Read the excerpt from The Riddle of the Rosetta Stone.
The French army stayed behind in Egypt—and so did the scholars. In late August, shortly after Napoleon's departure, a large, heavy package arrived at the scholars' palace in Cairo. When they opened it, they found it contained a black stone slab covered with writing in three different scripts.
A note from a French army officer accompanied the package. He told the scholars that the stone had been unearthed in an old fort near the town of Rosetta, thirty-five miles north of Alexandria. French soldiers were tearing down a ruined wall in the fort when they came upon the slab.

the translation of the last sentence of the Greek text
Explanation:
According to the sequence of events described in The Riddle of the Rosetta Stone, the scholars are led to believe that the three inscriptions say the same thing in different languages because of the translation of the last sentence in Greek which confirmed to them that the inscriptions mean the same thing.
