Please answer this: Question: "A music piece intended to be played with only vocal singers, and is not accompanied with any musical instrument is?" Context: "The Swingle Singers used nonsense words to sound like instruments, but have been known to produce non-verbal versions of musical instruments. Like the other groups, examples of their music can be found on YouTube. Beatboxing, more accurately known as vocal percussion, is a technique used in a cappella music popularized by the hip-hop community, where rap is often performed a cappella also. The advent of vocal percussion added new dimensions to the a cappella genre and has become very prevalent in modern arrangements. Petra Haden used a four-track recorder to produce an a cappella version of The Who Sell Out including the instruments and fake advertisements on her album Petra Haden Sings: The Who Sell Out in 2005. Haden has also released a cappella versions of Journey's "Don't Stop Believin'", The Beach Boys' "God Only Knows" and Michael Jackson's "Thriller". In 2009, Toyota commissioned Haden to perform three songs for television commercials for the third-generation Toyota Prius, including an a cappella version of The Bellamy Brothers' 1970s song "Let Your Love Flow".[citation needed]" Answer:

Problem: Question: "__ is sister cities with Avignon, France." Context: "In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 18 white firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no black firefighters scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. In the subsequent Ricci v. DeStefano decision the court found 5-4 that New Haven's decision to ignore the test results violated Title VII of the Civil Rights Act of 1964. As a result, a district court subsequently ordered the city to promote 14 of the white firefighters." Answer:

A: New Haven

Problem: Given the question: Question: "What humour did europaeus have?" Context: "The first post-Classical published classification of humans into distinct races seems to be Francois Bernier's Nouvelle division de la terre par les differents especes ou races qui l'habitent ("New division of Earth by the different species or races which inhabit it"), published in 1684. In the 18th century the differences among human groups became a focus of scientific investigation. But the scientific classification of phenotypic variation was frequently coupled with racist ideas about innate predispositions of different groups, always attributing the most desirable features to the White, European race and arranging the other races along a continuum of progressively undesirable attributes. The 1735 classification of Carl Linnaeus, inventor of zoological taxonomy, divided the human race Homo sapiens into continental varieties of europaeus, asiaticus, americanus, and afer, each associated with a different humour: sanguine, melancholic, choleric, and phlegmatic, respectively. Homo sapiens europaeus was described as active, acute, and adventurous, whereas Homo sapiens afer was said to be crafty, lazy, and careless." Answer:

Q: Question: "What was Sam's educational background?" Context: "During the period from 1993 to 2011, FBI agents fired their weapons on 289 occasions; FBI internal reviews found the shots justified in all but 5 cases, in none of the 5 cases were people wounded. Samuel Walker, a professor of criminal justice at the University of Nebraska Omaha said the number of shots found to be unjustified was "suspiciously low." In the same time period, the FBI wounded 150 people, 70 of whom died; the FBI found all 150 shootings to be justified. Likewise, during the period from 2011 to the present, all shootings by FBI agents have been found to be justified by internal investigation. In a 2002 case in Maryland, an innocent man was shot, and later paid $1.3 million by the FBI after agents mistook him for a bank robber; the internal investigation found that the shooting was justified, based on the man's actions." Answer:
A:
criminal justice
