Problem: In 2010, 6.9% of the population (1,269,765) considered themselves to be of only American ancestry (regardless of race or ethnicity). Many of these were of English or Scotch-Irish descent; however, their families have lived in the state for so long, that they choose to identify as having "American" ancestry or do not know their ancestry. In the 1980 United States census the largest ancestry group reported in Florida was English with 2,232,514 Floridians claiming that they were of English or mostly English American ancestry. Some of their ancestry went back to the original thirteen colonies.

Problem: The earliest Tibetan historical texts identify the Zhang Zhung culture as a people who migrated from the Amdo region into what is now the region of Guge in western Tibet. Zhang Zhung is considered to be the original home of the Bön religion. By the 1st century BCE, a neighboring kingdom arose in the Yarlung valley, and the Yarlung king, Drigum Tsenpo, attempted to remove the influence of the Zhang Zhung by expelling the Zhang's Bön priests from Yarlung. He was assassinated and Zhang Zhung continued its dominance of the region until it was annexed by Songtsen Gampo in the 7th century. Prior to Songtsän Gampo, the kings of Tibet were more mythological than factual, and there is insufficient evidence of their existence.
Who annexed the Zhuang Zhung in the 1st century BCE?
