Question

At the end of the fourth paragraph ("And below the surface... scour marks"), the author strategically arranges sentences in a way that

Answer 1

Answer: E. Emphasizes the mounting evidence for the complexity of the ocean’s currents

Explanation:

The author begins these sentences with “And below” to claim that beneath the surface currents there are other distinct currents with different speeds, directions, and volumes. By repeating “And below” at the beginning of the next sentence, the author suggests that there are yet other currents beneath these. The author’s arrangement of these sentences therefore suggests that the layers of distinct ocean currents are potentially endless. After making this suggestion, the author then includes the fact that there is photographic evidence supporting the idea that there are currents on the sea bottom, which had once been thought to be still. By arranging the sentences in this manner, the author affirms her claim regarding the unending complexity of the ocean’s current by revealing that there is already proof to support the claim.
