In this task, you're given a context passage, followed by a question that needs to be answered. Based on the paragraph, you must write unambiguous answers to the questions and your answer must refer to a specific phrase from the paragraph. If multiple answers seem to exist, write the answer that is the most plausible.

In 1814 Young first exchanged correspondence about the stone with Jean-François Champollion, a teacher at Grenoble who had produced a scholarly work on ancient Egypt. Champollion saw copies of the brief hieroglyphic and Greek inscriptions of the Philae obelisk in 1822, on which William John Bankes had tentatively noted the names "Ptolemaios" and "Kleopatra" in both languages. From this, Champollion identified the phonetic characters k l e o p a t r a (in today's transliteration q l i҆ w p ꜣ d r ꜣ.t). On the basis of this and the foreign names on the Rosetta Stone, he quickly constructed an alphabet of phonetic hieroglyphic characters, which appears in his famous 1822 "Lettre à M. Dacier" sent to Bon-Joseph Dacier, secretary of the Paris Académie des Inscriptions et Belles-Lettres and immediately published by the Académie. In the postscript Champollion notes that similar phonetic characters seemed to occur in both Greek and Egyptian names, a hypothesis confirmed in 1823, when he identified the names of pharaohs Ramesses and Thutmose written in cartouches at Abu Simbel. These far older hieroglyphic inscriptions had been copied by Bankes and sent to Champollion by Jean-Nicolas Huyot. From this point, the stories of the Rosetta Stone and the decipherment of Egyptian hieroglyphs diverge, as Champollion drew on many other texts to develop an Ancient Egyptian grammar and a hieroglyphic dictionary which were published after his death in 1832.
