The language was first introduced in North America when Russian explorers voyaged into Alaska and claimed it for Russia during the 1700s. Although most colonists left after the United States bought the land in 1867, a handful stayed and preserved the Russian language in this region to this day, although only a few elderly speakers of this unique dialect are left. Sizable Russian-speaking communities also exist in North America, especially in large urban centers of the U.S. and Canada, such as New York City, Philadelphia, Boston, Los Angeles, Nashville, San Francisco, Seattle, Spokane, Toronto, Baltimore, Miami, Chicago, Denver and Cleveland. In a number of locations they issue their own newspapers, and live in ethnic enclaves (especially the generation of immigrants who started arriving in the early 1960s). Only about 25% of them are ethnic Russians, however. Before the dissolution of the Soviet Union, the overwhelming majority of Russophones in Brighton Beach, Brooklyn in New York City were Russian-speaking Jews. Afterward, the influx from the countries of the former Soviet Union changed the statistics somewhat, with ethnic Russians and Ukrainians immigrating along with some more Russian Jews and Central Asians. According to the United States Census, in 2007 Russian was the primary language spoken in the homes of over 850,000 individuals living in the United States.

Despite leveling after 1900, especially in matters of vocabulary and phonetics, a number of dialects still exist in Russia. Some linguists divide the dialects of Russian into two primary regional groupings, "Northern" and "Southern", with Moscow lying on the zone of transition between the two. Others divide the language into three groupings, Northern, Central (or Middle) and Southern, with Moscow lying in the Central region. All dialects also divided in two main chronological categories: the dialects of primary formation (the territory of the Eastern Rus' or Muscovy, roughly consists of the modern Central and Northwestern Federal districts); and secondary formation (other territory). Dialectology within Russia recognizes dozens of smaller-scale variants. The dialects often show distinct and non-standard features of pronunciation and intonation, vocabulary and grammar. Some of these are relics of ancient usage now completely discarded by the standard language.

Q1: What two regions do some linguists divide Russian into?
A1: "Northern" and "Southern"
Q2: What three regions do some linguists divide Russian into?
A2: Northern, Central (or Middle) and Southern
Q3: What distinguishes Russian dialects?
A3: non-standard features of pronunciation and intonation, vocabulary and grammar
The Northern Russian dialects and those spoken along the Volga River typically pronounce unstressed /o/ clearly (the phenomenon called okanye/оканье). Besides the absence of vowel reduction, some dialects have high or diphthongal /e~i̯ɛ/ in the place of Proto-Slavic *ě and /o~u̯ɔ/ in stressed closed syllables (as in Ukrainian) instead of Standard Russian /e/ and /o/. An interesting morphological feature is a post-posed definite article -to, -ta, -te similarly to that existing in Bulgarian and Macedonian.

Q1: What is okanye?
A1: pronounce unstressed /o/ clearly
Q2: What articles are similar to Bulgarian?
A2: post-posed definite article -to, -ta, -te
Q3: What do some Russian dialects do about vowels?
A3: absence of vowel reduction
Q4: What region of dialects is the Volga River area in?
A4: Northern Russian
In the Southern Russian dialects, instances of unstressed /e/ and /a/ following palatalized consonants and preceding a stressed syllable are not reduced to [ɪ] (as occurs in the Moscow dialect), being instead pronounced [a] in such positions (e.g. несли is pronounced [nʲaˈslʲi], not [nʲɪsˈlʲi]) – this is called yakanye/яканье. Consonants include a fricative /ɣ/, a semivowel /w~u̯/ and /x~xv~xw/, whereas the Standard and Northern dialects have the consonants /ɡ/, /v/, and final /l/ and /f/, respectively. The morphology features a palatalized final /tʲ/ in 3rd person forms of verbs (this is unpalatalized in the Standard and Northern dialects). Some of these features such as akanye/yakanye, a debuccalized or lenited /ɡ/, a semivowel /w~u̯/ and palatalized final /tʲ/ in 3rd person forms of verbs are also present in modern Belarusian and some dialects of Ukrainian (Eastern Polesian), indicating a linguistic continuum.

