Which sentence from the article supports the idea that physical and historical evidence played a key role in determining that the Magna Carta at Harvard was an original?

Suspecting that it was an original, the professor and a fellow scholar authenticated the document by comparing it to other originals.
Perhaps more compelling, however, than how or where these works were recovered is the remarkable endurance of the ideas they contain.

The faded document sold for so little because it was believed to be a copy.

Answer 1
