Slavery and the start up of the government
Answer:
Christopher Michael Langan
Explanation:
Christopher Michael Langan (born March 25, 1952) is an American horse rancher and autodidact who has been reported to score very highly on IQ tests. Langan's IQ was estimated on ABC's 20/20 to be between 195 and 210, and in 1999 he was described by some journalists as "the smartest man in America" or "in the world".
All I would know on this matter, is : America joined WWI because of the American lives being lost on Passenger liners such as the RMS Lusitania.
