I didn't know any of it, so I only got 4/10. I tried to guess what a Christian would say, but mostly I just guessed.
1.
Figured Mormons are named after Moroni.
2.
Lucy guess.
3.
Guessed a gold copy of the Bible. Didn't think it would be the Urim and Thumim, being as Smith lived in the US and the Urim and Thumim was a breastplate. Figured it was just a silly answer like the GPS one.
4.
Guessed that he brought them home to translate. Didn't have a clue.
5.
Guessed they ignored him. I guess there's nothing like persecution to make a Christian feel vindicated.
6.
Guessed that things probably wouldn't have progressed very far if the other translator wasn't buying it.
7.
Not a clue.
8.
Guessed he used a dictionary. Not sure how the Urim and Thumim would be functional as a dictionary, nor how they ended up in the US.
9.
Guessed Utah since I think that's where all the Mormons live.
10.
Figured there had to be a "reason" why these plates were no longer available for analysis.
