Task: Question Answering
Input (English): Passage: Private Meredith Bixby simply cannot fall in line with army procedure, even though he has had 17 months of training. A psychologist, is assigned to turn him into a good soldier, so she enlists two fellow servicemen to help Bixby with his training. About the only thing that he can do right is remember things with his photographic memory.
Eventually they are assigned to a base in Morocco. One night they all head off to a bar where Bixby gets drunk on "Moroccan Delights", which he thinks are malteds. He gets involved with a femme fatale and is kidnapped by some Arabian renegades.
Abdul guards Bixby and makes him assemble a stolen cannon, knowing that Bixby had already memorized the assembly instructions back at the base. Bixby is eventually rescued by his fellow soldiers and they are all presented with medals of honor. Unfortunately, when Bixby mishandles a rifle that suddenly goes off, he damages the drinking glasses of the General and two visiting French officers. The trio (who are drinking a toast) are not hurt, but misfit Bixby gets punished with KP duty, peeling potatoes. 
Question: What does the Private fumble with to end up peeling potatoes?
Output (English): a rifle.
