Take the following as truth: In the dohyo, a raised mound of hard clay some 4.6 m (15 ft) in diameter under a large suspended Shinto-roof-style canopy,toss salt across the dohyo to purify it of evil spirits, swagger around, and commence the all-important  psyching-out  of the opponent.
Then the following statement: "Evil spirits are encouraged to take up residence in dohyos." is true, false, or inconclusive?
Answer: False
