Problem: During the American occupation of the state, the number of Indian attacks was drastically reduced, but in 1848 the attacks resumed to such a degree that the Mexican officials had no choice but to resume military projects to protect Mexican settlements in the state. Through the next three decades the state faced constant attacks from indigenous on Mexican settlements. After the occupation the people of the state were worried about the potential attack from the hostile indigenous tribes north of the Rio Grande; as a result a decree on July 19, 1848, the state established 18 military colonies along the Rio Grande. The new military colonies were to replace the presidios as population centers to prevent future invasions by indigenous tribes; these policies remained prominent in the state until 1883. Eventually the state replaced the old state security with a state policy to form militias organized with every Mexican in the state capable to serve between the ages of 18 and 55 to fulfill the mandate of having six men defending for every 1000 residents.
What group continuously attacked Mexican settlements?
The answer is the following: indigenous tribes

Problem: The Human Development Index report of 2005 shows that there were three boroughs with a very high Human Development Index, 12 with a high HDI value (9 above .85) and one with a medium HDI value (almost high). Benito Juarez borough had the highest HDI of the country (.9510) followed by Miguel Hidalgo which came up 4th nationally with a HDI of (.9189) and Coyoacan (5th nationally) with a HDI value of (.9169). Cuajimalpa, Cuauhtemoc and Azcapotzalco had very high values; respectively .8994 (15th nationally),.8922 (23rd) and .8915 (25th).
How many boroughs had high (not very high) HDI scores?
The answer is the following: 12

Problem: In 1980, Rhodesia, Britain's last African colony, became the independent nation of Zimbabwe. The New Hebrides achieved independence (as Vanuatu) in 1980, with Belize following suit in 1981. The passage of the British Nationality Act 1981, which reclassified the remaining Crown colonies as "British Dependent Territories" (renamed British Overseas Territories in 2002) meant that, aside from a scattering of islands and outposts the process of decolonisation that had begun after the Second World War was largely complete. In 1982, Britain's resolve in defending its remaining overseas territories was tested when Argentina invaded the Falkland Islands, acting on a long-standing claim that dated back to the Spanish Empire. Britain's ultimately successful military response to retake the islands during the ensuing Falklands War was viewed by many to have contributed to reversing the downward trend in Britain's status as a world power. The same year, the Canadian government severed its last legal link with Britain by patriating the Canadian constitution from Britain. The 1982 Canada Act passed by the British parliament ended the need for British involvement in changes to the Canadian constitution. Similarly, the Constitution Act 1986 reformed the constitution of New Zealand to sever its constitutional link with Britain, and the Australia Act 1986 severed the constitutional link between Britain and the Australian states. In 1984, Brunei, Britain's last remaining Asian protectorate, gained its independence.
Which 1980s war victory helped Britain seem more like a world power again?
The answer is the following: Falklands War

Problem: Immigration of Czechs from Europe to the United States occurred primarily from 1848 to 1914. Czech is a Less Commonly Taught Language in U.S. schools, and is taught at Czech heritage centers. Large communities of Czech Americans live in the states of Texas, Nebraska and Wisconsin. In the 2000 United States Census, Czech was reported as the most-common language spoken at home (besides English) in Valley, Butler and Saunders Counties, Nebraska and Republic County, Kansas. With the exception of Spanish (the non-English language most commonly spoken at home nationwide), Czech was the most-common home language in over a dozen additional counties in Nebraska, Kansas, Texas, North Dakota and Minnesota. As of 2009, 70,500 Americans spoke Czech as their first language (49th place nationwide, behind Turkish and ahead of Swedish).
What is the most commonly spoken non-English language at homes nationwide in the U.S.?
The answer is the following:
Spanish
