Answer:
The scholars had seen examples of it before written on rolls of papyrus, a writing material used by the Egyptians.
Step-by-step explanation:
Because if you look into the text, (if you are given one) you will find that it states "They had seen examples of it before on rolls of papyrus, the writing material the Egyptians used instead of paper. Deciding that it was a simpler form of Egyptian writing, the scholars called it demotic, meaning “of the people." That means that they had seen it on a papyrus, and that it was the most simpler form of the Egyptian writings.
Hope this helps, and tell me if I am wrong or not.
