The correct answer is D-the best jewel in the world.
Explanation: Columbus realized that the members of his crew were not as open, honest, caring and loving as the Native Americans who greeted him when he arrived on their shores. Since the Native Americans had never seen people like this they found them to be god-like, thus shiny broken glass, which they had never seen, given to them as "treasure," would be considered a great gift. Thus, Columbus would not allow his men to trade broken crockery or glass for more valuable items.
