Especially the first part of the first episode they showed ( two half hour episodes ) . Acetylene torpedoes ! Something went wrong at an acetylene place , and sparked a fire , and all those tanks took off like missiles ! I do n't know why they did n't shut down traffic both ways instead of just one .

Question: In what situation , did they shut down the traffic ?
Answer: In the TV episode where the missile place caught on fire .In the real life where the acetylene place caught on fire .In the real life where the tank place caught on fire .None of the above choices .