Q1: What is pronounced [ɪ] in Moscow's dialect?
A1: unstressed /e/ and /a/ following palatalized consonants and preceding a stressed syllable
Q2: What is pronounced [a] in Southern Russian?
A2: unstressed /e/ and /a/ following palatalized consonants and preceding a stressed syllable
Q3: What does Southern Russian have a linguistic continuum with?
A3: modern Belarusian and some dialects of Ukrainian (Eastern Polesian)
Among the first to study Russian dialects was Lomonosov in the 18th century. In the 19th, Vladimir Dal compiled the first dictionary that included dialectal vocabulary. Detailed mapping of Russian dialects began at the turn of the 20th century. In modern times, the monumental Dialectological Atlas of the Russian Language (Диалектологический атлас русского языка [dʲɪɐˌlʲɛktəlɐˈɡʲitɕɪskʲɪj ˈatləs ˈruskəvə jɪzɨˈka]), was published in three folio volumes 1986–1989, after four decades of preparatory work.

Older letters of the Russian alphabet include ⟨ѣ⟩, which merged to ⟨е⟩ (/je/ or /ʲe/); ⟨і⟩ and ⟨ѵ⟩, which both merged to ⟨и⟩ (/i/); ⟨ѳ⟩, which merged to ⟨ф⟩ (/f/); ⟨ѫ⟩, which merged to ⟨у⟩ (/u/); ⟨ѭ⟩, which merged to ⟨ю⟩ (/ju/ or /ʲu/); and ⟨ѧ/⟨ѩ⟩⟩, which later were graphically reshaped into ⟨я⟩ and merged phonetically to /ja/ or /ʲa/. While these older letters have been abandoned at one time or another, they may be used in this and related articles. The yers ⟨ъ⟩ and ⟨ь⟩ originally indicated the pronunciation of ultra-short or reduced /ŭ/, /ĭ/.

Because of many technical restrictions in computing and also because of the unavailability of Cyrillic keyboards abroad, Russian is often transliterated using the Latin alphabet. For example, мороз ('frost') is transliterated moroz, and мышь ('mouse'), mysh or myš'. Once commonly used by the majority of those living outside Russia, transliteration is being used less frequently by Russian-speaking typists in favor of the extension of Unicode character encoding, which fully incorporates the Russian alphabet. Free programs leveraging this Unicode extension are available which allow users to type Russian characters, even on Western 'QWERTY' keyboards.

Q1: What is 'moroz' a transliteration of?
A1: мороз
Q2: What is 'mysh' a transliteration of?
A2: мышь
Q3: What does 'moroz' mean?
A3: frost
Q4: What font technology has reduced the need for transliteration?
A4: Unicode character encoding,
Q5: What does 'mysh' mean?
A5: mouse
The Russian alphabet has many systems of character encoding. KOI8-R was designed by the Soviet government and was intended to serve as the standard encoding. This encoding was and still is widely used in UNIX-like operating systems. Nevertheless, the spread of MS-DOS and OS/2 (IBM866), traditional Macintosh (ISO/IEC 8859-5) and Microsoft Windows (CP1251) created chaos and ended by establishing different encodings as de facto standards, with Windows-1251 becoming a de facto standard in Russian Internet and e-mail communication during the period of roughly 1995–2005.

Q1: Who created KOI8-R encoding?
A1: the Soviet government
Q2: What system used CP1251 encoding?
A2: Microsoft Windows
Q3: What systems used IBM866 encoding?

