Problem: Kievan Rus%27:

The last ruler to maintain united state was Mstislav the Great. After his death in 1132 the Kievan Rus' fell into recession and a rapid decline, and Mstislav's successor Yaropolk II of Kiev instead of focussing on the external threat of the Cumans was embroiled in conflicts with the growing power of the Novgorod Republic. In 1169, as the Kievan Rus' state was full of internal conflict, Andrei Bogolyubsky of Vladimir sacked the city of Kiev. The sack of the city fundamentally changed the perception of Kiev and was evidence of the fragmentation of the Kievan Rus'. By the end of the 12th century, the Kievan state became even further fragmented and had been divided into roughly twelve different principalities.

Problem: The band, now revitalised by the response to Live Aid a "shot in the arm" Roger Taylor called it, and the ensuing increase in record sales, ended 1985 by releasing the single "One Vision", which was the third time after "Stone Cold Crazy" and "Under Pressure (with David Bowie)" that all four bandmembers received a writing credit for the one song. Also, a limited-edition boxed set containing all Queen albums to date was released under the title of The Complete Works. The package included previously unreleased material, most notably Queen's non-album single of Christmas 1984, titled "Thank God It's Christmas".

Gautama was now determined to complete his spiritual quest. At the age of 35, he famously sat in meditation under a Ficus religiosa tree now called the Bodhi Tree in the town of Bodh Gaya and vowed not to rise before achieving enlightenment. After many days, he finally destroyed the fetters of his mind, thereby liberating himself from the cycle of suffering and rebirth, and arose as a fully enlightened being (Skt. samyaksambuddha). Soon thereafter, he attracted a band of followers and instituted a monastic order. Now, as the Buddha, he spent the rest of his life teaching the path of awakening he had discovered, traveling throughout the northeastern part of the Indian subcontinent, and died at the age of 80 (483 BCE) in Kushinagar, India. The south branch of the original fig tree available only in Anuradhapura Sri Lanka is known as Jaya Sri Maha Bodhi.
At what age did Gautama come to pass?
A: 80

Context and question: Production capacity in Britain and the United States was improved by the invention of the cotton gin by the American Eli Whitney in 1793. Before the development of cotton gins, the cotton fibers had to be pulled from the seeds tediously by hand. By the late 1700s a number of crude ginning machines had been developed. However, to produce a bale of cotton required over 600 hours of human labor, making large-scale production uneconomical in the United States, even with the use of humans as slave labor. The gin that Whitney manufactured (the Holmes design) reduced the hours down to just a dozen or so per bale. Although Whitney patented his own design for a cotton gin, he manufactured a prior design from Henry Odgen Holmes, for which Holmes filed a patent in 1796. Improving technology and increasing control of world markets allowed British traders to develop a commercial chain in which raw cotton fibers were (at first) purchased from colonial plantations, processed into cotton cloth in the mills of Lancashire, and then exported on British ships to captive colonial markets in West Africa, India, and China (via Shanghai and Hong Kong).
What business development did the Americans use to establish a hold on the global cotton market?
