Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the
Ratling [72]

Read the excerpt from The Riddle of the Rosetta Stone, by James Cross Giblin.

Another, more complete copy of the same decree that appeared on the Stone was found on a slab at Philae in 1848. Fuller translations of the hieroglyphic text soon followed. A Latin version came out in 1851, a French one in 1867, and an English one in 1871. But many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone.

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone?

Answer:

many of the hieroglyphs on this slab were missing

Explanation:

The detail from the excerpt that develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone is "many of the hieroglyphs on this slab were missing."

From the available excerpt, it was written that despite many translations of the original text, including the fuller version, the French translation, the Latin version, and the English version, "many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone."

lianna [129]
<span>If a population is not in Hardy-Weinberg equilibrium that can cause deviations from expectation depending on the assumptions of HW that are violated. If a population violates some of the assumptions (like mutations, migrations and selection) the allele frequencies will change over time. Also, if a non-random mating occurs (like inbreeding), it will cause an increase in homozygosity for all genes.</span>
