Explanation:  This is a passage related to the work "Unbroken" by American author Laura Hillenbrand. The writer interrupts Louis's story by inserting information about Japan and Germany, thus better informing readers of the background of the story. The broader picture of Zamperini is acquired in this way, that is, how Zamperini's life can be changed by war. Although Louis Zamperini may have had different plans after participating in the 1936 Olympics in Berlin, his plans were interrupted by the war. Although he had some plans of his own, he never dreamed that he would survive a plane crash in the Pacific Ocean, swim for 47 days on a raft and spend two and a half years in three brutal Japanese camps. The idea is that the world around us changes as often as we don't want it to.
