"The ocean is not only vast but deep." Here "vast" means

Question 39

EasyOriginal question

Seen from space, the Earth is mostly blue, and for good reason. The ocean covers about seventy per cent of the planet's surface, and it holds about ninety-seven per cent of all the Earth's water.

Most of the rest is locked away. About two per cent of the Earth's water is frozen in and ice caps. Less than one per cent is the fresh water that people, animals and crops depend on, and a tiny floats in the air as water .

The ocean is not only but deep. Its average depth is about 3,682 metres, more than three and a half kilometres. Throughout those depths there is life. In fact, the ocean is the largest space on the planet where living things can survive, and there is more life there than anywhere else on Earth.

Yet we know surprisingly little about it. Most of the ocean has never been , and before scientists can explore a place properly, they must first map it. So the planet's largest home for life is still, in large part, a place nobody has seen.

CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. The passage has just said the ocean covers about seventy per cent of the Earth's surface.

  2. "Vast" means extremely large, and "not only… but deep" adds a second idea to size.

Worth noting

The sentence joins two ideas, size and depth, so "vast" must be about size.
