Problem: Please answer a question about the following article about Carnival:
Traditionally a carnival feast was the last opportunity to eat well before the time of food shortage at the end of the winter during which one was limited to the minimum necessary. On what nowadays is called vastenavond (the days before fasting) all the remaining winter stores of lard, butter and meat which were left would be eaten, for it would soon start to rot and decay. The selected livestock had in fact already been slaughtered in November and the meat would be no longer preservable. All the food that had survived the winter had to be eaten to assure that everyone was fed enough to survive until the coming spring would provide new food sources.
Why was the carnival feast typically the last opportunity to eat well?
A: food shortage at the end of the winter

Tonearm skating forces and other perturbations are also picked up by the stylus. This is a form of frequency multiplexing as the control signal (restoring force) used to keep the stylus in the groove is carried by the same mechanism as the sound itself. Subsonic frequencies below about 20 Hz in the audio signal are dominated by tracking effects, which is one form of unwanted rumble ("tracking noise") and merges with audible frequencies in the deep bass range up to about 100 Hz. High fidelity sound equipment can reproduce tracking noise and rumble. During a quiet passage, woofer speaker cones can sometimes be seen to vibrate with the subsonic tracking of the stylus, at frequencies as low as just above 0.5 Hz (the frequency at which a 33 1⁄3 rpm record turns on the turntable; 5⁄9 Hz exactly on an ideal turntable). Another reason for very low frequency material can be a warped disk: its undulations produce frequencies of only a few hertz and present day amplifiers have large power bandwidths. For this reason, many stereo receivers contained a switchable subsonic filter. Some subsonic content is directly out of phase in each channel. If played back on a mono subwoofer system, the noise will cancel, significantly reducing the amount of rumble that is reproduced.

What is a feature many stereos contain to fight back against unwanted noises?
Answer: subsonic filter


Problem: In 1568, Spanish navigator Álvaro de Mendaña was the first European to sail through the archipelago, sighting the island of Nui during his expedition in search of Terra Australis. In 1819 the island of Funafuti was named Ellice's Island; the name Ellice was applied to all nine islands after the work of English hydrographer Alexander George Findlay. The islands came under Britain's sphere of influence in the late 19th century, when each of the Ellice Islands was declared a British Protectorate by Captain Gibson of HMS Curacoa between 9 and 16 October 1892. The Ellice Islands were administered as British protectorate by a Resident Commissioner from 1892 to 1916 as part of the British Western Pacific Territories (BWPT), and then as part of the Gilbert and Ellice Islands colony from 1916 to 1974.
What land mass was de Mendana actually seeking?
The answer is the following: Terra Australis


To prevent piracy of films, the standard drill of film distribution is to have a movie first released through movie theaters (theatrical window), on average approximately 16 and a half weeks, before having it released to Blu-Ray and DVD (entering its video window). During the theatrical window, digital versions of films are often transported in data storage devices by couriers rather than by data transmission. The data can be encrypted, with the key being made to work only at specific times in order to prevent leakage between screens. Coded Anti-Piracy marks can be added to films to identify the source of illegal copies and shut them down. As a result of these measures, the only versions of films available for piracy during the theatrical window are usually "cams" made by video recordings of the movie screens, which are of inferior quality compared to the original film version.
During this time, how are digital versions of the movie transported in data storage devices?
by couriers


Input: Russian Soviet Federative Socialist Republic
The Russian Soviet Federative Socialist Republic (Russian SFSR or RSFSR; Russian: Российская Советская Федеративная Социалистическая Республика, tr. Rossiyskaya Sovetskaya Federativnaya Sotsialisticheskaya Respublika  listen (help·info)) commonly referred to as Soviet Russia or simply as Russia, was a sovereign state in 1917–22, the largest, most populous, and most economically developed republic of the Soviet Union in 1922–91 and a sovereign part of the Soviet Union with its own legislation in 1990–91. The Republic comprised sixteen autonomous republics, five autonomous oblasts, ten autonomous okrugs, six krais, and forty oblasts. Russians formed the largest ethnic group. To the west it bordered Finland, Norway and Poland; and to the south, China, Mongolia and North Korea whilst bordering the Arctic Ocean to the north, the Pacific Ocean to the east and the Black sea and Caspian Sea to the south. Within the USSR, it bordered the Baltic republics (Lithuania, Latvia and Estonia), the Byelorussian SSR and the Ukrainian SSR to the west. To the south it bordered the Georgian, Azerbaijan and Kazakh SSRs.

How many krais were present in the RSFSR?
Output: six


Problem: Please answer a question about the following article about Boston:
As of 2010 the Catholic Church had the highest number of adherents as a single denomination in the Boston-Cambridge-Newton Metro area, with more than two million members and 339 churches, followed by the Episcopal Church with 58,000 adherents in 160 churches. The United Church of Christ had 55,000 members and 213 churches. The UCC is the successor of the city's Puritan religious traditions. Old South Church in Boston is one of the oldest congregations in the United States. It was organized in 1669 by dissenters from the First Church in Boston (1630). Notable past members include Samuel Adams, William Dawes, Benjamin Franklin, Samuel Sewall, and Phillis Wheatley.
