Apparently ( keep in mind , I ' m not good with the car talk ) , a rod blew , creating a spark in the engine which set the oil on fire . We grabbed all our stuff out of the car in case it blew up , and called the fire dept . We also called Aaron and Amy to turn around and come rescue us .

Question: Why did they call the fire dept ?
Answer: Because they grabbed all their stuff out of the car .Because they thought a fire might erupt .Because a rod blew .None of the above choices .
