Article: There is a theory that vinyl records can audibly represent higher frequencies than compact discs. According to Red Book specifications, the compact disc has a frequency response of 20 Hz up to 22,050 Hz, and most CD players measure flat within a fraction of a decibel from at least 20 Hz to 20 kHz at full output. Turntable rumble obscures the low-end limit of vinyl but the upper end can be, with some cartridges, reasonably flat within a few decibels to 30 kHz, with gentle roll-off. Carrier signals of Quad LPs popular in the 1970s were at 30 kHz to be out of the range of human hearing. The average human auditory system is sensitive to frequencies from 20 Hz to a maximum of around 20,000 Hz. The upper and lower frequency limits of human hearing vary per person.

Question: Does the hearing range of the human vary?
Ans: The upper and lower frequency limits of human hearing vary per person

Here is a question about this article: The writers of Grub Street, the Grub Street Hacks, were left feeling bitter about the relative success of the men of letters, and found an outlet for their literature which was typified by the libelle. Written mostly in the form of pamphlets, the libelles "slandered the court, the Church, the aristocracy, the academies, the salons, everything elevated and respectable, including the monarchy itself". Le Gazetier cuirasse by Charles Theveneau de Morande was a prototype of the genre. It was Grub Street literature that was most read by the public during the Enlightenment. More importantly, according to Darnton, the Grub Street hacks inherited the "revolutionary spirit" once displayed by the philosophes, and paved the way for the French Revolution by desacralizing figures of political, moral and religious authority in France.
What is the answer to this question: Which group inherited the "revolutionary spirit" once displayed by the philosophes, according to Darnton?
****
So... the Grub Street hacks

Problem: Please answer a question about the following article about A cappella:
It is not clear exactly where collegiate a cappella began. The Rensselyrics of Rensselaer Polytechnic Institute (formerly known as the RPI Glee Club), established in 1873 is perhaps the oldest known collegiate a cappella group.[citation needed] However the longest continuously-singing group is probably The Whiffenpoofs of Yale University, which was formed in 1909 and once included Cole Porter as a member. Collegiate a cappella groups grew throughout the 20th century. Some notable historical groups formed along the way include Princeton University's Tigertones (1946), Colgate University's The Colgate 13 (1942), Dartmouth College's Aires (1946), Cornell University's Cayuga's Waiters (1949) and The Hangovers (1968), the University of Maine Maine Steiners (1958), the Columbia University Kingsmen (1949), the Jabberwocks of Brown University (1949), and the University of Rochester YellowJackets (1956). All-women a cappella groups followed shortly, frequently as a parody of the men's groups: the Smiffenpoofs of Smith College (1936), The Shwiffs of Connecticut College (The She-Whiffenpoofs, 1944), and The Chattertocks of Brown University (1951). A cappella groups exploded in popularity beginning in the 1990s, fueled in part by a change in style popularized by the Tufts University Beelzebubs and the Boston University Dear Abbeys. The new style used voices to emulate modern rock instruments, including vocal percussion/"beatboxing". Some larger universities now have multiple groups. Groups often join one another in on-campus concerts, such as the Georgetown Chimes' Cherry Tree Massacre, a 3-weekend a cappella festival held each February since 1975, where over a hundred collegiate groups have appeared, as well as International Quartet Champions The Boston Common and the contemporary commercial a cappella group Rockapella. Co-ed groups have produced many up-and-coming and major artists, including John Legend, an alumnus of the Counterparts at the University of Pennsylvania, and Sara Bareilles, an alumna of Awaken A Cappella at University of California, Los Angeles. Mira Sorvino is an alumna of the Harvard-Radcliffe Veritones of Harvard College where she had the solo on Only You by Yaz.
What is the previous name of oldest recorded college a cappella group?
A: RPI Glee Club

Question: Read this and answer the question

A revolution in 1332 resulted in a broad-based city government with participation of the guilds, and Strasbourg declared itself a free republic. The deadly bubonic plague of 1348 was followed on 14 February 1349 by one of the first and worst pogroms in pre-modern history: over a thousand Jews were publicly burnt to death, with the remainder of the Jewish population being expelled from the city. Until the end of the 18th century, Jews were forbidden to remain in town after 10 pm. The time to leave the city was signalled by a municipal herald blowing the Gruselhorn (see below, Museums, Musee historique);. A special tax, the Pflastergeld (pavement money), was furthermore to be paid for any horse that a Jew would ride or bring into the city while allowed to.

How many Jews were burned to death in 1349?
Answer: over a thousand
