Passage    Three

Questions 31 to 35 are based on the following passage.

The journey two divers made some time ago to the very deepest point on the earth makes us realize how much of the world still remains to be discovered. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents or signs of life.

It was necessary to set out early, so that the ball would come to the surface in daylight, and be e easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.

The divers felt as if they were going down steps as they passed through warm and cold layers of water. In time, the temperature dropped to freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then at a depth of 3,000 feet, the telephone stopped working and they were cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise: even the smallest hole in the ball would have meant instant death.   Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea-creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled   by the great water-pressure. But they did not dare to leave the lights on for long, as the heat from them would make the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none the worse for their experience.
