What is the deepest spot in the ocean, and who were the first explorers to reach it?
” We initially tried a Boolean search, using the words “deep” and “ocean”. The most promising sounding result, “deep sea exploration” failed to provide an answer. We then tried a simple search for the word “deep” which, in addition to being an adjective, can also be used as a noun meaning “any ocean area more than 18,000 feet deep”. A brief article on “deep” provided the information we sought. We were then able to find out who was the first to reach the spot, by searching for an article about that deepest spot — the Mariana Trench.
