Problem: Cotton:

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).

From what source was raw cotton first bought and later resold?
---
A: colonial markets


Problem: According to the Office for National Statistics, at the 2001 census there were over a million black people in the United Kingdom; 1% of the total population described themselves as "Black Caribbean", 0.8% as "Black African", and 0.2% as "Black other". Britain encouraged the immigration of workers from the Caribbean after World War II; the first symbolic movement was those who came on the ship the Empire Windrush. The preferred official umbrella term is "black and minority ethnic" (BME), but sometimes the term "black" is used on its own, to express unified opposition to racism, as in the Southall Black Sisters, which started with a mainly British Asian constituency, and the National Black Police Association, which has a membership of "African, African-Caribbean and Asian origin".
What percentage of the population was "Black Caribbean"?
---
Answer: 1%


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The climate in the state depends mainly in the elevation of the terrain. According to Köppen climate classification the state has five major climate zones. The Sierra Madre Occidental dominates the western part of the state; there are two main climates in this area: Subtropical Highland (Cfb) and Humid Subtropical (Cwa). There are some microclimates in the state due to the varying topology mostly found in the western side of the state. The two best known microclimates are: Tropical savanna climate (Aw) in deep canyons located in the extreme southern part of the state; Continental Mediterranean climate (Dsb) in the extremely high elevations of the Sierra Madre Occidental. Satellite image to the right shows the vegetation is much greener in the west because of the cooler temperatures and larger amounts of precipitation as compared to the rest of the state.
Climate in the state depends mainly on what?
A: elevation of the terrain


Context and question: South Raleigh is located along U.S. 401 south toward Fuquay-Varina and along US 70 into suburban Garner. This area is the least developed and least dense area of Raleigh (much of the area lies within the Swift Creek watershed district, where development regulations limit housing densities and construction). The area is bordered to the west by Cary, to the east by Garner, and to the southwest by Holly Springs. Neighborhoods in South Raleigh include Renaissance Park, Lake Wheeler, Swift Creek, Carolina Pines, Rhamkatte, Riverbrooke, and Enchanted Oaks.
Where is North Raleigh?

Question: The city also has several major surface arteries. U.S. Route 1 (Columbus Avenue, Union Avenue, Water Street, Forbes Avenue) runs in an east-west direction south of downtown serving Union Station and leading out of the city to Milford, West Haven, East Haven and Branford. The main road from downtown heading northwest is Whalley Avenue (partly signed as Route 10 and Route 63) leading to Westville and Woodbridge. Heading north towards Hamden, there are two major thoroughfares, Dixwell Avenue and Whitney Avenue. To the northeast are Middletown Avenue (Route 17), which leads to the Montowese section of North Haven, and Foxon Boulevard (Route 80), which leads to the Foxon section of East Haven and to the town of North Branford. To the west is Route 34, which leads to the city of Derby. Other major intracity arteries are Ella Grasso Boulevard (Route 10) west of downtown, and College Street, Temple Street, Church Street, Elm Street, and Grove Street in the downtown area.
Is there an answer to this question: What is the name of the route that heads north of downtown?

The Queen surpassed her great-great-grandmother, Queen Victoria, to become the longest-lived British monarch in December 2007, and the longest-reigning British monarch on 9 September 2015. She was celebrated in Canada as the "longest-reigning sovereign in Canada's modern era". (King Louis XIV of France reigned over part of Canada for longer.) She is the longest-reigning queen regnant in history, the world's oldest reigning monarch and second-longest-serving current head of state after King Bhumibol Adulyadej of Thailand.
