Question: The ancient-Chamorro society had four classes: chamorri (chiefs), matua (upper class), achaot (middle class), and mana'chang (lower class).:2021 The matua were located in the coastal villages, which meant they had the best access to fishing grounds, whereas the mana'chang were located in the interior of the island. Matua and mana'chang rarely communicated with each other, and matua often used achaot as intermediaries. There were also "makahna" (similar to shamans), skilled in healing and medicine. Belief in spirits of ancient Chamorros called "Taotao mo'na" still persists as a remnant of pre-European culture. Their society was organized along matrilineal clans.:21
Try to answer this question if possible: Where were the matua located on the island?
Answer: coastal villages
Question: Though known since antiquity the commercial growing of cotton in Egypt only started in 1820's, following a Frenchman, by the name of M. Jumel, propositioning the then ruler, Mohamed Ali Pasha, that he could earn a substantial income by growing an extra-long staple Maho (Barbadence) cotton, in Lower Egypt, for the French market. Mohamed Ali Pasha accepted the proposition and granted himself the monopoly on the sale and export of cotton in Egypt; and later dictated cotton should be grown in preference to other crops. By the time of the American Civil war annual exports had reached $16 million (120,000 bales), which rose to $56 million by 1864, primarily due to the loss of the Confederate supply on the world market. Exports continued to grow even after the reintroduction of US cotton, produced now by a paid workforce, and Egyptian exports reached 1.2 million bales a year by 1903.
Try to answer this question if possible: When did cotton begin to be commercially grown in the US?
Answer: unanswerable
Question: In the next two years, the company established its first factory in south India in the town of Machilipatnam on the Coromandel Coast of the Bay of Bengal. The high profits reported by the company after landing in India initially prompted King James I to grant subsidiary licences to other trading companies in England. But in 1609 he renewed the charter given to the company for an indefinite period, including a clause that specified that the charter would cease to be in force if the trade turned unprofitable for three consecutive years.
Try to answer this question if possible: Where was the first factory in south India?
Answer: Machilipatnam
Question: Many contemporary uses of uranium exploit its unique nuclear properties. Uranium-235 has the distinction of being the only naturally occurring fissile isotope. Uranium-238 is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239 in a nuclear reactor. Another fissile isotope, uranium-233, can be produced from natural thorium and is also important in nuclear technology. While uranium-238 has a small probability for spontaneous fission or even induced fission with fast neutrons, uranium-235 and to a lesser degree uranium-233 have a much higher fission cross-section for slow neutrons. In sufficient concentration, these isotopes maintain a sustained nuclear chain reaction. This generates the heat in nuclear power reactors, and produces the fissile material for nuclear weapons. Depleted uranium (238U) is used in kinetic energy penetrators and armor plating.
Try to answer this question if possible: What is the sole fissile isotope that occurs in nature?
Answer:
Uranium-235
