Let's evaluate each statement:
1. **"Those living in the Northwest had to farm for all of their food."** - **False.** While some farming occurred, many Northwest tribes primarily relied on fishing, hunting, and gathering.
2. **"Those living in the Northwest lived along the rainy coast of the Pacific Ocean."** - **True.** Many Northwest tribes resided along the coast, benefiting from the abundant natural resources.
3. **"Those living in the Southwest lived in moist, rainy climates."** - **False.** The Southwest is generally arid and has a dry climate, not characterized by consistent moisture and rain.
4. **"Those living in the Southwest hunted and gathered."** - **True.** While agriculture (such as maize farming) was significant, many Southwestern tribes also supplemented their diet through hunting and gathering.
So, to summarize: The first and third statements are false, while the second and fourth are true.
