Input: Article: People of Irish descent form the largest single ethnic group in the city, making up 15.8% of the population, followed by Italians, accounting for 8.3% of the population. People of West Indian and Caribbean ancestry are another sizable group, at 6.0%, about half of whom are of Haitian ancestry. Over 27,000 Chinese Americans made their home in Boston city proper in 2013, and the city hosts a growing Chinatown accommodating heavily traveled Chinese-owned bus lines to and from Chinatown, Manhattan. Some neighborhoods, such as Dorchester, have received an influx of people of Vietnamese ancestry in recent decades. Neighborhoods such as Jamaica Plain and Roslindale have experienced a growing number of Dominican Americans. The city and greater area also has a growing immigrant population of South Asians, including the tenth-largest Indian community in the country.

Now answer this question: What is the second largest ethnic group in the city?

Output: Italians

Input: Article: Neptune's more varied weather when compared to Uranus is due in part to its higher internal heating. Although Neptune lies over 50% further from the Sun than Uranus, and receives only 40% its amount of sunlight, the two planets' surface temperatures are roughly equal. The upper regions of Neptune's troposphere reach a low temperature of 51.8 K (221.3 C). At a depth where the atmospheric pressure equals 1 bar (100 kPa), the temperature is 72.00 K (201.15 C). Deeper inside the layers of gas, the temperature rises steadily. As with Uranus, the source of this heating is unknown, but the discrepancy is larger: Uranus only radiates 1.1 times as much energy as it receives from the Sun; whereas Neptune radiates about 2.61 times as much energy as it receives from the Sun. Neptune is the farthest planet from the Sun, yet its internal energy is sufficient to drive the fastest planetary winds seen in the Solar System. Depending on the thermal properties of its interior, the heat left over from Neptune's formation may be sufficient to explain its current heat flow, though it is more difficult to simultaneously explain Uranus's lack of internal heat while preserving the apparent similarity between the two planets.

Now answer this question: The current heat flow on Neptune might be explained by what?

Output: heat left over from Neptune's formation

Input: Article: New York City is home to the headquarters of the National Football League, Major League Baseball, the National Basketball Association, the National Hockey League, and Major League Soccer. The New York metropolitan area hosts the most sports teams in these five professional leagues. Participation in professional sports in the city predates all professional leagues, and the city has been continuously hosting professional sports since the birth of the Brooklyn Dodgers in 1882. The city has played host to over forty major professional teams in the five sports and their respective competing leagues, both current and historic. Four of the ten most expensive stadiums ever built worldwide (MetLife Stadium, the new Yankee Stadium, Madison Square Garden, and Citi Field) are located in the New York metropolitan area. Madison Square Garden, its predecessor, as well as the original Yankee Stadium and Ebbets Field, are some of the most famous sporting venues in the world, the latter two having been commemorated on U.S. postage stamps.

Now answer this question: Which two sports stadiums of New York City were featured on US stamps?

Output:
the original Yankee Stadium and Ebbets Field
