Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: When did the war end that brought the inhabitants of New Mexico under the governance of the United States? Passage:Hispanos identify strongly with their Spanish heritage and most are also mestizos of mixed Apache, Comanche, Pueblo, Navajo, Native Mexican, and Genízaro ancestry. Exact numbers for the population size of New Mexican Hispanos is difficult, as many also identify with Chicano and Mexican-American movements. For most of its modern history, New Mexico existed on the periphery of the Spanish empire from 1598 until 1821 and later Mexico (1821–1848), but was dominated by Comancheria politically and economically from the 1750s to 1850s. Due to the Comanche, contact with the rest of Spanish America was limited, and New Mexican Spanish developed closer trading links with the Comanche than the rest of New Spain. In the meantime, some Spanish colonists coexisted with and intermarried with Puebloan peoples and Navajos, enemies of the Comanche. New Mexicans of all ethnicities were commonly enslaved by the Comanche and Apache of Apacheria, while Native New Mexicans were commonly enslaved and adopted Spanish language and culture. These Genízaros served as house servants, sheep herders, and in other capacities in New Mexico including what is known today as Southern Colorado well into the 1800s. By the late 18th century, Genízaros and their descendants, often referred to as Coyotes, comprised nearly one-third of the entire population of New Mexico. After the Mexican–American War, New Mexico and all its inhabitants came under the governance of the English-speaking United States, and for the next hundred years, English-speakers increased in number. By the 1980s, more and more Hispanos were using English instead of New Mexican Spanish at home.

Question: How many rulers did the Bagration's have in total? Passage:The Bagration family's genealogy traces back at least to the medieval era in its male line and hundreds of years further back as rulers in the female line. Leonida's grandfather, Prince Alexander Bagration of Mukhrani, was born in 1853 in Georgia's historical capital Tbilisi, then part of the Russian Empire, and was killed by Bolsheviks at Pyatigorsk in 1918 during the Russian revolution. Fearing for their lives, the family took refuge in Constantinople, then spent eight months in Germany before returning to Tbilisi, now capital of the Georgian Soviet Socialist Republic, to re-claim a portion of property which, as émigrés they risked losing to total confiscation. Although the family made repairs to their home and Leonida would recall her grandfather's insistence that they continue to dine formally on silver plate to retain their sense of propriety, they were eventually deprived of all but two rooms of their old palace and subjected to harassment. Thanks to the intervention of Maxim Gorky, who had enjoyed the patronage of the Bagrations, in 1931 they once again fled the Soviet Union, going into exile in Spain. The family moved to France, where Leonida's grandmother and relations had already settled.
