Task: Question Answering
Input (English): Passage: I was sight seeing and wanted to take some pictures , so I brought my camera with me . At the first sight I got my camera out of the case , took off the lens cap , turned it on , and looked through the viewfinder . Before I could even focus on the scenery , I noticed the red " low battery " light blinking on the screen . I turned the camera back off , and dug around in the camera bag to find a new battery which had a full charge . I was careful to look at the direction in which I took it out , because sometimes I forget the right way to insert the new battery , even though there is a diagram on the inside of the compartment . I placed the old battery back in my camera bag , and then I inserted the new battery into the compartment . I clicked the cover back in place and turned the camera back on . When I looked through the viewfinder this time , I had a full battery and was ready to take all the pictures I could want ! Question: What did the person open? Option1: The battery compartment on the camera. Option2: The camera's battery.
Output (English): The battery compartment on the camera.
