Problem: Background: The overseas expansion under the crown of Castile was initiated under the royal authority and first accomplished by the Spanish conquistadores. The Americas were incorporated into the Spanish Empire, with the exception of Brazil and Canada, and the crown created civil and religious structures to administer the region. The motivations for colonial expansion were trade and the spread of the Catholic faith through indigenous conversions. Beginning with the 1492 arrival of Christopher Columbus in the Caribbean and continuing control of vast territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America (including present day Mexico, Florida and the Southwestern and Pacific Coastal regions of the United States).
Context: During the Napoleonic Peninsular War in Europe between France and Spain, assemblies called juntas were established to rule in the name of Ferdinand VII of Spain. The Libertadores (Spanish and Portuguese for "Liberators") were the principal leaders of the Spanish American wars of independence. They were predominantly criollos (Americas-born people of European ancestry, mostly Spanish or Portuguese), bourgeois and influenced by liberalism and in some cases with military training in the mother country.  In 1809 the first declarations of independence from Spanish rule occurred in the Viceroyalty of New Granada. The first two were in present-day Bolivia at Sucre (May 25), and La Paz (July 16); and the third in present-day Ecuador at Quito (August 10). In 1810 Mexico declared independence, with the Mexican War of Independence following for over a decade. In 1821 Treaty of Cordoba established Mexican independence from Spain and concluded the War. The Plan of Iguala was part of the peace treaty to establish a constitutional foundation for an independent Mexico.  These began a movement for colonial independence that spread to Spain's other colonies in the Americas. The ideas from the French and the American Revolution influenced the efforts. All of the colonies, except Cuba and Puerto Rico, attained independence by the 1820s. The British Empire offered support, wanting to end the Spanish monopoly on trade with its colonies in the Americas.  In 1898, the United States achieved victory in the Spanish-American War with Spain, ending the Spanish colonial era. Spanish possession and rule of its remaining colonies in the Americas ended in that year with its sovereignty transferred to the United States. The United States took occupation of Cuba, the Philippines, and Puerto Rico. Puerto Rico continues to be a possession of the United States, now officially continues as a self-governing unincorporated territory.

Problem: Background: Walter Leland Cronkite Jr. (November 4, 1916 - July 17, 2009) was an American broadcast journalist who served as anchorman for the CBS Evening News for 19 years (1962-1981). During the heyday of CBS News in the 1960s and 1970s, he was often cited as "the most trusted man in America" after being so named in an opinion poll. He reported many events from 1937 to 1981, including bombings in World War II; the Nuremberg trials; combat in the Vietnam War; the Dawson's Field hijackings; Watergate; the Iran Hostage Crisis; and the assassinations of President John F. Kennedy, civil rights pioneer Martin Luther King Jr., and Beatles musician John Lennon. He was also known for his extensive coverage of the U.S. space program, from Project Mercury to the Moon landings to the Space Shuttle.
Context: On April 16, 1962, Cronkite succeeded Douglas Edwards as anchorman of the CBS's nightly feature newscast, tentatively renamed Walter Cronkite with the News, but later the CBS Evening News on September 2, 1963, when the show was expanded from 15 to 30 minutes, making Cronkite the anchor of American network television's first nightly half-hour news program. Cronkite's tenure as anchor of the CBS Evening News made him an icon in television news.  During the early part of his tenure anchoring the CBS Evening News, Cronkite competed against NBC's anchor team of Chet Huntley and David Brinkley, who anchored the Huntley-Brinkley Report. For much of the 1960s, the Huntley-Brinkley Report had more viewers than Cronkite's broadcast. A key moment for Cronkite came during his coverage of John F. Kennedy's assassination on November 22, 1963. Another factor in Cronkite and CBS' ascendancy to the top of the ratings was that, as the decade progressed, RCA made a corporate decision not to fund NBC News at the levels that CBS provided for its news broadcasts. Consequently, CBS News acquired a reputation for greater accuracy and depth in coverage. This reputation meshed well with Cronkite's wire service experience, and in 1967 the CBS Evening News began to surpass The Huntley-Brinkley Report in viewership during the summer months.  In 1969, during the Apollo 11 (with co-host and former astronaut Wally Schirra) and Apollo 13 moon missions, Cronkite received the best ratings and made CBS the most-watched television network for the missions. In 1970, when Huntley retired, the CBS Evening News finally dominated the American TV news viewing audience. Although NBC finally settled on the skilled and well-respected broadcast journalist John Chancellor, Cronkite proved to be more popular and continued to be top-rated until his retirement in 1981.  One of Cronkite's trademarks was ending the CBS Evening News with the phrase "...And that's the way it is," followed by the date. Keeping to standards of objective journalism, he omitted this phrase on nights when he ended the newscast with opinion or commentary. Beginning with January 16, 1980, Day 50 of the Iran hostage crisis, Cronkite added the length of the hostages' captivity to the show's closing in order to remind the audience of the unresolved situation, ending only on Day 444, January 20, 1981.
