Problem: Charleston, South Carolina:

Industries slowly brought the city and its inhabitants back to a renewed vitality and jobs attracted new residents. As the city's commerce improved, residents worked to restore or create community institutions. In 1865, the Avery Normal Institute was established by the American Missionary Association as the first free secondary school for Charleston's African American population. General William T. Sherman lent his support to the conversion of the United States Arsenal into the Porter Military Academy, an educational facility for former soldiers and boys left orphaned or destitute by the war. Porter Military Academy later joined with Gaud School and is now a university-preparatory school, Porter-Gaud School.

oldiers and boys helped by Porter Military Academy weren't affected by what?

Problem: Interpreters have sometimes played crucial roles in history. A prime example is La Malinche, also known as Malintzin, Malinalli and Dona Marina, an early-16th-century Nahua woman from the Mexican Gulf Coast. As a child she had been sold or given to Maya slave-traders from Xicalango, and thus had become bilingual. Subsequently given along with other women to the invading Spaniards, she became instrumental in the Spanish conquest of Mexico, acting as interpreter, adviser, intermediary and lover to Hernan Cortes.
In addition to being an interpreter and adviser, what function did La Malinche serve for Hernan Cortes?

Answer: lover

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The High Middle Ages was a period of tremendous expansion of population. The estimated population of Europe grew from 35 to 80 million between 1000 and 1347, although the exact causes remain unclear: improved agricultural techniques, the decline of slaveholding, a more clement climate and the lack of invasion have all been suggested. As much as 90 per cent of the European population remained rural peasants. Many were no longer settled in isolated farms but had gathered into small communities, usually known as manors or villages. These peasants were often subject to noble overlords and owed them rents and other services, in a system known as manorialism. There remained a few free peasants throughout this period and beyond, with more of them in the regions of Southern Europe than in the north. The practice of assarting, or bringing new lands into production by offering incentives to the peasants who settled them, also contributed to the expansion of population.
About how many millions of people lived in Europe in the year 1000?
A: 35

Context and question: Television personality Piers Morgan, a former editor of the Daily Mirror and of The Sun's Bizarre pop column, has said that during the late 1980s, at Kelvin MacKenzie's behest, he was ordered to speculate on the sexuality of male pop stars for a feature headlined "The Poofs of Pop". He also recalls MacKenzie headlining a January 1989 story about the first same-sex kiss on the BBC television soap opera EastEnders "EastBenders", describing the kiss between Colin Russell and Guido Smith as "a homosexual love scene between yuppie poofs ... when millions of children were watching".
Which column did Piers Morgan edit at The Sun?
Answer: Bizarre pop column

Question: All the major British cities had flourishing department stores by the mid-or late nineteenth century. Increasingly, women became the major shoppers and middle-class households. Kendals (formerly Kendal Milne & Faulkner) in Manchester lays claim to being one of the first department stores and is still known to many of its customers as Kendal's, despite its 2005 name change to House of Fraser. The Manchester institution dates back to 1836 but had been trading as Watts Bazaar since 1796. At its zenith the store had buildings on both sides of Deansgate linked by a subterranean passage "Kendals Arcade" and an art nouveau tiled food hall. The store was especially known for its emphasis on quality and style over low prices giving it the nickname "the Harrods of the North", although this was due in part to Harrods acquiring the store in 1919. Other large Manchester stores included Paulden's (currently Debenhams) and Lewis's (now a Primark).
Is there an answer to this question: What did Kendals change it's name to in 2005?

Answer: House of Fraser

Problem: Videoconferencing:

A videoconference system is generally higher cost than a videophone and deploys greater capabilities. A videoconference (also known as a videoteleconference) allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. This is often accomplished by the use of a multipoint control unit (a centralized distribution and call management system) or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. Again, technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications.

What is a multi-point control unit?
---
A:
call management system
