Task: Question Answering
Input (English): Passage: As I was taking a picture of dolphins swimming in the ocean , my camera suddenly ran out of power and turned off . I needed to change the battery . Going to a store near the beach , I bought myself two double A batteries . A opened the compartment door with relative ease . I pushed both batteries in a bit to loosen them and then carefully removed both batteries currently in there . I opened up the pack of double A 's I bought with a pair of scissors . Then , making sure I aligned the batteries appropriately ( with the positive side pointing down on one of them , and pointing up with the other ) , I slid the new batteries into place . With fresh batteries I can continue taking pictures of dolphins . Question: How long did it take for the camera to work? Option1: A few hours. Option2: The length of time to replace the batteries with new.
Output (English): The length of time to replace the batteries with new.
