Document 2: Iranian languages: It is possible that other distinct dialect groups were already in existence during this period. Good candidates are the hypothethical ancestor languages of Alanian/Scytho-Sarmatian subgroup of Scythian in the far northwest; and the hypothetical "Old Parthian" (the Old Iranian ancestor of Parthian) in the near northwest, where original *dw > *b (paralleling the development of *ćw).
Document 3: Iranian languages: The multitude of Middle Iranian languages and peoples indicate that great linguistic diversity must have existed among the ancient speakers of Iranian languages. Of that variety of languages/dialects, direct evidence of only two have survived. These are:
Document 4: Zīnah al-Sādāt Humāyūnī: When Banu Amin opened one of the country's first religious seminary for women in Iran in the 1960s, the Maktab-e Fatimah of Isfahan, Zīnah al-Sādāt Humāyūnī became its director and remained in that position until 1992.

Document 5: Godwin Chepkurgor: In 2009, another Kenyan journalist brought up the subject of the 2000 marriage proposal to then U.S. Secretary of State Hillary Clinton during a town hall meeting with reporters.

Document 6: Iranian languages: Old Persian is the Old Iranian dialect as it was spoken in south-western Iran by the inhabitants of Parsa, who also gave their name to their region and language. Genuine Old Persian is best attested in one of the three languages of the Behistun inscription, composed circa 520 BC, and which is the last inscription (and only inscription of significant length) in which Old Persian is still grammatically correct. Later inscriptions are comparatively brief, and typically simply copies of words and phrases from earlier ones, often with grammatical errors, which suggests that by the 4th century BC the transition from Old Persian to Middle Persian was already far advanced, but efforts were still being made to retain an "old" quality for official proclamations.
Document 7: Western Iranian languages: The Western Iranian languages are a branch of the Iranian languages, attested from the time of Old Persian (6th century BC) and Median.

Document 10: Iranian languages: In addition to Old Persian and Avestan, which are the only directly attested Old Iranian languages, all Middle Iranian languages must have had a predecessor "Old Iranian" form of that language, and thus can all be said to have had an (at least hypothetical) "Old" form. Such hypothetical Old Iranian languages include Carduchi (the hypothetical predecessor to Kurdish) and Old Parthian. Additionally, the existence of unattested languages can sometimes be inferred from the impact they had on neighbouring languages. Such transfer is known to have occurred for Old Persian, which has (what is called) a "Median" substrate in some of its vocabulary. Also, foreign references to languages can also provide a hint to the existence of otherwise unattested languages, for example through toponyms/ethnonyms or in the recording of vocabulary, as Herodotus did for what he called "Scythian".
Document 11: Maryam Mahboob: Following the Russian occupation of Afghanistan in 1979, Mahboob left the country to move first to Pakistan, and then to Delhi, India in 1981. Along with other Afghan expatriates, Mahboob started the journal "Gahnama" ("irregular journal") to express cultural resistance against both the communist government of Afghanistan and the Mujahideen. However, facing pressure from the Mujahideen amongst the Afghan community in India, she migrated once again to move to Canada in 1983.

According to "The New York Times", three women wearing the niqāb and abaya entered the mall and unfurled a banner reading, "It is forbidden to arbitrarily arrest and detain people". More than a dozen plain-clothes and uniformed police officers surrounded them, and Fakhria al-Singace was handcuffed and arrested after being pinned spread-eagled to a cafe table.
