Task: Question Answering
Input (English): Passage: I wanted to take some pictures with my camera , but when I turned it on , nothing happened . I realized the batteries were old and needed to be changed . The first thing I did was open the battery cover on the camera to take the old batteries out and double check to see what size and how many batteries I needed .  I went to my storage drawer where I keep batteries and got two new AA batteries for the camera . I put the batteries in the camera the proper way , which was shown on the inside of the battery area . I replaced the cover of the battery area and snapped it into place to secure the batteries in the camera so they would n't fall out when I used it .  It came on , and I was ready to take pictures . I then properly disposed of the old batteries . Question: When did they find out they needed two AA sized batteries? Option1: When they opened the battery cover on the camera. Option2: before getting camera out
Output (English): When they opened the battery cover on the camera.
