The following text is from a poem about the tides. The waters rise and wash the sand, A rhythm old as time— The ocean grips the shifting land, Repeating distinct rhyme— But when the moon begins to wane, Completing its design, The tides will pull away again, Receding in a line— When this high tide has found its end And low tide has arrived.....
Which choice best states the main purpose of the text?
To illustrate the cyclical nature of the ocean tides
To warn people about the dangers of swimming at high tide
To explain the scientific gravitational pull of the moon
To describe a specific storm that destroyed the coast
Correct Answer: A
Choice A is the best answer. The poem describes the waters rising, the "rhythm," the moon waning, and the tides pulling away. It describes the cycle of high and low tide.
Choice B is incorrect. No warning of danger. Choice C is incorrect. It mentions the moon but describes the cycle, not the physics/gravity in a scientific manner. Choice D is incorrect. It describes a regular tide, not a storm.
