Authors use tension so that it creates for excitement and is more interesting for the reader/audience. By telling the story backwards or by telling the story in bits and pieces to finally join all the pieces and show you a masterpiece( the whole picture). By heightening the emotions of the characters and the situations. An example of dramatic irony is when the author uses Oedipus not knowing he was the killer and making a promise that he shall kill the person who killed his <span>father. </span>
The narrator starts off by correcting Hillary's account and telling his own version of the story - and then, he supplements the story with a previously unknown detail: who made it first to the top.
Right from the beginning, he says that Hillary's account was not completely true. Hillary had claimed that the narrator ran out of breath many times. However, according to the narrator, both of them were equally hardy, and both of them equally supported each other.
Then, he goes on to explain how the two of them were partners, rather than the one who leads and the one who follows. Neither of them would have made it without the other. Mountaineers know this, he says, but common people only wish to know who it was that first made it to the top. And then, he uncovers this detail: it was Hillary who first stepped there. Thereby, the narrator reinforces his position, as the person who tells the truth, even when it is unfavorable <span>to </span>him.
It is most likely the Climax because if you look at a literal pyramid the climax is the very top. Its pretty much when issues hit and problems become worse and people dont know what to do.
