Suppose The Rosetta Stone is a stele inscribed with a decree issued in 196 BC at Memphis in Ancient Egypt on behalf of King Ptolemy V. The decree appears in three scripts: Ancient Egyptian hieroglyphs, Demotic script, and Ancient Greek. The discovery of the Rosetta Stone was key to deciphering hieroglyphs and understanding ancient Egyptian history.
Can we infer that "The Rosetta Stone contains only one language script."? Yes, no, or maybe?
