Problem: Gramophone record:

A different format, CD-4 (not to be confused with compact disc), by RCA, encoded the front-rear difference information on an ultrasonic carrier, which required a special wideband cartridge to capture it on carefully calibrated pickup arm/turntable combinations. CD-4 was even less successful than the two matrixed formats. (A further problem was that no cutting heads were available that could handle the HF information. That was remedied by cutting at half the speed. Later, the special half-speed cutting heads and equalization techniques were employed to get a wider frequency response in stereo with reduced distortion and greater headroom.)

What format was less successful than quadraphonic?
---
A: CD-4


Problem: The original charter of the Province of East Jersey had restricted membership in the Assembly to Christians; the Duke of York was fervently Catholic, and the proprietors of Perth Amboy, New Jersey were Scottish Catholic peers. The Province of West Jersey had declared, in 1681, that there should be no religious test for office. An oath had also been imposed on the militia during the French and Indian War requiring them to abjure the pretensions of the Pope, which may or may not have been applied during the Revolution. That law was replaced by 1799.
What religious sect were the proprietors of Perth Amboy?
---
Answer: Scottish Catholic


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1816, François Magendie discovered that dogs fed only carbohydrates (sugar), fat (olive oil), and water died evidently of starvation, but dogs also fed protein survived, identifying protein as an essential dietary component. William Prout in 1827 was the first person to divide foods into carbohydrates, fat, and protein. During the 19th century, Jean-Baptiste Dumas and Justus von Liebig quarrelled over their shared belief that animals get their protein directly from plants (animal and plant protein are the same and that humans do not create organic compounds). With a reputation as the leading organic chemist of his day but with no credentials in animal physiology, Liebig grew rich making food extracts like beef bouillon and infant formula that were later found to be of questionable nutritious value. In the 1860s, Claude Bernard discovered that body fat can be synthesized from carbohydrate and protein, showing that the energy in blood glucose can be stored as fat or as glycogen.
Which dietary component was not fed to dogs resulting in their death?
A: protein


Context and question: However a log-periodic dipole array consists of a number of dipole elements of different lengths in order to obtain a somewhat directional antenna having an extremely wide bandwidth: these are frequently used for television reception in fringe areas. The dipole antennas composing it are all considered "active elements" since they are all electrically connected together (and to the transmission line). On the other hand, a superficially similar dipole array, the Yagi-Uda Antenna (or simply "Yagi"), has only one dipole element with an electrical connection; the other so-called parasitic elements interact with the electromagnetic field in order to realize a fairly directional antenna but one which is limited to a rather narrow bandwidth. The Yagi antenna has similar looking parasitic dipole elements but which act differently due to their somewhat different lengths. There may be a number of so-called "directors" in front of the active element in the direction of propagation, and usually a single (but possibly more) "reflector" on the opposite side of the active element.
What type of antenna formation is made up of multiple dipole elements of varying lengths?
Answer: log-periodic dipole array


Question: From earliest days, Virginia, and Richmond in particular, have welcomed live theatrical performances. From Lewis Hallam's early productions of Shakespeare in Williamsburg, the focus shifted to Richmond's antebellum prominence as a main colonial and early 19th century performance venue for such celebrated American and English actors as William Macready, Edwin Forrest, and the Booth family. In the 20th century, Richmonders' love of theater continued with many amateur troupes and regular touring professional productions. In the 1960s a small renaissance or golden age accompanied the growth of professional dinner theaters and the fostering of theater by the Virginia Museum, reaching a peak in the 1970s with the establishment of a resident Equity company at the Virginia Museum Theater (now the Leslie Cheek) and the birth of Theatre IV, a company that continues to this day.
Is there an answer to this question: In what city did Lewis Hallam present Shakespeare's plays?

Answer: Williamsburg


QUES: Outside of the Netherlands and Belgium, the dialect around the German town of Kleve (South Guelderish) both historically and genetically belongs to the Dutch language. In Northeastern France, the area around Calais was historically Dutch-speaking (West Flemish) of which an estimated 20,000 daily speakers. The cities of Dunkirk, Gravelines and Bourbourg only became predominantly French-speaking by the end of the 19th century. In the countryside, until World War I, many elementary schools continued to teach in Dutch, and the Catholic Church continued to preach and teach the catechism in Flemish in many parishes.

It took until the end of what century for people in French cities like Gravelines to finally switch over to French from Dutch?
What is the answer?
ANS:
