Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of which is a separate county of New York State. The five boroughs – Brooklyn, Queens, Manhattan, the Bronx, and Staten Island – were consolidated into a single city in 1898. With a census-estimated 2014 population of 8,491,079 distributed over a land area of just 305 square miles (790 km2), New York is the most densely populated major city in the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. By 2014 census estimates, the New York City metropolitan region remains by a significant margin the most populous in the United States, as defined by both the Metropolitan Statistical Area (20.1 million residents) and the Combined Statistical Area (23.6 million residents). In 2013, the MSA produced a gross metropolitan product (GMP) of nearly US$1.39 trillion, while in 2012, the CSA generated a GMP of over US$1.55 trillion, both ranking first nationally by a wide margin and behind the GDP of only twelve and eleven countries, respectively.

How many languages are spoken by the people of New York City?
Answer: 800


Problem: The subsequent Slave dynasty of Delhi managed to conquer large areas of northern India, while the Khilji dynasty conquered most of central India but were ultimately unsuccessful in conquering and uniting the subcontinent. The Sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu (literally meaning "horde" or "camp" in various Turkic dialects) was born during the Delhi Sultanate period as a result of the intermingling of the local speakers of Sanskritic Prakrits with immigrants speaking Persian, Turkic, and Arabic under the Muslim rulers. The Delhi Sultanate is the only Indo-Islamic empire to enthrone one of the few female rulers in India, Razia Sultana (1236–1240).
By what is the fusion of Islamic and Indian cultures called?
The answer is the following: Indo-Muslim


The United Nations estimates that the population in 2009 was at 154,729,000, distributed as 51.7% rural and 48.3% urban, and with a population density of 167.5 people per square kilometre. National census results in the past few decades have been disputed. The results of the most recent census were released in December 2006 and gave a population of 140,003,542. The only breakdown available was by gender: males numbered 71,709,859, females numbered 68,293,08. On June 2012, President Goodluck Jonathan said that Nigerians should limit their number of children.
What was Nigeria's population density in 2009?
167.5 people per square kilometre


Input: Age of Enlightenment
Coffeehouses were especially important to the spread of knowledge during the Enlightenment because they created a unique environment in which people from many different walks of life gathered and shared ideas. They were frequently criticized by nobles who feared the possibility of an environment in which class and its accompanying titles and privileges were disregarded. Such an environment was especially intimidating to monarchs who derived much of their power from the disparity between classes of people. If classes were to join together under the influence of Enlightenment thinking, they might recognize the all-encompassing oppression and abuses of their monarchs and, because of their size, might be able to carry out successful revolts. Monarchs also resented the idea of their subjects convening as one to discuss political matters, especially those concerning foreign affairs - rulers thought political affairs to be their business only, a result of their supposed divine right to rule. 

Which venue created a unique environment in which people from many different walks of life could gather and share ideas?
Output: Coffeehouses


Input: Article: At a certain temperature, (usually between 1,500 °F (820 °C) and 1,600 °F (870 °C), depending on carbon content), the base metal of steel undergoes a change in the arrangement of the atoms in its crystal matrix, called allotropy. This allows the small carbon atoms to enter the interstices of the iron crystal, diffusing into the iron matrix. When this happens, the carbon atoms are said to be in solution, or mixed with the iron, forming a single, homogeneous, crystalline phase called austenite. If the steel is cooled slowly, the iron will gradually change into its low temperature allotrope. When this happens the carbon atoms will no longer be soluble with the iron, and will be forced to precipitate out of solution, nucleating into the spaces between the crystals. The steel then becomes heterogeneous, being formed of two phases; the carbon (carbide) phase cementite, and ferrite. This type of heat treatment produces steel that is rather soft and bendable. However, if the steel is cooled quickly the carbon atoms will not have time to precipitate. When rapidly cooled, a diffusionless (martensite) transformation occurs, in which the carbon atoms become trapped in solution. This causes the iron crystals to deform intrinsically when the crystal structure tries to change to its low temperature state, making it very hard and brittle.

Now answer this question: Soft and bendable steel is caused by what?

Output: If the steel is cooled slowly


Problem: The insect outer skeleton, the cuticle, is made up of two layers: the epicuticle, which is a thin and waxy water resistant outer layer and contains no chitin, and a lower layer called the procuticle. The procuticle is chitinous and much thicker than the epicuticle and has two layers: an outer layer known as the exocuticle and an inner layer known as the endocuticle. The tough and flexible endocuticle is built from numerous layers of fibrous chitin and proteins, criss-crossing each other in a sandwich pattern, while the exocuticle is rigid and hardened.:22–24 The exocuticle is greatly reduced in many soft-bodied insects (e.g., caterpillars), especially during their larval stages.
Is the procuticle thinner or thicker than the epicuticle?
The answer is the following:
thicker
