Delta Kappa Epsilon (DKE) International Practice Test

George H.W. Bush is notably associated with Delta Kappa Epsilon (DKE) due to his membership in the fraternity while he was a student at Yale University. His involvement with DKE is significant as he later became the 41st President of the United States and is one of the most distinguished alumni of the fraternity. DKE has a rich history and a number of influential members, but Bush stands out due to his prominent political career and the leadership roles he has held, which often highlight the social connections and networks formed during his time in the fraternity.

The other figures listed, while significant in American history, do not have a documented association with DKE, making Bush the best choice regarding fraternity affiliation.
