Answer:
Step-by-step explanation:
This is tough and requires a level of interpretation. I will refer to the modifications in the box as 1-3 in the order they are listed and the possible answers I will refer as a-d in the order they are listed. Lets analyze:
First the question; it's asking us, based on 1-3, which one of a-d are the most true to answer the question, "why did the colonist modify the environment?"
I will start with what is most false and work to find our answer. B is not the answer. Nothing in 1, 2, or 3 applies specifically to protection.
C is not the best choice. While 1 and 3 could apply, 2 simply does not.
D is a tough one. It could be argued that the impact of all 3 answers are to encourage development of the trade we with England, but that is relying on outside information not provided to us. The statements 1, 2 and 3 have no specific mention of britain or trading.
That leaves A. 1 says clearing forests for lumber. Lumber is an economic good. 2 is also a economic good. 3 applies to transportation of goods as well as the town's that are needed for people to live and trade goods and services.
I believe answer A is the best choice.
