Question: What rivers provide boundaries for Manhattan, the most densely populated borough in New York City and the 111 Murray Street residential skyscraper located in Manhattan?

full_context: Document 1: Financial District, Manhattan: The Financial District, also known as FiDi, is a neighborhood located at the southern tip of the borough of Manhattan in New York City, which comprises the offices and headquarters of many of the city's major financial institutions, including the New York Stock Exchange and the Federal Reserve Bank of New York. Anchored on Wall Street in the Financial District, New York City has been called both the most financially powerful city and the leading financial center of the world, and the New York Stock Exchange is the world's largest stock exchange by total market capitalization. Several other major exchanges have or had headquarters in the Financial District, including the New York Mercantile Exchange, NASDAQ, the New York Board of Trade, and the former American Stock Exchange.
Document 2: The Bronx: The Bronx ( ) is the northernmost of the five boroughs of New York City, within the U.S. state of New York. It is geographically south of Westchester County; north and east of the island and borough of Manhattan to the south and west across the Harlem River; and north of the borough of Queens, across the East River. Of the five boroughs, the Bronx is the only one that has the majority of its area on the U.S. mainland and, with a land area of 42 sqmi and a population of 1,455,720 in 2016, has the fourth-largest land area, the fourth-highest population, and the third-highest population density. Since 1914, the Bronx has had the same boundaries as Bronx County, a county of New York and the third most densely populated county in the United States.
Document 3: Manhattanization: Manhattanization is a neologism coined to describe the construction of many tall or densely situated buildings, which transforms the appearance and character of a city to resemble Manhattan, a heavily and densely populated borough of New York City. It was a pejorative word used by critics of the highrise buildings built in San Francisco during the 1960s and 1970s, who claimed the skyscrapers would block views of the bay and the surrounding hills. With careful urban planning, the phenomenon became more accepted in time. The term also gained usage as a buzzword for high-density developments in Las Vegas, Nevada, Los Angeles, Dubai, and Miami in the early 2000s and again in the 2010s. Another example is the construction boom in Toronto since 2007. The term has even been applied to many smaller US cities that have seen a large spike in downtown high rise rental buildings since the year 2000. Nonetheless, these cities would have to multiply their populations many times over to match the population density of Manhattan, though this is a biased comparison between a city and a district, as even the other four "outer boroughs" of New York City would have to nearly triple in population to match Manhattan's current density. Likewise, the just over 1 sqmi Brickell (Miami) financial district is more dense than New York City overall.
Document 4: American Copper Buildings: American Copper Buildings (originally known as 626 First Avenue) is a dual-tower residential skyscraper in the Murray Hill neighborhood of New York City, in Manhattan.

Document 5: Long Island: The Long Island is a large, densely-populated island off the East Coast of the United States, beginning at New York Harbor just 0.35 miles (0.56 km) from Manhattan Island and extending eastward into the Atlantic Ocean. The island comprises four counties in the U.S. state of New York: Kings and Queens (which comprise the New York City boroughs of Brooklyn and Queens, respectively) to the west; and Nassau and Suffolk to the east. However, many people in the New York metropolitan area (even those living in Brooklyn and Queens) colloquially use the term "Long Island" (or "The Island") exclusively to refer to the Nassau–Suffolk county area collectively, which is mainly suburban in character. The majority of New York City residents now live on Long Island.
