Problem: Kanye West:

West demonstrated an affinity for the arts at an early age; he began writing poetry when he was five years old. His mother recalled that she first took notice of West's passion for drawing and music when he was in the third grade. Growing up in the city,[which?] West became deeply involved in its hip hop scene. He started rapping in the third grade and began making musical compositions in the seventh grade, eventually selling them to other artists. At age thirteen, West wrote a rap song called "Green Eggs and Ham" and began to persuade his mother to pay $25 an hour for time in a recording studio. It was a small, crude basement studio where a microphone hung from the ceiling by a wire clothes hanger. Although this wasn't what West's mother wanted, she nonetheless supported him. West crossed paths with producer/DJ No I.D., with whom he quickly formed a close friendship. No I.D. soon became West's mentor, and it was from him that West learned how to sample and program beats after he received his first sampler at age 15.

What was the name of the producer that helped Kanye West?

A: No I.D.

Problem: Elizabeth and Philip were married on 20 November 1947 at Westminster Abbey. They received 2500 wedding gifts from around the world. Because Britain had not yet completely recovered from the devastation of the war, Elizabeth required ration coupons to buy the material for her gown, which was designed by Norman Hartnell. In post-war Britain, it was not acceptable for the Duke of Edinburgh's German relations, including his three surviving sisters, to be invited to the wedding. The Duke of Windsor, formerly King Edward VIII, was not invited either.
How many sisters did Philip have in all?

The fact that Somali legal terminology is practically devoid of loan words from foreign languages suggests that Xeer is truly indigenous.
In what century did the Xeer system begin?
A: 7th

Question: Liberia has the highest ratio of foreign direct investment to GDP in the world, with US$16 billion in investment since 2006.

Later chapters provide evidence that evolution has occurred, supporting the idea of branching, adaptive evolution without directly proving that selection is the mechanism. Darwin presents supporting facts drawn from many disciplines, showing that his theory could explain a myriad of observations from many fields of natural history that were inexplicable under the alternate concept that species had been individually created. The structure of Darwin's argument showed the influence of John Herschel, whose philosophy of science maintained that a mechanism could be called a vera causa (true cause) if three things could be demonstrated: its existence in nature, its ability to produce the effects of interest, and its ability to explain a wide range of observations.
What does Darwin do to show that his theory can support many theories that could not be explained by individual creation of species?
A:
Darwin presents supporting facts drawn from many disciplines
