Answer:
C. Multiple languages were carved on the Rosetta Stone.
Step-by-step explanation:
Using process of elimination we get to the answer c. A is not right because the passage says nothing about what languages Alexander the great spoke, only that he passed away. B is not right because the passage doesn't say anything about the Romans replacing the languages with Latin, only that the Romans conquered Egypt in 30 bc. The Ptolemy family and the carving of the Rosetta stone happened before then, and since this passage is focusing on the Ptolemy family and Rosetta Stone, whatever the Romans did after conquering doesn't matter. Finally D is not right because the passage says nothing about the priest only understanding Greek. The the statement of the priest was written by people who knew Greek and Egyptian, not the priest themselves.
