Problem: Korean War:

Meanwhile, U.S. garrisons in Japan continually dispatched soldiers and materiel to reinforce defenders in the Pusan Perimeter. Tank battalions deployed to Korea directly from the U.S. mainland from the port of San Francisco to the port of Pusan, the largest Korean port. By late August, the Pusan Perimeter had some 500 medium tanks battle-ready. In early September 1950, ROK Army and UN Command forces outnumbered the KPA 180,000 to 100,000 soldiers. The UN forces, once prepared, counterattacked and broke out of the Pusan Perimeter.

What is Korea's largest port?

A: the port of Pusan

Problem: The persecution reached a peak in Nazi Germany's Final Solution, which led to the Holocaust and the slaughter of approximately 6 million Jews. Of the world's 15 million Jews in 1939, more than a third were killed in the Holocaust. The Holocaustthe state-led systematic persecution and genocide of European Jews (and certain communities of North African Jews in European controlled North Africa) and other minority groups of Europe during World War II by Germany and its collaborators remains the most notable modern-day persecution of Jews. The persecution and genocide were accomplished in stages. Legislation to remove the Jews from civil society was enacted years before the outbreak of World War II. Concentration camps were established in which inmates were used as slave labour until they died of exhaustion or disease. Where the Third Reich conquered new territory in Eastern Europe, specialized units called Einsatzgruppen murdered Jews and political opponents in mass shootings. Jews and Roma were crammed into ghettos before being transported hundreds of miles by freight train to extermination camps where, if they survived the journey, the majority of them were killed in gas chambers. Virtually every arm of Germany's bureaucracy was involved in the logistics of the mass murder, turning the country into what one Holocaust scholar has called "a genocidal nation."

The German Empire had primarily economic interests in Micronesia. The Japanese interests were in land. Despite the Marshalls' small area and few resources, the absorption of the territory by Japan would to some extent alleviate Japan's problem of an increasing population with a diminishing amount of available land to house it. During its years of colonial rule, Japan moved more than 1,000 Japanese to the Marshall Islands although they never outnumbered the indigenous peoples as they did in the Mariana Islands and Palau.
What was the primary nature of Germany's interest in the Marshall Islands?
A: economic

Context and question: Bermuda watercolours painted by local artists are sold at various galleries. Hand-carved cedar sculptures are another speciality. One such 7 ft (2.1 m) sculpture, created by Bermudian sculptor Chesley Trott, is installed at the airport's baggage claim area. In 2010, his sculpture The Arrival was unveiled near the bay to commemorate the freeing of slaves from the American brig Enterprise in 1835. Local artwork may also be viewed at several galleries around the island. Alfred Birdsey was one of the more famous and talented watercolourists; his impressionistic landscapes of Hamilton, St George's and the surrounding sailboats, homes, and bays of Bermuda are world-renowned.
Who created the 7 m sculpture installed at the airport?
Answer: unanswerable

Question: The Greater Richmond area was named the third-best city for business by MarketWatch in September 2007, ranking behind only the Minneapolis and Denver areas and just above Boston. The area is home to six Fortune 500 companies: electric utility Dominion Resources; CarMax; Owens & Minor; Genworth Financial; MeadWestvaco; McKesson Medical-Surgical and Altria Group. However, only Dominion Resources and MeadWestvaco are headquartered within the city of Richmond; the others are located in the neighboring counties of Henrico and Hanover. In 2008, Altria moved its corporate HQ from New York City to Henrico County, adding another Fortune 500 corporation to Richmond's list. In February 2006, MeadWestvaco announced that they would move from Stamford, Connecticut, to Richmond in 2008 with the help of the Greater Richmond Partnership, a regional economic development organization that also helped locate Aditya Birla Minacs, Amazon.com, and Honeywell International, to the region.
Is there an answer to this question: What did MarketWatch think was the fourth best city for business?

The biologist Lynn Margulis, famous for her work on endosymbiosis, contends that symbiosis is a major driving force behind evolution. She considers Darwin's notion of evolution, driven by competition, to be incomplete and claims that evolution is strongly based on co-operation, interaction, and mutual dependence among organisms. According to Margulis and Dorion Sagan, "Life did not take over the globe by combat, but by networking."
What is strongly based only upon uncooperative interaction and independence?
A:
