The question is asking us who the two brothers sent to Moravia to help the people were. Moravia is in today's Czech Republic. The question is refering to the two saints in the Christian Faith - known as Cyril and Methodius. So we know that Methodius is the correct answer, but what about Ciril? Ciril was born as Constantine- he changed his name later in life. So they're Constantine and Methodius (the Cyrilic script is named after Cyril)
