1 when you imagine the ocean floor, perhaps your mind swims with huge, mysterious creatures full of sharp teeth and scaly skin. exotic animals like the giant spider crab, fangtooth fish, and giant tube worm make their homes at the bottom of earth’s oceans. however, at even deeper depths, between 9,800 and 13,000 feet (3,000–4,000 meters), there lives a creature so small, round, and adorable that scientists, upon spotting the elusive beast, are likely to say nothing more than “aww!” (paragraph 1)

which central idea does this paragraph support?
○ the dumbo octopus has similar features to giant tube worms.
○ the dumbo octopus is unlike other creatures living in the deep sea.
○ the dumbo octopus is more common than other forms of sea life.
○ the dumbo octopus has adapted to harsh conditions on the ocean floor.

Explanation:

The paragraph first describes other deep - sea creatures as having sharp teeth, scaly skin, etc., and then introduces the Dumbo octopus as small, round, and adorable, different from those creatures. Option A is wrong as there's no info on similar features to giant tube worms. Option B is wrong as the text shows it's less common in appearance. Option D is wrong as the text doesn't talk about its adaptation. Option C correctly states that the Dumbo octopus is unlike other deep - sea creatures.

Answer:

C. The Dumbo octopus is unlike other creatures living in the deep sea.
