Read the text about Titanic and number the paragraphs in the correct order.

a) However, by the following morning it was clear than more than 1,500 people had died and that only about 700 passengers had survived.

b) It was making good progress across the Atlantic when, on the night of Sunday 14th April, the five days after setting out, it hit an iceberg. A telegram was sent saying: “We have struck an iceberg.”

c) On Tuesday 16th April, the headlines in the newspapers read: “Titanic sunk, no lives lost” and “All Titanic passengers are safe.”

d) The ship went down within three hours of hitting the iceberg. It sank nearly four kilometers, to the bottom of the ocean. Some passengers managed to escape but there weren't enough lifeboats to save everyone.

e) Titanic was the biggest, fastest and most luxurious liner of its time. In April 1912, the ship set sail on its maiden voyage from Southampton in Great Britain to New York.

f) While the passengers in the lifeboats were desperately trying to survive the freezing temperatures, the nearest ship, the Carpathia, had answered Titanic's call for help and was heading at full speed to rescue them. It took the Carpathia four hours to reach the place where the ship had sunk.
