Problem: Given the question: This article: Washington, D.C., formally the District of Columbia and commonly referred to as Washington or D.C., is the capital of the United States. Founded after the American Revolution as the seat of government of the newly independent country, Washington was named after George Washington, the first President of the United States and a Founding Father. As the seat of the United States federal government and several international organizations, Washington is an important world political capital. The city is also one of the most visited cities in the world, with more than 20 million tourists annually.The signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River on the country's East Coast. The U.S. Constitution provided for a federal district under the exclusive jurisdiction of the U.S. Congress, and the District is therefore not a part of any state. The states of Maryland and Virginia each donated land to form the federal district, which included the pre-existing settlements of Georgetown and Alexandria. The City of Washington was founded in 1791 to serve as the new national capital. In 1846, Congress returned the land originally ceded by Virginia; in 1871, it created a single municipal government for the remaining portion of the District. Washington had an estimated population of 702,455 as of July 2018, making it the 20th most populous city in the United States. Commuters from the surrounding Maryland and Virginia suburbs raise the city's daytime population to more than one million during the workweek. Washington's metropolitan area, the country's sixth largest, had a 2017 estimated population of 6.2 million residents.All three branches of the U.S. federal government are centered in the District: Congress (legislative), president (executive), and the U.S. Supreme Court (judicial). Washington is home to many national monuments, and museums, primarily situated on or around the National Mall. The city hosts 177 foreign embassies as well as the headquarters... contains an answer for the question: What is the country wide population ranking of the city that houses all 3 branches of the U.S federal government?, what is it ?

Problem: Given the question: This article: By the time Smetana completed his schooling, his father's fortunes had declined. Although Frantisek now agreed that his son should follow a musical career, he could not provide financial support. In August 1843 Smetana departed for Prague with twenty gulden, and no immediate prospects. Lacking any formal musical training, he needed a teacher, and was introduced by Katerina Kolarova's mother to Josef Proksch, head of the Prague Music Institutewhere Katerina was now studying. Proksch used the most modern teaching methods, drawing on Beethoven, Chopin, Berlioz and the Leipzig circle of Liszt. In January 1844 Proksch agreed to take Smetana as a pupil, and at the same time the young musician's financial difficulties were eased when he secured an appointment as music teacher to the family of a nobleman, Count Thun.For the next three years, besides teaching piano to the Thun children, Smetana studied theory and composition under Proksch. The works he composed in these years include songs, dances, bagatelles, impromptus and the G minor Piano Sonata. In 1846 Smetana attended concerts given in Prague by Berlioz, and in all likelihood met the French composer at a reception arranged by Proksch. At the home of Count Thun he met Robert and Clara Schumann, and showed them his G minor sonata, but failed to win their approval for this workthey detected too much of Berlioz in it. Meanwhile, his friendship with Katerina blossomed. In June 1847, on resigning his position in the Thun household, Smetana recommended her as his replacement. He then set out on a tour of Western Bohemia, hoping to establish a reputation as a concert pianist. contains an answer for the question: What is the name of the person that was appointed as a music teacher?, what is it ?
