Answer:
3) b. A globe
4) e. Human-environment interaction
Step-by-step explanation:
For 3):
A globe is the most realistic way to view the earth. It is the most proportional and, therefore, it is the most accurate view of the entire earth.
For 4):
If you see humans interacting with the environment in ANY way (cutting trees, farming, building dams, etc), then it is human-environment interaction.
