Problem: The Taira and the Minamoto clashed again in 1180, beginning the Gempei War, which ended in 1185. Samurai fought at the naval battle of Dan-no-ura, at the Shimonoseki Strait which separates Honshu and Kyushu in 1185. The victorious Minamoto no Yoritomo established the superiority of the samurai over the aristocracy. In 1190 he visited Kyoto and in 1192 became Sei'i-taishōgun, establishing the Kamakura Shogunate, or Kamakura Bakufu. Instead of ruling from Kyoto, he set up the Shogunate in Kamakura, near his base of power. "Bakufu" means "tent government", taken from the encampments the soldiers would live in, in accordance with the Bakufu's status as a military government.
When did the Gempei War begin?

In the shrinking PC industry, Dell continued to lose market share, as it dropped below Lenovo in 2011 to fall to number three in the world. Dell and fellow American contemporary Hewlett Packard came under pressure from Asian PC manufacturers Lenovo, Asus, and Acer, all of which had lower production costs and willing to accept lower profit margins. In addition, while the Asian PC vendors had been improving their quality and design, for instance Lenovo's ThinkPad series was winning corporate customers away from Dell's laptops, Dell's customer service and reputation had been slipping. Dell remained the second-most profitable PC vendor, as it took 13 percent of operating profits in the PC industry during Q4 2012, behind Apple Inc.'s Macintosh that took 45 percent, seven percent at Hewlett Packard, six percent at Lenovo and Asus, and one percent for Acer.
What other American company fell behind Lenovo with Dell?
A: Hewlett Packard


Context and question: Others have argued that excessive regulation suppresses therapeutic innovation, and that the current cost of regulator-required clinical trials prevents the full exploitation of new genetic and biological knowledge for the treatment of human disease. A 2012 report by the President's Council of Advisors on Science and Technology made several key recommendations to reduce regulatory burdens to new drug development, including 1) expanding the FDA's use of accelerated approval processes, 2) creating an expedited approval pathway for drugs intended for use in narrowly defined populations, and 3) undertaking pilot projects designed to evaluate the feasibility of a new, adaptive drug approval process.
What can be used to evaluate new human diseases?
Answer: unanswerable


Question: The mandolin's popularity in the United States was spurred by the success of a group of touring young European musicians known as the Estudiantina Figaro, or in the United States, simply the "Spanish Students." The group landed in the U.S. on January 2, 1880 in New York City, and played in Boston and New York to wildly enthusiastic crowds. Ironically, this ensemble did not play mandolins but rather bandurrias, which are also small, double-strung instruments that resemble the mandolin. The success of the Figaro Spanish Students spawned other groups who imitated their musical style and costumes. An Italian musician, Carlo Curti, hastily started a musical ensemble after seeing the Figaro Spanish Students perform; his group of Italian born Americans called themselves the "Original Spanish Students," counting on the American public to not know the difference between the Spanish bandurrias and Italian mandolins. The imitators' use of mandolins helped to generate enormous public interest in an instrument previously relatively unknown in the United States.
Is there an answer to this question: What did the Origianl Spanish Students expect the African public not to know?

Answer: unanswerable


By the end of the Mesozoic era, the Appalachian Mountains had been eroded to an almost flat plain. It was not until the region was uplifted during the Cenozoic Era that the distinctive topography of the present formed. Uplift rejuvenated the streams, which rapidly responded by cutting downward into the ancient bedrock. Some streams flowed along weak layers that define the folds and faults created many millions of years earlier. Other streams downcut so rapidly that they cut right across the resistant folded rocks of the mountain core, carving canyons across rock layers and geologic structures.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did erosion create in the Cenozoic era?
Ah, so..
