Final answer:
The question about AKPsi's membership policy changes in 1950 cannot be verified with the provided information; hence, a definitive answer cannot be given. The information available discusses societal attitudes about race and religion rather than the specific history of AKPsi.
Step-by-step explanation:
The student asked if the statement that membership into AKPsi (Alpha Kappa Psi) was originally restricted to men who were of Christian faith and Caucasian race, but this clause was removed after a chapter congress vote in 1950 is true or false. The provided information does not include specific details about AKPsi's historical membership policies, instead focusing on the cultural and social dynamics of the Ku Klux Klan and discrimination against Jewish Americans and other minority groups in the United States during the 20th century. Without specific references to AKPsi's history, we cannot verify the statement's accuracy, thus we should refuse to answer. However, the question itself deals with the transformation of societal attitudes toward race and religion as reflected in the membership policies of fraternal organizations, suggesting broader shifts in American culture during that period.
