Question

read the excerpt from the riddle of the rosetta stone by james cross giblin.
the middle hieroglyph was unknown to him, but he guessed that the two at the left symbolized the sun.
from his studies of coptic, champollion knew that the egyptian word for \sun\ was pronounced rah. he wrote down the first two letters of that sound, ra. next he put a question mark for the unknown middle hieroglyph. then, at the end, he wrote ss, the sound of the last two hieroglyphs.
he studied the combination: ra? ss. suddenly he remembered a famous pharaoh whose name appeared in ancient greek chronicles, and also in the biblical book of exodus: rameses, or ramesses. could this be a hieroglyphic representation of ramesses name?
the details in the excerpt point to which big - picture idea?
hieroglyphs are both a representation of sounds and symbols.
several famous names can be found in the biblical book of exodus.
the sun has symbolic meaning in many different cultures.
champollion knew that the egyptian word for \sun\ was pronounced rah.

Explanation:

The text shows that Champollion analyzed hieroglyphs. He associated the left - two hieroglyphs (symbolizing the sun) with the sound "rah" (RA), used a question mark for the unknown middle one, and took the sound of the last two as SS. Then he related this combination (RA?SS) to the name Rameses. This indicates that hieroglyphs can represent both sounds (like RA and SS) and symbols (the sun symbol). The other options are either too narrow (only about names in a specific book or the sun's meaning in different cultures) or just a fact (Champollion knowing the Egyptian word for "sun" pronunciation) rather than a big - picture idea.

Answer:

Hieroglyphs are both a representation of sounds and symbols.
