Input: Sino-Tibetan relations during the Ming dynasty
According to Tibetologist John Powers, Tibetan sources counter this narrative of titles granted by the Chinese to Tibetans with various titles which the Tibetans gave to the Chinese emperors and their officials. Tribute missions from Tibetan monasteries to the Chinese court brought back not only titles, but large, commercially valuable gifts which could subsequently be sold. The Ming emperors sent invitations to ruling lamas, but the lamas sent subordinates rather than coming themselves, and no Tibetan ruler ever explicitly accepted the role of being a vassal of the Ming.

What was the name of the Tibetologist?
Output: John Powers

Input: Professional wrestling
In Latin America and English-speaking countries, most wrestlers (and other on-stage performers) portray character roles, sometimes with personalities wildly different from their own. These personalities are a gimmick intended to heighten interest in a wrestler without regard to athletic ability. Some can be unrealistic and cartoon-like (such as Doink the Clown), while others carry more verisimilitude and can be seen as exaggerated versions of the performer's real life personality (such as Chris Jericho, The Rock, John Cena, Stone Cold Steve Austin, and CM Punk). In lucha libre, many characters wear masks, adopting a secret identity akin to a superhero, a near-sacred tradition.

What is common apparel in lucha libre?
