Based on The Riddle of the Rosetta Stone, how do the findings of Jean-François Champollion differ from the findings of Thomas Young?

C. Unlike Young, Champollion traveled to Egypt, which allowed him to study other hieroglyphic inscriptions and decipher the hieroglyphs on the Rosetta Stone.

Explanation:

The question above is related to the book entitled "The Riddle of Rosetta Stone," written by James Giblin. The book is all about deciphering the Egyptian history regarding "hieroglyphics."

In contrast to Thomas Young, Champollion differ in findings because of his opportunity to travel to Egypt and study many hieroglyphic texts.

He was also excellent in deciphering even at a young age. This made him a member of many scientific circles and an advanced position of speaking both Arabic and Coptic fluently. In deciphering the Rosetta Stone, he was able to show that the Egyptian system of writing consisted of both the ideographic and phonetic signs.

So, this explains the answer.
