The Battle for Mexico City was the series of engagements from September 8 to September 15, 1847, in the general vicinity of Mexico City during the MexicanAmerican War. Included are major actions at the battles of Molino del Rey and Chapultepec, culminating with the fall of Mexico City. The U.S. Army under Winfield Scott scored a major success that ended the war. The American invasion into the Federal District was first resisted during the Battle of Churubusco on August 8 where the Saint Patrick's Battalion, which was composed primarily of Catholic Irish and German immigrants, but also Canadians, English, French, Italians, Poles, Scots, Spaniards, Swiss, and Mexican people, fought for the Mexican cause repelling the American attacks. After defeating the Saint Patrick's Battalion, the MexicanAmerican War came to a close after the United States deployed combat units deep into Mexico resulting in the capture of Mexico City and Veracruz by the U.S. Army's 1st, 2nd, 3rd and 4th Divisions. The invasion culminated with the storming of Chapultepec Castle in the city itself.

Input: Military history of the United States
Sectional tensions had long existed between the states located north of the MasonDixon line and those south of it, primarily centered on the "peculiar institution" of slavery and the ability of states to overrule the decisions of the national government. During the 1840s and 1850s, conflicts between the two sides became progressively more violent. After the election of Abraham Lincoln in 1860 (who southerners thought would work to end slavery) states in the South seceded from the United States, beginning with South Carolina in late 1860. On April 12, 1861, forces of the South (known as the Confederate States of America or simply the Confederacy) opened fire on Fort Sumter, whose garrison was loyal to the Union.

When did Confederate forces bombard Fort Sumter?
Output: April 12, 1861

Input: The Blitz
The most important existing communal shelters were the London Underground stations. Although many civilians had used them as such during the First World War, the government in 1939 refused to allow the stations to be used as shelters so as not to interfere with commuter and troop travel, and the fears that occupants might refuse to leave. Underground officials were ordered to lock station entrances during raids; but by the second week of heavy bombing the government relented and ordered the stations to be opened. Each day orderly lines of people queued until 4 pm, when they were allowed to enter the stations. In mid-September 1940 about 150,000 a night slept in the Underground, although by the winter and spring months the numbers had declined to 100,000 or less. Noises of battle were muffled and sleep was easier in the deepest stations, but many were killed from direct hits on several stations.

Why were many killed in Underground Stations?
Output: direct hits

Input: Frederic Chopin
All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some songs to Polish lyrics. His keyboard style is highly individual and often technically demanding; his own performances were noted for their nuance and sensitivity. Chopin invented the concept of instrumental ballade. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, etudes, impromptus, scherzos, preludes and sonatas, some published only after his death. Influences on his compositional style include Polish folk music, the classical tradition of J. S. Bach, Mozart and Schubert, the music of all of whom he admired, as well as the Paris salons where he was a frequent guest. His innovations in style, musical form, and harmony, and his association of music with nationalism, were influential throughout and after the late Romantic period.

What language were some songs written in that Chopin wrote music for?
Output:
Polish
