According to Oriad, Which of the Following Are True

According to Oriad, which of the following are true?

A) Referees were needed in American sports because Americans had a different attitude towards sporting competition than did the British who invented soccer and rugby.
B) British amateur athletes operated under a "code of honor" that was associated with the elitist class - the aristocracy, that provided the major source of "amateur" athletes in Great Britain. Captains, not referees, enforced the code which was used to support the social status and expected behaviors of the British aristocracy.
C) Americans, in contrast, had no such "code of honor", did not have a ruling aristocracy and primarily thought of themselves of the "middle class" which had no "code of honor" so there was no "code of honor" to break.
D) As a consequence of no "code of honor" to adhere too, Americans sought to exploit the rules of athletic competitions as much as they wished to enforce the rules.
E) All of the above.
