Final answer:
The early settlers were attracted to the Northwest by the plentiful resources of timber and fur, which were the primary commodities they sought in this region. So, the correct answer is option a.
Step-by-step explanation:
The two early resources that attracted settlers to the Northwest were timber and fur. This region, known for its dense forests, offered ample timber for those looking to engage in logging, while the abundance of wildlife provided lucrative opportunities in the fur trade.
Unlike other regions where gold, silver, and cattle ranching were major draws, the Northwest's dense forests and the richness in animal species made timber and fur the primary initial resources that settlers sought after.
