Final answer:
The Mountains and Basins region would be the best for a lumber industry due to its high mountain ranges, which provide a good source of timber. The practice of potlatch is associated with the Pacific Northwest region. The Eastern Woodlands region is not ideal for a lumber industry.
Step-by-step explanation:
The best region for a lumber industry would be Mountains and Basins because this region has high mountain ranges which provide a good source of timber for the lumber industry. The practice of potlatch is associated with the Pacific Northwest region due to the indigenous cultures that practiced it in that area. The Eastern Woodlands region would not be ideal for a lumber industry because it is wetter and lusher, with a variety of plants and animals, but not necessarily a large supply of timber.
