This question is incomplete, here´s the complete question.  

Blue Whales

Joshua Tigue

1. Blue whales are the largest animals on Earth. They can measure up to 110 feet long and weigh as much as 400,000 pounds. Blue whale babies are born big. They can weigh as much as 6,000 pounds at birth. They grow for one full year to reach their adult size.

2. Blue whales live in the ocean. They swim fast, which helps them catch food. Blue whales must eat up to 8,000 pounds of food each day. They eat tiny fish called krill. To eat, the whale opens its mouth and lets the krill swim in. Once the krill are inside, the whale begins to close its mouth. It does not close the mouth the whole way, though. The whale shows its baleen. Baleen are long, strong hairs that act like teeth. The baleen allow the water to flow out. The baleen keep the krill in. The whale can then eat the fish.

3. Blue whales are named for their color. However, they are not really blue. Although they look blue under the water, they are actually gray. Blue whales prefer to swim alone. Their bellies are yellow.

4. Since blue whales are mammals, they must breathe air. Blue whales have a blowhole on the tops of their heads. A blowhole is like the nostril in a human nose. It lets blue whales breathe the air in and blow it back out. When whales go underwater, they can close their blowholes. They can open their blowholes when they want, too.

5. Because of their size, blue whales cannot be harmed by many other animals. This means they can live safely for a long time. They can live eighty or ninety years. Some even live to be one hundred years old!

B) the importance of size and the fighting habits of blue whales

C) the strange eating habits of large and small ocean mammals and krill

D) the various ways blue mammals protect themselves and eat krill

Answer: A) the importance of size and interesting eating habits of blue whales

Explanation:

The fact that blue whales are big (they can be up to 110 feet long) is important because its the reason they can´t be hurt by other creatures. And despite their size, they can swim very fast, as a means to catch the 8,000 pounds of krill they need to eat every day.

Sunny_sXe [5.5K]

The correct answer to this open question is the following.

There is no question here. It is just a statement.

Furthermore, you did not specify if this statement belongs to a novel, a play, a movie, or what?

It is so difficult to help you without the question and the proper references.

However, trying to help you, we can infer that you are talking about the ghost in the play "Hamlet," written by English author William Shakespeare.

Being that the case, yes, the appearance of the ghost helps create an eerie mood and grabs the audience's attention. Shakespeare, being the expert writer he was, knew how to create suspense in the readers. As the ghost does not speak, this adds mystery and suspense to people's minds. The audience would probably want to know more about the ghost in the king's clothes and ist purpose to appear. Most people could think that the ghost is there because it has issues to resolve.
