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

[EX 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.
[EX A]: military occupational specialties (MOS)

[EX Q]: Which trade route connected Northern Europe and Northwestern Russia with the Capsian Sea?, Context: The new Kievan state prospered due to its abundant supply of furs, beeswax, honey, and slaves for export, and because it controlled three main trade routes of Eastern Europe. In the north, Novgorod served as a commercial link between the Baltic Sea and the Volga trade route to the lands of the Volga Bulgars, the Khazars, and across the Caspian Sea as far as Baghdad, providing access to markets and products from Central Asia and the Middle East. Trade from the Baltic also moved south on a network of rivers and short portages along the Dnieper known as the "route from the Varangians to the Greeks," continuing to the Black Sea and on to Constantinople. Kiev was a central outpost along the Dnieper route and a hub with the east-west overland trade route between the Khazars and the Germanic lands of Central Europe. These commercial connections enriched Rus' merchants and princes, funding military forces and the construction of churches, palaces, fortifications, and further towns. Demand for luxury goods fostered production of expensive jewelry and religious wares, allowing their export, and an advanced credit and money-lending system may have also been in place.
[EX A]: Volga trade route

[EX Q]: What does "identity"mean?, Context: The description or representation of individual and group identity is a central task for psychologists, sociologists and anthropologists and those of other disciplines where "identity" needs to be mapped and defined. How should one describe the identity of another, in ways which encompass both their idiosyncratic qualities and their group memberships or identifications, both of which can shift according to circumstance? Following on from the work of Kelly, Erikson, Tajfel and others Weinreich's Identity Structure Analysis (ISA), is "a structural representation of the individual's existential experience, in which the relationships between self and other agents are organised in relatively stable structures over time … with the emphasis on the socio-cultural milieu in which self relates to other agents and institutions" (Weinreich and Saunderson, (eds) 2003, p1). Using constructs drawn from the salient discourses of the individual, the group and cultural norms, the practical operationalisation of ISA provides a methodology that maps how these are used by the individual, applied across time and milieus by the "situated self" to appraise self and other agents and institutions (for example, resulting in the individual's evaluation of self and significant others and institutions).[citation needed]
