Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms. The warm air rises through the colder air, causing an updraft. The updraft will begin to rotate if winds vary sharply in speed or direction1

Answer:
A
Explanation:
Because South America is covered in two sides, the long coast line in chile, and the other side with brazil
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!
