For me, the answer is letter D.
Only choice D has the technical words associated to geography. The rest of the choices contain common words that any mundane could use. But choice D talks about geology itself in the ocean which is highly influenced by drilling and mining. Knowledgeable readers would understand this because drilling and mining require workers to tap into the geological rocks deep beneath the ground which may cause a significant alteration in the oceanic geology.
The reason writers should take a break between writing the first draft and the revising stage is so to have a fresh perspective on what they have written<span>. Too often after writing a first draft, writers feel a strong connection to their work and are not welcome enough to begin the critiquing process. They are still in the same mindset of what they just created and do not want to change it or cannot see it from a different perspective that may benefit the work. Thus, they should take a break and come back to it later when they are refreshed and able to critique their work in order to revise it. </span>
