Concept:This is a sentence rearrangement task that tests logical narrative flow, particularly cause and effect in a description of a ship's voyage.
Explanation:The opening phrase "As the ship streams from San Diego" sets the context of departure.
Part S logically follows: "those of us aboard have a personal demonstration of powerful ocean movement."
Part P then explains the source of that movement: "as walls of gray water from a distant storm in the North Pacific."
Part R describes the immediate effect: "rock and toss the ship."
Part Q gives the final consequence: "making the greener among us miserable with seasickness."
Thus the correct sequence is S followed by P, then R, then Q.
Answer:The correct sequence is option C: S P R Q.
