Problem: Given the question: Given the following passage "The M. tuberculosis complex (MTBC) includes four other TB-causing mycobacteria: M. bovis, M. africanum, M. canetti, and M. microti. M. africanum is not widespread, but it is a significant cause of tuberculosis in parts of Africa. M. bovis was once a common cause of tuberculosis, but the introduction of pasteurized milk has almost completely eliminated this as a public health problem in developed countries. M. canetti is rare and seems to be limited to the Horn of Africa, although a few cases have been seen in African emigrants. M. microti is also rare and is seen almost only in immunodeficient people, although its prevalence may be significantly underestimated.", answer the following question. Note that the answer is present within the text. Question: Who brought TB-causing mycobacteria to other countries?
++++++++++++++++++++++++++++++++
The answer is:
African emigrants

Problem: Given the question: Given the following passage "To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activityor rather, the circulation of seawater through the enlarged ridgesenriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.", answer the following question. Note that the answer is present within the text. Question: What was in India during the Cretaceous?
++++++++++++++++++++++++++++++++
The answer is:
Deccan Traps were laid down

Problem: Given the question: Given the following passage "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-taishogun, 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.", answer the following question. Note that the answer is present within the text. Question: Which class ruled following the Gempei War?
++++++++++++++++++++++++++++++++
