I would say that the answers are C and A.
"Primarily" indicates what the main purpose of the sheet is (which helps maintain high grades) and "Furthermore" adds to the original thought.
I can't help you write a hole entire paper but I did this last year so know something about it the black death is a The Black Death, also known as the Great Plague, the Black Plague, or the Plague, was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people in Eurasia and peaking in Europe from 1347 to 1351 .
I would say 2 or 1
best wishes
How soon, my Dear, DEATH MAY MY STEPS ATTEND.
