Problem: Detroit has struggled with high crime for decades. Detroit held the title of murder capital between 1985-1987 with a murder rate around 58 per 100,000. Crime has since decreased and, in 2014, the murder rate was 43.4 per 100,000, lower than in St. Louis, Missouri. Although the murder rate increased by 6% during the first half of 2015, it was surpassed by St Louis and Baltimore which saw much greater spikes in violence. At year-end 2015, Detroit had 295 criminal homicides, down slightly from 299 in 2014.
What was Detroit's murder rate in 2014?
The answer is the following: 43.4 per 100,000


The centrality of the "separation" concept to the Religion Clauses of the Constitution was made explicit in Everson v. Board of Education, 330 U.S. 1 (1947), a case dealing with a New Jersey law that allowed government funds to pay for transportation of students to both public and Catholic schools. This was the first case in which the court applied the Establishment Clause to the laws of a state, having interpreted the due process clause of the Fourteenth Amendment as applying the Bill of Rights to the states as well as the federal legislature. Citing Jefferson, the court concluded that "The First Amendment has erected a wall between church and state. That wall must be kept high and impregnable. We could not approve the slightest breach."
What case was the concept relevant?
Everson v. Board of Education, 330 U.S. 1


Input: Frédéric Chopin
Chopin's relations with Sand were soured in 1846 by problems involving her daughter Solange and Solange's fiancé, the young fortune-hunting sculptor Auguste Clésinger. The composer frequently took Solange's side in quarrels with her mother; he also faced jealousy from Sand's son Maurice. Chopin was utterly indifferent to Sand's radical political pursuits, while Sand looked on his society friends with disdain. As the composer's illness progressed, Sand had become less of a lover and more of a nurse to Chopin, whom she called her "third child". In letters to third parties, she vented her impatience, referring to him as a "child," a "little angel", a "sufferer" and a "beloved little corpse." In 1847 Sand published her novel Lucrezia Floriani, whose main characters—a rich actress and a prince in weak health—could be interpreted as Sand and Chopin; the story was uncomplimentary to Chopin, who could not have missed the allusions as he helped Sand correct the printer's galleys. In 1847 he did not visit Nohant, and he quietly ended their ten-year relationship following an angry correspondence which, in Sand's words, made "a strange conclusion to nine years of exclusive friendship." The two would never meet again.

What was the name of Sand's daughter's fiance that contributed to deteriorating the relationship between Sand and Chopin?
Output: Auguste Clésinger


Input: Article: During the latter half of the 20th century, Washington University transitioned from a strong regional university to a national research institution. In 1957, planning began for the construction of the “South 40,” a complex of modern residential halls. With the additional on-campus housing, Washington University, which had been predominantly a “streetcar college” of commuter students, began to attract a more national pool of applicants. By 1964, over two-thirds of incoming students came from outside the St. Louis area.

Now answer this question: What name was given to the new residential complex constructed at Washington University?

Output: South 40


Problem: Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.
A component might not be able to be made any smaller because of its mechanical limitations or what other need?
The answer is the following:
power requirements
