The headlines below were taken from newspapers following natural disasters. "Volcanic Ash Creates Air-Travel Chaos: Worst Delays Since 9/11"
• "Arizona Fires Force Road Closures Around State"
"Japanese Road Reopened After Destroyed by Quake"
These headlines demonstrate that -
A
natural disasters only affect nearby areas.
B.
lives can be saved by predicting natural disasters.
C.
natural disasters can cause major interruptions in transportation.
D.
railroads are the only mode of transportation immune to natural disasters.

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!
