A Day with Humpbacks I sit on the headlands of Neah Bay, Washington, and watch a mother humpback and her calf slip through the icy Pacific waters. I recognize this whale by her distinctive tail pattern, as unique to this humpback as my fingerprints are to me. Once, heavy hunting using harpoons extirpated the species from the region, and only a ban on whaling allowed populations of humpbacks to recover. As this gray female rises to the surface, she exhales, sending up a spout nearly 20 feet high. She rolls on her side and lifts her scalloped-edge flipper in salute, then slaps it on the water. Fadjust my lens and take my shot. This is the only type of whale hunting I find acceptable with a camera. Which of the following statements conveys the main idea of the passage?
A. Humpback whales travel in waters near Washington.
B. This particular humpback whale has never been seen previously by the author.
C. Cameras and harpoons are both ways of hunting humpback whales
D. Humpback whale populations are finally recovering after nearly being wiped out.
The main idea of the passage is that humpback whale populations are finally recovering after nearly being wiped out due to heavy hunting using harpoons, and the author is now observing and photographing these recovered humpback whales in Neah Bay, Washington.
Therefore, the Correct Answer is D.
