Model answer: To count the missing annotations, I need to identify how many cans are in the image and how many have annotation boxes. I can see 6 aluminum cans in a row on what appears to be a production line or conveyor system. Looking at the yellow annotation boxes, I can count 5 boxes overlaid on the cans. Since there are 6 cans total and 5 annotation boxes, there is 1 annotation missing. 1
