Did pocahontas teach john rolfe how to cure cotton, which made it a profitable crop for the colonists?

This sentence is False.

This is false for the simple reason that it was not cotton Rolfe found out how to cure but tobacco. It was indeed tobacco that made Jamestown a successful colony not cotton. The other thing is that Pocahontas did not teach him that but he found it out by conducting experiments. He was married to Pocahontas though.
