 Why did the narrator initially become frustrated with the task that Captain Walsh gave him.
Perhaps there was method in Colonel Walsh's madness—murder-madness—when he ordered Major Polk to scan the planet for a guy named Joe. For example, he could have chosen a Second Looie for the job on Venus. The rest was gravy, and Colonel Walsh wasn't going to let me get by with gravy. "It will be a simple assignment, Major," he said to me, peering over his fingers. If Walsh really wanted to know the reasons for the revolt, I could give them to him in one word: Walsh. It had been going on for six months now and we'd lost at least a thousand men from Space II. He'd goofed off on a pile of uranium that could've, and almost did, blow the barracks sky-high that night. And I thought about Colonel Leonard Walsh and how he was supposed to be quelling that revolt. Ever since Walsh had taken command, ever since he'd started pushing the natives around, there'd been trouble. His features, his muscles, everything seemed to have been stretched like a rubber band. "You've got the wrong number," he said, and I was a little surprised at his use of Terran idiom. My orders said I was to report to Captain Bransten immediately upon arrival. I began to curse Walsh for taking me away from my nice soft job in Space II. Walsh was about the lowest, most contemptible.... "Yes," I said, still thinking of Colonel Walsh.
 The task proved much harder than the narrator thought.
 The narrator realized the directions he was given were unclear.  The task proved much harder than the narrator thought.  He realized that he was part of a more important mission.  He realized he was sent to the wrong planet.
