Problem: Multiracial American:

In 1790, the first federal population census was taken in the United States. Enumerators were instructed to classify free residents as white or "other." Only the heads of households were identified by name in the federal census until 1850. Native Americans were included among "Other;" in later censuses, they were included as "Free people of color" if they were not living on Indian reservations. Slaves were counted separately from free persons in all the censuses until the Civil War and end of slavery. In later censuses, people of African descent were classified by appearance as mulatto (which recognized visible European ancestry in addition to African) or black.

Who all was identified by name in the house holds?
---
A: Only the heads of households


Problem: In 1870, after France attacked Prussia, Prussia and its new allies in Southern Germany (among them Bavaria) were victorious in the Franco-Prussian War. It created the German Empire in 1871 as a German nation-state, effectively excluding the multi-ethnic Austrian Habsburg monarchy and Liechtenstein. Integrating the Austrians nevertheless remained a strong desire for many people of Germany and Austria, especially among the liberals, the social democrats and also the Catholics who were a minority within the Protestant Germany.
Who was excluded from the German Nation State?
---
Answer: Austrian Habsburg monarchy and Liechtenstein


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
With Yoritomo firmly established, the bakufu system that would govern Japan for the next seven centuries was in place. He appointed military governors, or daimyos, to rule over the provinces, and stewards, or jito to supervise public and private estates. Yoritomo then turned his attention to the elimination of the powerful Fujiwara family, which sheltered his rebellious brother Yoshitsune. Three years later, he was appointed shogun in Kyoto. One year before his death in 1199, Yoritomo expelled the teenage emperor Go-Toba from the throne. Two of Go-Toba's sons succeeded him, but they would also be removed by Yoritomo's successors to the shogunate.
What was the name of the emperor that Yoritomo removed from the throne?
A: Go-Toba


Context and question: The enormous success of the show and the revenue it generated was transformative for Fox Broadcasting Company. American Idol and fellow competing shows Survivor and Who Wants to Be a Millionaire were altogether credited for expanding reality television programming in the United States in the 1990s and 2000s, and Idol became the most watched non-scripted primetime television series for almost a decade, from 2003 to 2012, breaking records on U.S. television (dominated by drama shows and sitcoms in the preceding decades).
For how many years was American Idol the highest rated reality show on television?
Answer: 9


Question: The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance — as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.
Is there an answer to this question: What was not a problem for early carbon filaments?

Answer: unanswerable


QUES: The U.S. Census Bureau reports a 2010 population of 129,779, with 47,094 households and 25,854 families within the city of New Haven. The population density is 6,859.8 people per square mile (2,648.6/km²). There are 52,941 housing units at an average density of 2,808.5 per square mile (1,084.4/km²). The racial makeup of the city is 42.6% White, 35.4% African American, 0.5% Native American, 4.6% Asian, 0.1% Pacific Islander, 12.9% from other races, and 3.9% from two or more races. Hispanic or Latino residents of any race were 27.4% of the population. Non-Hispanic Whites were 31.8% of the population in 2010, down from 69.6% in 1970. The city's demography is shifting rapidly: New Haven has always been a city of immigrants and currently the Latino population is growing rapidly. Previous influxes among ethnic groups have been African-Americans in the postwar era, and Irish, Italian and (to a lesser degree) Slavic peoples in the prewar period.

In terms of population density, what is the average person per square kilometers in New Haven?
What is the answer?
ANS:
2,648.6/km²
