Answer:
Some heard that gold and silver could be found in Louisiana.
Step-by-step explanation:
Jon Moen's "John Law and the Mississippi Bubble" is an article that deals with the historical events of when John Law consolidated the trading companies in Louisiana and made it into a monopoly resulting in what is now known as the Mississippi Bubble. This event in history ended in a financial disaster for all involved.
According to the given excerpt, the writer mentioned how the French did not have any idea about where America was but have "heard the rumor that this land was rich in silver and gold" which captured their attention. This rumor led the French to reconsider the value of the American colony of Louisiana.
Thus, the correct answer is the first option.
