Read the following sentences. "Some experts think that overfishing is one of the main reasons the population of the Nomura's jellyfish has been increasing. The Nomura's jellyfish eats the same types of plankton as many fish do in the Sea of Japan. Usually, because the jellyfish and fish are competing for food, the two groups stay about the same size. But due to overfishing in the Sea of Japan, there are less fish in the water than there were in the past. This means that the Nomura's jellyfish has a larger food supply. Because of this larger food supply, the Nomura's jellyfish population has increased more and more."

• A. The fish in the water have decreased from poor weather and so the Nomura's jellyfish food supply has increased.

• B. If the Nomura's jellyfish did not eat plankton, their population in the Sea of Japan may not have declined.

• C. The fisherman drop fish bait in the Sea of Japan which gives the Nomura's jellyfish more food to eat.

• D. If humans had not fished in the Sea of Japan, the Nomura's jellyfish population may not have increased.