According to the Institute of Russian Language of the Russian Academy of Sciences, an optional acute accent (знак ударения) may, and sometimes should, be used to mark stress. For example, it is used to distinguish between otherwise identical words, especially when context does not make it obvious: замо́к/за́мок (lock/castle), сто́ящий/стоя́щий (worthwhile/standing), чудно́/чу́дно (this is odd/this is marvelous), молоде́ц/мо́лодец (attaboy/fine young man), узна́ю/узнаю́ (I shall learn it/I recognize it), отреза́ть/отре́зать (to be cutting/to have cut); to indicate the proper pronunciation of uncommon words, especially personal and family names (афе́ра, гу́ру, Гарси́я, Оле́ша, Фе́рми), and to show which is the stressed word in a sentence (Ты́ съел печенье?/Ты съе́л печенье?/Ты съел пече́нье? – Was it you who ate the cookie?/Did you eat the cookie?/Was it the cookie that you ate?). Stress marks are mandatory in lexical dictionaries and books for children or Russian learners.

The language possesses five vowels (or six, under the St. Petersburg Phonological School), which are written with different letters depending on whether or not the preceding consonant is palatalized. The consonants typically come in plain vs. palatalized pairs, which are traditionally called hard and soft. (The hard consonants are often velarized, especially before front vowels, as in Irish). The standard language, based on the Moscow dialect, possesses heavy stress and moderate variation in pitch. Stressed vowels are somewhat lengthened, while unstressed vowels tend to be reduced to near-close vowels or an unclear schwa. (See also: vowel reduction in Russian.)

Q1: Who says Russian has 6 vowels?
A1: St. Petersburg Phonological School
Q2: When are Russian vowels written differently?
A2: depending on whether or not the preceding consonant is palatalized
Q3: What dialect is standard Russian based on?
A3: Moscow dialect
Q4: What language does Russian treat hard consonants similar to?
A4: Irish
Q5: What is done to unstressed vowels?
A5: reduced to near-close vowels or an unclear schwa
Russian is notable for its distinction based on palatalization of most of the consonants. While /k/, /ɡ/, /x/ do have palatalized allophones [kʲ, ɡʲ, xʲ], only /kʲ/ might be considered a phoneme, though it is marginal and generally not considered distinctive (the only native minimal pair which argues for /kʲ/ to be a separate phoneme is "это ткёт" ([ˈɛtə tkʲɵt], 'it weaves')/"этот кот" ([ˈɛtət kot], 'this cat')). Palatalization means that the center of the tongue is raised during and after the articulation of the consonant. In the case of /tʲ/ and /dʲ/, the tongue is raised enough to produce slight frication (affricate sounds). These sounds: /t, d, ts, s, z, n and rʲ/ are dental, that is pronounced with the tip of the tongue against the teeth rather than against the alveolar ridge.

Q1: What might /kʲ/ be considered?
A1: a phoneme
Q2: What is palatalization?
A2: the center of the tongue is raised during and after the articulation of the consonant
Q3: How are 'dental' sounds pronounced?
A3: with the tip of the tongue against the teeth rather than against the alveolar ridge
Judging by the historical records, by approximately 1000 AD the predominant ethnic group over much of modern European Russia, Ukraine and Belarus was the Eastern branch of the Slavs, speaking a closely related group of dialects. The political unification of this region into Kievan Rus' in about 880, from which modern Russia, Ukraine and Belarus trace their origins, established Old East Slavic as a literary and commercial language. It was soon followed by the adoption of Christianity in 988 and the introduction of the South Slavic Old Church Slavonic as the liturgical and official language. Borrowings and calques from Byzantine Greek began to enter the Old East Slavic and spoken dialects at this time, which in their turn modified the Old Church Slavonic as well.

A1: approximately 1000 AD
Q2: When was Kievan Rus' formed?
A2: about 880

The political reforms of Peter the Great (Пётр Вели́кий, Pyótr Velíkiy) were accompanied by a reform of the alphabet, and achieved their goal of secularization and Westernization. Blocks of specialized vocabulary were adopted from the languages of Western Europe. By 1800, a significant portion of the gentry spoke French daily, and German sometimes. Many Russian novels of the 19th century, e.g. Leo Tolstoy's (Лев Толсто́й) War and Peace, contain entire paragraphs and even pages in French with no translation given, with an assumption that educated readers would not need one.

