[EX Q]: Passage: The 5th Dalai Lama is known for unifying the Tibetan heartland under the control of the Gelug school of Tibetan Buddhism, after defeating the rival Kagyu and Jonang sects and the secular ruler, the Tsangpa prince, in a prolonged civil war. His efforts were successful in part because of aid from Güshi Khan, the Oirat leader of the Khoshut Khanate. With Güshi Khan as a largely uninvolved overlord, the 5th Dalai Lama and his intimates established a civil administration which is referred to by historians as the Lhasa state. This Tibetan regime or government is also referred to as the Ganden Phodrang.
[EX A]: Who is known for unifying the Tibetan heartland under the control of Kagyu?

[EX Q]: Passage: Red hair varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at least 1510. Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered. (See red hair).
[EX A]: How does copper hair vary?

[EX Q]: Passage: Digimon was first conceived as a virtual pet toy in the vein of Tamagotchis and, as such, took influence from Tamagotchis' cute and round designs. The small areas of the screens (16 by 16 pixels) meant that character designers had to create monsters whose forms would be easily recognizable. As such, many of the early Digimon—including Tyrannomon, the first one ever created—were based on dinosaurs. Many further designs were created by Kenji Watanabe, who was brought in to help with the "X-Antibody" creatures and art for the Digimon collectible card game. Watanabe was one influenced by American comics, which were beginning to gain popularity in Japan, and as such began to make his characters look stronger and "cool." The character creation process, however, has for most of the franchise's history been collaborative and reliant on conversation and brainstorming.
[EX A]:
What was originally based on an actual pet?
