Problem: Yale University:

In the wake of the racially-motivated" church shooting in Charleston, South Carolina, Yale was under criticism again in the summer of 2015 for Calhoun College, one of 12 residential colleges, which was named after John C. Calhoun, a slave-owner and strong slavery supporter in the nineteenth century. In July 2015 students signed a petition calling for the name change. They argued in the petition thatwhile Calhoun was respected in the 19th century as an "extraordinary American statesman"he was "one of the most prolific defenders of slavery and white supremacy" in the history of the United States. In August 2015 Yale President Peter Salovey addressed the Freshman Class of 2019 in which he responded to the racial tensions but explained why the college would not be renamed. He described Calhoun as a "a notable political theorist, a vice president to two different U.S. presidents, a secretary of war and of state, and a congressman and senator representing South Carolina." He acknowledged that Calhoun also "believed that the highest forms of civilization depend on involuntary servitude. Not only that, but he also believed that the races he thought to be inferior, black people in particular, ought to be subjected to it for the sake of their own best interests." Racial tensions increased in the fall of 2015 centering on comments by Nicholas A. Christakis and his wife Erika regarding freedom of speech. In April 2016 Salovey announced that "despite decades of vigorous alumni and student protests," Calhoun's name will remain on the Yale residential college explaining that it is preferable for Yale students to live in Calhoun's "shadow" so they will be "better prepared to rise to the challenges of the present and the future." He claimed that if they removed Calhoun's name, it would "obscure" his "legacy of slavery rather than addressing it." "Yale is part of that history" and "We cannot erase American history, but we can confront it, teach it and learn from it." One change that will be issued is the title of "master" for faculty members who serve as residential college leaders will be renamed to "head of college" due to its connotation of slavery.

What title change will be happening to reduce racial tensions?
---
A: the title of "master" for faculty members who serve as residential college leaders will be renamed to "head of college"

Problem: The inventor Nicephore Niepce produced the first permanent photograph on a polished pewter plate in Paris in 1825, and then developed the process with Louis Daguerre. The work of Etienne-Jules Marey in the 1880s contributed considerably to the development of modern photography. Photography came to occupy a central role in Parisian Surrealist activity, in the works of Man Ray and Maurice Tabard. Numerous photographers achieved renown for their photography of Paris, including Eugene Atget, noted for his depictions of street scenes, Robert Doisneau, noted for his playful pictures of people and market scenes (among which Le baiser de l'hotel de ville has became iconic of the romantic vision of Paris), Marcel Bovis, noted for his night scenes, and others such as Jacques-Henri Lartigue and Cartier-Bresson. Poster art also became an important art form in Paris in the late nineteenth century, through the work of Henri de Toulouse-Lautrec, Jules Cheret, Eugene Grasset, Adolphe Willette, Pierre Bonnard, Georges de Feure, Henri-Gabriel Ibels, Gavarni, and Alphonse Mucha.
In what year was the first permanent photograph produced?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Much of the medieval period was a time of power struggles between competing dynasties such as the House of Savoy, the Visconti in northern Italy and the House of Habsburg in Austria and Slovenia. In 1291 to protect themselves from incursions by the Habsburgs, four cantons in the middle of Switzerland drew up a charter that is considered to be a declaration of independence from neighboring kingdoms. After a series of battles fought in the 13th, 14th and 15th centuries, more cantons joined the confederacy and by the 16th century Switzerland was well-established as a separate state.
Much of the medieval period was a time of what?
A: power struggles

Context and question: According to the traditional narrative, several companions of Muhammad served as scribes and were responsible for writing down the revelations. Shortly after Muhammad's death, the Quran was compiled by his companions who wrote down and memorized parts of it. These codices had differences that motivated the Caliph Uthman to establish a standard version now known as Uthman's codex, which is generally considered the archetype of the Quran known today. There are, however, variant readings, with mostly minor differences in meaning.
Who first recorded Muhammad revelations?
Answer: companions of Muhammad

Problem: Roman Republic:

Between 135 BC and 71 BC there were three "Servile Wars" involving slave uprisings against the Roman state. The third and final uprising was the most serious, involving ultimately between 120,000 and 150,000 slaves under the command of the gladiator Spartacus. In 91 BC the Social War broke out between Rome and its former allies in Italy when the allies complained that they shared the risk of Rome's military campaigns, but not its rewards. Although they lost militarily, the allies achieved their objectives with legal proclamations which granted citizenship to more than 500,000 Italians.

How many slaves at most were under the command of Spartacus?

A:
150,000
