Please answer this: Extract the answer to the question from the following context. Question: What was expanded during the 51st year of the 1900s? Context: In 1922, the number of supporters had surpassed 20,000 and by lending money to the club, Barca was able to build the larger Camp de Les Corts, which had an initial capacity of 20,000 spectators. After the Spanish Civil War the club started attracting more members and a larger number of spectators at matches. This led to several expansion projects: the grandstand in 1944, the southern stand in 1946, and finally the northern stand in 1950. After the last expansion, Les Corts could hold 60,000 spectators.

Answer: the northern stand

Problem: Extract the answer to the question from the following context. Question: In rare instances, which shapes may you find some bacteria to be? Context: Most bacterial species are either spherical, called cocci (sing. coccus, from Greek kokkos, grain, seed), or rod-shaped, called bacilli (sing. bacillus, from Latin baculus, stick). Elongation is associated with swimming. Some bacteria, called vibrio, are shaped like slightly curved rods or comma-shaped; others can be spiral-shaped, called spirilla, or tightly coiled, called spirochaetes. A small number of species even have tetrahedral or cuboidal shapes. More recently, some bacteria were discovered deep under Earth's crust that grow as branching filamentous types with a star-shaped cross-section. The large surface area to volume ratio of this morphology may give these bacteria an advantage in nutrient-poor environments. This wide variety of shapes is determined by the bacterial cell wall and cytoskeleton, and is important because it can influence the ability of bacteria to acquire nutrients, attach to surfaces, swim through liquids and escape predators.

A: tetrahedral or cuboidal shapes

Problem: Given the question: Extract the answer to the question from the following context. Question: Who was an early supporter of the TGP? Context: During the 20th century, many artists immigrated to Mexico City from different regions of Mexico, such as Leopoldo Mendez, an engraver from Veracruz, who supported the creation of the socialist Taller de la Grafica Popular (Popular Graphics Workshop), designed to help blue-collar workers find a venue to express their art. Other painters came from abroad, such as Catalan painter Remedios Varo and other Spanish and Jewish exiles. It was in the second half of the 20th century that the artistic movement began to drift apart from the Revolutionary theme. Jose Luis Cuevas opted for a modernist style in contrast to the muralist movement associated with social politics.

input question: Extract the answer to the question from the following context. Question: How can the sounds be played in order to make it easier for the listener to differentiate them? Context: The just-noticeable difference (jnd) (the threshold at which a change is perceived) depends on the tone's frequency content. Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if the two tones are played simultaneously as the listener is then able to discern beat frequencies. The total number of perceptible pitch steps in the range of human hearing is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120.???
output answer: simultaneously

Extract the answer to the question from the following context. Question: When was Tajikistan in third place? Context: Drug trafficking is the major illegal source of income in Tajikistan as it is an important transit country for Afghan narcotics bound for Russian and, to a lesser extent, Western European markets; some opium poppy is also raised locally for the domestic market. However, with the increasing assistance from international organizations, such as UNODC, and cooperation with the US, Russian, EU and Afghan authorities a level of progress on the fight against illegal drug-trafficking is being achieved. Tajikistan holds third place in the world for heroin and raw opium confiscations (1216.3 kg of heroin and 267.8 kg of raw opium in the first half of 2006). Drug money corrupts the country's government; according to some experts the well-known personalities that fought on both sides of the civil war and have held the positions in the government after the armistice was signed are now involved in the drug trade. UNODC is working with Tajikistan to strengthen border crossings, provide training, and set up joint interdiction teams. It also helped to establish Tajikistani Drug Control Agency.

Q: Extract the answer to the question from the following context. Question: What genre did Chopin create? Context: Chopin took the new salon genre of the nocturne, invented by the Irish composer John Field, to a deeper level of sophistication. He was the first to write ballades and scherzi as individual concert pieces. He essentially established a new genre with his own set of free-standing preludes (Op. 28, published 1839). He exploited the poetic potential of the concept of the concert etude, already being developed in the 1820s and 1830s by Liszt, Clementi and Moscheles, in his two sets of studies (Op. 10 published in 1833, Op. 25 in 1837).
A:
salon
