Anything else about it , I have n't heard yet . No idea how it happened , especially if the house was actually vacant like my cousin said . My brother was home , and he said the whole house shook and stuff fell off of his bedroom shelf . And we 're on the other side of town from all of this , so it must ' ve been pretty huge .

Question: Why are they talking about things falling off a shelf ?
Answer: None of the above choices .They think an earthquake happened .The whole house shook but was fine .They airplane exploded and fell apart on the house .
