In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Q: What is the official name for the soldier's specialized area of expertise?, Context: Training in the U.S. Army is generally divided into two categories – individual and collective. Basic training consists of 10 weeks for most recruits followed by Advanced Individualized Training (AIT) where they receive training for their military occupational specialties (MOS). Some individuals MOSs range anywhere from 14–20 weeks of One Station Unit Training (OSUT), which combines Basic Training and AIT. The length of AIT school varies by the MOS The length of time spent in AIT depends on the MOS of the soldier, and some highly technical MOS training may require many months (e.g., foreign language translators). Depending on the needs of the army, Basic Combat Training for combat arms soldiers is conducted at a number of locations, but two of the longest-running are the Armor School and the Infantry School, both at Fort Benning, Georgia.

A: military occupational specialties (MOS)

Q: How can you reduce the jnd?, 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.

A: two tones are played simultaneously

Q: How was it determined that younger people are less likely to consider Valencian different than Catalan?, Context: Despite the position of the official organizations, an opinion poll carried out between 2001 and 2004 showed that the majority of the Valencian people consider Valencian different from Catalan. This position is promoted by people who do not use Valencian regularly. Furthermore, the data indicates that younger generations educated in Valencian are much less likely to hold these views. A minority of Valencian scholars active in fields other than linguistics defends the position of the Royal Academy of Valencian Culture (Acadèmia de Cultura Valenciana, RACV), which uses for Valencian a standard independent from Catalan.

A:
an opinion poll
