Step-by-step explanation:
In “Through the Tunnel,” when Jerry is swimming through the tunnel, his body gets stuck at a narrow point in the tunnel and he feels a surge of panic. He must overcome his fear and the physical challenge to push through to the other side. Moreover, while navigating through this narrow underwater passage, he mistakenly thinks he is at the end when he sees sunlight through a crack, which gives him a fleeting moment of false hope before he realizes he still has a distance to swim to reach the open sea.
