Input: Read this: The language was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 1700s. Although most colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. Sizable Russian-speaking communities also exist in North America, especially in large urban centers of the U.S. and Canada, such as New York City, Philadelphia, Boston, Los Angeles, Nashville, San Francisco, Seattle, Spokane, Toronto, Baltimore, Miami, Chicago, Denver and Cleveland. In a number of locations they issue their own newspapers, and live in ethnic enclaves (especially the generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union, the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to the United States Census, in 2007 Russian was the primary language spoken in the homes of over 850,000 individuals living in the United States.
Question: Where did Russian explorers first reach North America?

Output: Alaska

QUES: The Uniform Crime Reports (UCR) compile data from over 17,000 law enforcement agencies across the country. They provide detailed data regarding the volume of crimes to include arrest, clearance (or closing a case), and law enforcement officer information. The UCR focuses its data collection on violent crimes, hate crimes, and property crimes. Created in the 1920s, the UCR system has not proven to be as uniform as its name implies. The UCR data only reflect the most serious offense in the case of connected crimes and has a very restrictive definition of rape. Since about 93% of the data submitted to the FBI is in this format, the UCR stands out as the publication of choice as most states require law enforcement agencies to submit this data.

When was the UCR disbanded?

QUES: With the arrival of Francisco Vazquez de Coronado, a Spanish conquistador, the first recorded history of encounter between Europeans and Native Americans in the Great Plains occurred in Texas, Kansas and Nebraska from 1540-1542. In that same time period, Hernando de Soto crossed a west-northwest direction in what is now Oklahoma and Texas. Today this is known as the De Soto Trail. The Spanish thought the Great Plains were the location of the mythological Quivira and Cibola, a place said to be rich in gold.
who crossed a section of oklahoma and texas?

ANS: Hernando de Soto

Barcelona is the only European club to have played continental football every season since 1955, and one of three clubs to have never been relegated from La Liga, along with Athletic Bilbao and Real Madrid. In 2009, Barcelona became the first club in Spain to win the treble consisting of La Liga, Copa del Rey, and the Champions League. That same year, it also became the first football club ever to win six out of six competitions in a single year, thus completing the sextuple, comprising the aforementioned treble and the Spanish Super Cup, UEFA Super Cup and FIFA Club World Cup. In the 201415 season, Barcelona won another historic treble, making them the first club in European football to win the treble twice.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What team has played continental football every season since 1955?
Ah, so.. Barcelona

Question: In the mid-fifteenth century, the religion of Sikhism was born. During the Mughal empire, many Hindus increasingly adopted Sikhism. These became a formidable military force against the Mughals and later against the Afghan Empire. After fighting Ahmad Shah Durrani in the later eighteenth century, the Sikhs took control of Punjab and managed to establish the Sikh Empire under Maharaja Ranjit Singh, which lasted from 1799 to 1849. The capital of Ranjit Singh's empire was Lahore, and the empire also extended into Afghanistan and Kashmir. Bhangi Misl was the fist Sikh band to conquer Lahore and other towns of Punjab. Syed Ahmad Barelvi a Muslim, waged jihad and attempted to create an Islamic state with strict enforcement of Islamic law. Syed Ahmad Barelvi in 1821 with many supporters and spent two years organising popular and material support for his Punjab campaign. He carefully developed a network of people through the length and breadth of India to collect funds and encourage volunteers, travelling widely throughout India attracting a following among pious Muslims. In December 1826 Sayyid Ahmad and his followers clashed with Sikh troops at Akora Khattak, but with no decisive result. In a major battle near the town of Balakot in 1831, Sayyid Ahmad and Shah Ismail Shaheed with volunteer Muslims were defeated by the professional Sikh Army.

Problem: Bipolar transistors are so named because they conduct by using both majority and minority carriers. The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes, and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an npn transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a pnp transistor). This construction produces two pn junctions: a baseemitter junction and a basecollector junction, separated by a thin region of semiconductor known as the base region (two junction diodes wired together without sharing an intervening semiconducting region will not make a transistor).
What is the name for a layer of n-type semiconductor set between two p-type semiconductors?
---
Answer:
pnp transistor
