Answer:
The Authors purpose in writing this article, “The Aqua Lung: Bringing Ocean Exploration to New Depths,” is to tell. It is an informative article. Like the title indicates, the aqua lung did bring undersea exploration to new depths (that is a pun, by the manner), by using manner of making exploration to be had to “ordinary people.” The way you can decide what the reason is in an editorial is with the aid of searching at the start first couple of paragraphs as well as the ending paragraph. The beginning, as you recognize, may have the thesis (or subject matter), and this is where you’ll get the clues with reference to what the factor of the writing is.
As you can probable also know, the finishing (or end) is wherein the thesis/subject matter will be reiterated. As such, you’ll be seeking out what's stated two times—at the start and at the stop. In the beginning, it is noted that the Aqua Lung “made it viable for greater people to discover the ocean’s depths.” And, in the ending it states that “Cousteau’s greatest legacy as a conservationist may have been giving ordinary people the tools needed to view the wonders of the ocean firsthand.”
