Task: Question Answering
Input (English): Passage: I am a teacher and I needed to present a PowerPoint to my students . Before class , I got the technical cart with the audio/visual equipment on board and rolled it into my classroom . I turned on the projector to make sure the light was working and I placed the projector where it would shine on my while board . I also plugged in the audio cable . I opened the PowerPoint and clicked play to check if everything worked . First , I turned the focus knob so my PowerPoint came into focus . It looked too small , so I moved the cart farther away from the white board and refocused the projector until I was satisfied with the image . They were turned off , so I turned them on and adjusted the volume . I played the PowerPoint all the way through to make sure it worked . It did , and and my students saw the presentation . Question: What did they plug into the laptop? Option1: audio cables Option2: charger
Output (English): audio cables
