Read the passage carefully, then choose the best answer for each question.
THE LOST CITY OF ATLANTIS
Most people have heard the story of the lost island of Atlantis. But is any part of the story true?
Over two thousand years ago, the Greek writer Plato wrote about Atlantis, an island in the Atlantic Ocean. The island's people were very rich. They built a big city with many great buildings. At the center of the island, they built a beautiful golden temple.  But the people became greedy—they had many things, but they still wanted more. So the gods became angry, and the island was struck by earthquakes  and very large waves. Finally, the whole island sank into the sea.
Many explorers have looked for Atlantis. In 2004, explorer Robert Sarmast reported finding the remains  of a city under the sea near Cyprus. However, Sarmast and other scientists later found out the structures he found under the sea were natural, not man-made.
Many people think Atlantis is simply a story. The purpose of the story is to teach people not to be greedy. Richard Ellis wrote a book about Atlantis in 1999. He says "there is not a piece of solid evidence''  for a real Atlantis.
So was the island real or not? We only know one thing: The mystery of Atlantis will be with us for a long time.

A.Scientists found out the structures were natural.
B.Explorers found a city under the sea near Cyprus.
C.People are looking for Atlantis, but no one has found it.
