Problem: BBC Television:

The BBC domestic television channels do not broadcast advertisements; they are instead funded by a television licence fee which TV viewers are required to pay annually. This includes viewers who watch real-time streams of the BBC's channels online or via their mobile phone. The BBC's international television channels are funded by advertisements and subscription.

Context and question: Communication is usually described along a few major dimensions: Message (what type of things are communicated), source / emisor / sender / encoder (by whom), form (in which form), channel (through which medium), destination / receiver / target / decoder (to whom), and Receiver. Wilbur Schram (1954) also indicated that we should also examine the impact that a message has (both desired and undesired) on the target of the message. Between parties, communication includes acts that confer knowledge and experiences, give advice and commands, and ask questions. These acts may take many forms, in one of the various manners of communication. The form depends on the abilities of the group communicating. Together, communication content and form make messages that are sent towards a destination. The target can be oneself, another person or being, another entity (such as a corporation or group of beings).
What is one dimension that communication is typically described along?
Answer: channel (through which medium)

Question: In Paris' Roman era, its main cemetery was located to the outskirts of the Left Bank settlement, but this changed with the rise of Catholicism, where most every inner-city church had adjoining burial grounds for use by their parishes. With Paris' growth many of these, particularly the city's largest cemetery, les Innocents, were filled to overflowing, creating quite unsanitary conditions for the capital. When inner-city burials were condemned from 1786, the contents of all Paris' parish cemeteries were transferred to a renovated section of Paris' stone mines outside the "Porte d'Enfer" city gate, today place Denfert-Rochereau in the 14th arrondissement. The process of moving bones from Cimetiere des Innocents to the catacombs took place between 1786 and 1814; part of the network of tunnels and remains can be visited today on the official tour of the catacombs.
Is there an answer to this question: During what years were the bones moved from Cimetiere des Innocents to the catacombs?

Answer: 1786 and 1814

At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
When was a new sytle of carved top and back construction mandolins created?
A:
end of the 19th century
