Read the sentence below. Replace the underlined word with a synonym (a word that means the same thing).
In 1953, Sir Edmund Hillary and Tenzing Norgay became the first people to reach the summit of Mount Everest on the Nepal-Tibet border.
As you have not identified a word for me, I am going to guess that the word in question is 'summit.' If so, then words such as 'top' or 'peak' would be appropriate substitutions.
