Same thing from the other question I answered.
I believe the answer is: A. The church combined both Greek and Roman architecture, and became a melting pot where Eastern and Western cultures came together.
The combination became a proof of Cultural Assimilation that occurs between eastern and western church due to the good relation that exist between them. This indicate that in the past people from Byzantine and Roman empire were free to visit each other's region either for business, tourism , or studying.
The answer fam is........ "They bribed their rivals with land." "They married royalty from other powerful lands." And "They challenged their rivals in Olympic competitions." The other options are tactics they did use.
