Input: Article: In simple terms the structure of the Alps consists of layers of rock of European, African and oceanic (Tethyan) origin. The bottom nappe structure is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of great folding. The tip of the mountain consists of gneisses from the African plate; the base of the peak, below the glaciated area, consists of European basement rock. The sequence of Tethyan marine sediments and their oceanic basement is sandwiched between rock derived from the African and European plates.

Now answer this question: Layers of rock from Europe, Africa and the ocean make up what?

Output: the structure of the Alps


Article: During the First World War, Paris sometimes found itself on the front line; 600 to 1,000 Paris taxis played a small but highly important symbolic role in transporting 6,000 soldiers to the front line at the First Battle of the Marne.

Here is a question about this article: The city has started moving away from the automobile and towards mass transit. From 2004 to 2009, the annual number of unlinked public transportation trips increased by approximately 21%. In 2006, voters in King County passed proposition 2 (Transit Now) which increased bus service hours on high ridership routes and paid for five bus rapid transit lines called RapidRide. After rejecting a roads and transit measure in 2007, Seattle-area voters passed a transit only measure in 2008 to increase ST Express bus service, extend the Link Light Rail system, and expand and improve Sounder commuter rail service. A light rail line from downtown heading south to Sea-Tac Airport began service on December 19, 2009, giving the city its first rapid transit line with intermediate stations within the city limits. An extension north to the University of Washington is scheduled to open in 2016; and further extensions are planned to reach Lynnwood to the north, Des Moines to the south, and Bellevue and Redmond to the east by 2023. Former mayor Michael McGinn has supported building light rail from downtown to Ballard and West Seattle.
What is the answer to this question: Which former mayor backed the expansion of rail lines from downtown to Ballard?
****
So... Michael McGinn

Problem: Please answer a question about the following article about Detroit:
Detroit, like many places in the United States, developed racial conflict and discrimination in the 20th century following rapid demographic changes as hundreds of thousands of new workers were attracted to the industrial city; in a short period it became the 4th-largest city in the nation. The Great Migration brought rural blacks from the South; they were outnumbered by southern whites who also migrated to the city. Immigration brought southern and eastern Europeans of Catholic and Jewish faith; these new groups competed with native-born whites for jobs and housing in the booming city. Detroit was one of the major Midwest cities that was a site for the dramatic urban revival of the Ku Klux Klan beginning in 1915. "By the 1920s the city had become a stronghold of the KKK," whose members opposed Catholic and Jewish immigrants, as well as black Americans. The Black Legion, a secret vigilante group, was active in the Detroit area in the 1930s, when one-third of its estimated 20,000 to 30,000 members in Michigan were based in the city. It was defeated after numerous prosecutions following the kidnapping and murder in 1936 of Charles Poole, a Catholic Works Progress Administration organizer. A total of 49 men of the Black Legion were convicted of numerous crimes, with many sentenced to life in prison for murder.
What is the name of the movement of rural blacks in the early 20th century called?
A: The Great Migration


Question: Read this and answer the question

The Swazi economy is very closely linked to the economy of South Africa, from which it receives over 90% of its imports and to which it sends about 70% of its exports. Swaziland's other key trading partners are the United States and the EU, from whom the country has received trade preferences for apparel exports (under the African Growth and Opportunity Act – AGOA – to the US) and for sugar (to the EU).

Textile exports grew by over 200% between 2000 and 2005 and sugar exports increasing by more than 50% over the same period.

What percentage of exported goods from Swaziland end up in South Africa?
Answer:
70%
