True. There were many colonies that had policies that allowed newcomers to get land for free. The only thing they had to do is work on it and grow crops and have farms, and after a while the land would completely become theirs and they wouldn't have to work on it anymore if they didn't want to.
The correct answer is iron and wood. This opened up a lot of job opportunities for people who managed to deliver that and it made many people in that industry wealthy. This enabled the rise of big time capitalist company owners that did whatever they wanted.
