Input: Article: Conventionally, Iranian languages are grouped in "western" and "eastern" branches. These terms have little meaning with respect to Old Avestan as that stage of the language may predate the settling of the Iranian peoples into western and eastern groups. The geographic terms also have little meaning when applied to Younger Avestan since it isn't known where that dialect (or dialects) was spoken either. Certain is only that Avestan (all forms) and Old Persian are distinct, and since Old Persian is "western", and Avestan was not Old Persian, Avestan acquired a default assignment to "eastern". Confusing the issue is the introduction of a western Iranian substrate in later Avestan compositions and redactions undertaken at the centers of imperial power in western Iran (either in the south-west in Persia, or in the north-west in Nisa/Parthia and Ecbatana/Media).

Now answer this question: Which language is associated with the eastern branch of Iranian?

Output: Avestan

Input: Article: Emotion regulation refers to the cognitive and behavioral strategies people use to influence their own emotional experience. For example, a behavioral strategy in which one avoids a situation to avoid unwanted emotions (e.g., trying not to think about the situation, doing distracting activities, etc.). Depending on the particular school's general emphasis on either cognitive components of emotion, physical energy discharging, or on symbolic movement and facial expression components of emotion, different schools of psychotherapy approach the regulation of emotion differently. Cognitively oriented schools approach them via their cognitive components, such as rational emotive behavior therapy. Yet others approach emotions via symbolic movement and facial expression components (like in contemporary Gestalt therapy).

Now answer this question: Rational emotive behavior therapy is an approach used by what psychotherapy schools?

Output: Cognitively oriented schools

Input: Article: In 2014 artist Jack White sold 40,000 copies of his second solo release, Lazaretto, on vinyl. The sales of the record beat the largest sales in one week on vinyl since 1991. The sales record was previously held by Pearl Jam's, Vitalogy, which sold 34,000 copies in one week in 1994.
