When was the country where the groups not from the United States originated from in The Sing-Off annexed by the United States?
1898
Title: History of Puerto Rico
Passage: In 1898, during the Spanish -- American War, Puerto Rico was invaded and subsequently became a possession of the United States. The first years of the 20th century were marked by the struggle to obtain greater democratic rights from the United States. The Foraker Act of 1900, which established a civil government, and the Jones Act of 1917, which made Puerto Ricans U.S. citizens, paved the way for the drafting of Puerto Rico's Constitution and its approval by Congress and Puerto Rican voters in 1952. However, the political status of Puerto Rico, a Commonwealth controlled by the United States, remains an anomaly.
Title: Eight Mile, Alabama
Passage: Eight Mile is an unincorporated community in Mobile County, Alabama, United States. The community is named for its distance from the city of Mobile. Part of it was annexed in the mid-20th century by the city of Prichard, Alabama.
Title: A cappella
Passage: Increased interest in modern a cappella (particularly collegiate a cappella) can be seen in the growth of awards such as the Contemporary A Cappella Recording Awards (overseen by the Contemporary A Cappella Society) and competitions such as the International Championship of Collegiate A Cappella for college groups and the Harmony Sweepstakes for all groups. In December 2009, a new television competition series called The Sing-Off aired on NBC. The show featured eight a cappella groups from the United States and Puerto Rico vying for the prize of $100,000 and a recording contract with Epic Records/Sony Music. The show was judged by Ben Folds, Shawn Stockman, and Nicole Scherzinger and was won by an all-male group from Puerto Rico called Nota. The show returned for a second and third season, won by Committed and Pentatonix, respectively.
Title: Eschscholzia ramosa
Passage: The plant is endemic to the Channel Islands of California off the Southern California coast (United States), and to Guadalupe Island off the western coast of Baja California state (Mexico).
Title: Group of Eight
Passage: The forum originated with a 1975 summit hosted by France that brought together representatives of six governments: France, Germany, Italy, Japan, the United Kingdom, and the United States, thus leading to the name Group of Six or G6. The summit came to be known as the Group of Seven, or G7, in 1976 with the addition of Canada. Russia was added to the political forum from 1997, which the following year became known as the G8. In March 2014 Russia was suspended following the annexation of Crimea, whereupon the group's name reverted to the G7. Certain representatives of G7 countries stated that they would be interested in Russia's return to the group. However, in 2017 Russia announced that it would permanently leave the political forum G8. The European Union was represented at the G8 since the 1980s as a ``nonenumerated ''participant, but originally could not host or chair summits. The 40th summit was the first time the European Union was able to host and chair a summit. Collectively, in 2012 the G8 nations comprised 50.1 percent of 2012 global nominal GDP and 40.9 percent of global GDP (PPP).
Title: Mexican–American War
Passage: The Mexican -- American War, also known as the Mexican War and in Mexico the American intervention in Mexico, was an armed conflict between the United States of America and the United Mexican States (Mexico) from 1846 to 1848. It followed in the wake of the 1845 American annexation of the independent Republic of Texas, which Mexico still considered its northeastern province and a part of its territory after its de facto secession in the 1836 Texas Revolution a decade earlier.
Title: Highgrove, California
Passage: Highgrove is a census-designated place (CDP) in Riverside County, California, United States. The population was 3,988 at the 2010 census, up from 3,445 at the 2000 census. The City of Riverside has plans to annex Highgrove.
Title: Tristan da Cunha
Passage: In 1816, the United Kingdom annexed the islands, ruling them from the Cape Colony in South Africa. This is reported to have primarily been a measure to ensure that the French would be unable to use the islands as a base for a rescue operation to free Napoleon Bonaparte from his prison on Saint Helena. The occupation also prevented the United States from using Tristan da Cunha as a cruiser base, as it had during the War of 1812.