Q2: What second language was common among Russian nobles by 1800?
A2: French
Q3: What third language was common among Russian nobles by 1800?
A3: German

The modern literary language is usually considered to date from the time of Alexander Pushkin (Алекса́ндр Пу́шкин) in the first third of the 19th century. Pushkin revolutionized Russian literature by rejecting archaic grammar and vocabulary (so-called "высо́кий стиль" — "high style") in favor of grammar and vocabulary found in the spoken language of the time. Even modern readers of younger age may only experience slight difficulties understanding some words in Pushkin's texts, since relatively few words used by Pushkin have become archaic or changed meaning. In fact, many expressions used by Russian writers of the early 19th century, in particular Pushkin, Mikhail Lermontov (Михаи́л Ле́рмонтов), Nikolai Gogol (Никола́й Го́голь), Aleksander Griboyedov (Алекса́ндр Грибое́дов), became proverbs or sayings which can be frequently found even in modern Russian colloquial speech.

A1: Alexander Pushkin
Q2: What did Pushkin reject from older Russian?
A2: archaic grammar and vocabulary
Q3: What was 'high style'?

A4: became proverbs or sayings which can be frequently found even in modern Russian colloquial speech
During the Soviet period, the policy toward the languages of the various other ethnic groups fluctuated in practice. Though each of the constituent republics had its own official language, the unifying role and superior status was reserved for Russian, although it was declared the official language only in 1990. Following the break-up of the USSR in 1991, several of the newly independent states have encouraged their native languages, which has partly reversed the privileged status of Russian, though its role as the language of post-Soviet national discourse throughout the region has continued.

Q1: When did the USSR dissolve?
A1: 1991
Q2: When did the USSR make Russian the official language?
A2: 1990
Q3: What unofficial status did Russian have in the USSR before 1990?

According to figures published in 2006 in the journal "Demoskop Weekly" research deputy director of Research Center for Sociological Research of the Ministry of Education and Science (Russia) Arefyev A. L., the Russian language is gradually losing its position in the world in general, and in Russia in particular. In 2012, A. L. Arefyev published a new study "Russian language at the turn of the 20th-21st centuries", in which he confirmed his conclusion about the trend of further weakening of the Russian language in all regions of the world (findings published in 2013 in the journal "Demoskop Weekly"). In the countries of the former Soviet Union the Russian language is gradually being replaced by local languages. Currently the number speakers of Russian language in the world depends on the number of Russians in the world (as the main sources distribution Russian language) and total population Russia (where Russian is an official language).

The U.S. Air Force is a military service organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force is headed by the civilian Secretary of the Air Force, who reports to the Secretary of Defense, and is appointed by the President with Senate confirmation. The highest-ranking military officer in the Department of the Air Force is the Chief of Staff of the Air Force, who exercises supervision over Air Force units, and serves as a member of the Joint Chiefs of Staff. Air Force combat and mobility forces are assigned, as directed by the Secretary of Defense, to the Combatant Commanders, and neither the Secretary of the Air Force nor the Chief of Staff have operational command authority over them.

Recently, the Air Force refined its understanding of the core duties and responsibilities it performs as a Military Service Branch, streamlining what previously were six distinctive capabilities and seventeen operational functions into twelve core functions to be used across the doctrine, organization, training, equipment, leadership, and education, personnel, and facilities spectrum. These core functions express the ways in which the Air Force is particularly and appropriately suited to contribute to national security, but they do not necessarily express every aspect of what the Air Force contributes to the nation. It should be emphasized that the core functions, by themselves, are not doctrinal constructs.

Q1: How many core functions did the Air Force reduce its duties down to recently?
A1: twelve
Q2: What do these core functions of the Air Force express?
A2: contribute to national security
Q3: What are not considered doctrinal constructs of the Air Force?
