Answer:
all of the above
Explanation:
Jobs people choose, what they do in their free time, how they travel, are all the consequences of the Earth's physical activities.
Vegetation, climate, land formation influence peoples' lives as people need to adapt to all the features of Earth and control and constrain the choices people make.
I believe the answer is C. This is because all three headlines include information about transportation systems (first one with air delays, second with road closures and third with roads being reopened) being effected by natural disasters.
Here are why the other ones are incorrect:
A. In headline 2 with Arizona, it states how wildfires caused road closures around the state and not the area of the wildfire (headline 1 also disproves this answer, since it says “Worst delays since 9/11”, meaning it effected a lot more than the nearby area).
B. None of these are predicting natural disasters occurred, as seen by some of the language: “Arizona Fires FORCE road closures” (present tense, not past).
D. These do not mention anything about railroads being immune, so it can’t be it.
Hope this helps!
