loans. Sub-prime loans made by CRA-covered institutions constituted a 3% market share of LMI loans in 1998, but in the run-up to the crisis, fully 25% of all sub-prime lending occurred at CRA-covered institutions and another 25% of sub-prime loans had some connection with CRA. In addition, an analysis by the Federal Reserve Bank of Dallas in 2009, however, concluded that the CRA was not responsible for the mortgage loan crisis, pointing out that CRA rules have been in place since 1995 whereas the poor lending emerged only a decade later. Furthermore, most sub-prime loans were not made to the LMI borrowers targeted by the CRA, especially in the years 20052006 leading up to the crisis. Nor did it find any evidence that lending under the CRA rules increased delinquency rates or that the CRA indirectly influenced independent mortgage lenders to ramp up sub-prime lending.
What percent of sub-prime loans had some connection with CRA in the run-up to the financial crisis?
A:
25%
