Question: The old version of the language Saboktakin Saloor speaks is part of what family of languages?

full_context: Document 1: Salvador Novo: Salvador Novo López (30 July 1904 – 13 January 1974) was a Mexican writer, poet, playwright, translator, television presenter, entrepreneur, and the official chronicler of Mexico City. As a noted intellectual, he influenced popular perceptions of politics, media, the arts, and Mexican society in general. He was a member of Los Contemporáneos, a group of Mexican writers, as well as of the Mexican Academy of the Language.
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: Saboktakin Saloor: Saboktakin Saloor (October 26, 1923 - November 8, 1991) was a Persian journalist and historical novelist. He also wrote many popular serialized radio and television programs.
Document 4: Iranian languages: What is known in Iranian linguistic history as the "Middle Iranian" era is thought to begin around the 4th century BCE lasting through the 9th century. Linguistically the Middle Iranian languages are conventionally classified into two main groups, Western and Eastern.
Document 5: Sarmad Kashani: Sarmad Kashani or simply as "Sarmad" (ca 1590–1661) was a Persian speaking Armenian mystic and poet who travelled to and made the Indian subcontinent his permanent home during the 17th century. Originally Jewish, he may have renounced his religion to adopt Islam. Sarmad, in his poetry, states that he is neither Jewish, nor Muslim, nor Hindu.
Document 6: Iranian languages: Two of the earliest dialectal divisions among Iranian indeed happen to not follow the later division into Western and Eastern blocks. These concern the fate of the Proto-Indo-Iranian first-series palatal consonants, *ć and *dź:
Document 7: Amir Jan Sabori: Amir Jan Sabori () is a singer, musician, composer, and poet from Herat, Afghanistan. There is a documentary about him called "Golden Dream". Amir Jan Sabori had a long hiatus in his career but returned in 2005 with his album "This Is Life". He is also the uncle of emerging singer Tawab Arash and has done production for him.
Document 8: Iranian languages: The other directly attested Old Iranian dialects are the two forms of Avestan, which take their name from their use in the Avesta, the liturgical texts of indigenous Iranian religion that now goes by the name of Zoroastrianism but in the Avesta itself is simply known as vohu daena (later: behdin). The language of the Avesta is subdivided into two dialects, conventionally known as "Old (or 'Gathic') Avestan", and "Younger Avestan". These terms, which date to the 19th century, are slightly misleading since 'Younger Avestan' is not only much younger than 'Old Avestan', but also from a different geographic region. The Old Avestan dialect is very archaic, and at roughly the same stage of development as Rigvedic Sanskrit. On the other hand, Younger Avestan is at about the same linguistic stage as Old Persian, but by virtue of its use as a sacred language retained its "old" characteristics long after the Old Iranian languages had yielded to their Middle Iranian stage. Unlike Old Persian, which has Middle Persian as its known successor, Avestan has no clearly identifiable Middle Iranian stage (the effect of Middle Iranian is indistinguishable from effects due to other causes).
Document 9: Wahbi al-Bouri: Wahbi El-Bouri was an accomplished writer and is considered by many to be the father of the short story genre in Libya. He also wrote essays and other works of non-fiction on history and politics. He also translated a number of books in Italian about Libya. After his death Dr El-Bouri continued to be a character of inspiration for many Libyans to learn from his lifetime experience in Public Service as he served his country for almost 85 years and the numerous books he left behind, in 2011 after the Libyan uprising his family published his biography “Memories of my life”. In Jan 2017 El- Bouri’s grandson Zeid Basyouni and the El-Bouri family announced the establishment of the El-Bouri Foundation to continue Wahbi El-Bouri’s legacy as manifest in his great generosity of spirit which remained his trait up and aims to encourage and support young minds in the field of Writing, Literature, Public Service and Leadership.
Document 10: 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 11: Hadi al-Mahdi: "The New York Times", which wrote a profile on him one year before he was killed, compared him to Rush Limbaugh in his visibility and impact: "arguably the most breathtaking exercise of free speech in a place where its limits are still being established. It is, by some accounts, one of the most popular programs on the air in Baghdad. It is, without question, immensely entertaining."
Document 12: 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 13: 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 14: 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 15: Mohammad Hejazi (author): Mohammad Hejazi (محمد حجازی; in Persian) (April 14, 1900–January 30, 1974) was an Iranian novelist, short-story writer, playwright, essayist, translator, a government official and member of the senate.
