Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions from 39 to 43.

Can you imagine waking up each day in a house that is gently rocked by the movement of water, having a water park as a garden and getting to work by water taxi? Well, for some people this vision of the future may become a reality. It is a commonly accepted fact that as the Earth’s temperature rises, the ice caps at the North and South Poles will melt, causing the sea level to rise.

So, where does this leave the many countries in the world which have large sections of their populations living in areas which lie at or below sea level? The Netherlands, for example, is one of the most highly populated, low-lying countries in the world and has been battling with the problem of flooding for years. Further rises in the sea level would mean much of the country will disappear under water.

Inventive architects may have come up with a solution to the problem: a floating house actually built on the water. The basic idea is that houses will have a base filled with air and a way of anchoring them to the ground. This will allow the houses to float upwards whenever the sea level rises and sink back down when the sea level drops. So, are floating houses the homes of the future? For some people there may be no alternative; for others it will be through choice. After all, who says you have to live on dry land anyway?

Which of the following statements best expresses the main idea of the passage?

According to the passage, which of the following is NOT true?

The word “ceased” in paragraph 2 mostly means _______.

If you go back far enough, everything lived in the sea. At various points in evolutionary history, enterprising individuals within many different animal groups moved out onto the land, sometimes even to the most parched deserts, taking their own private seawater with them in blood and cellular fluids. In addition to the reptiles, birds, mammals and insects which we see all around us, other groups that have succeeded out of water include scorpions, snails, crustaceans such as woodlice and land crabs, millipedes and centipedes, spiders and various worms. And we mustn’t forget the plants, without whose prior invasion of the land, none of the other migrations could have happened.

Moving from water to land involved a major redesign of every aspect of life, including breathing and reproduction. Nevertheless, a good number of thoroughgoing land animals later turned around, abandoned their hard-earned terrestrial re-tooling, and returned to the water again. Seals have only gone part way back. They show us what the intermediates might have been like, on the way to extreme cases such as whales and dugongs. Whales (including the small whales we call dolphins) and dugongs, with their close cousins, the manatees, ceased to be land creatures altogether and reverted to the full marine habits of their remote ancestors. They don’t even come ashore to breed. They do, however, still breathe air, having never developed anything equivalent to the gills of their earlier marine incarnation. Turtles went back to the sea a very long time ago and, like all vertebrate returnees to the water, they breathe air. However, they are, in one respect, less fully given back to the water than whales or dugongs, for turtles still lay their eggs on beaches.

There is evidence that all modem turtles are descended from a terrestrial ancestor which lived before most of the dinosaurs. There are two key fossils called Proganochelys quenstedti and Palaeochersis talampayensis dating from early dinosaur times, which appear to be close to the ancestry of all modem turtles and tortoise. You might wonder how we can tell whether fossil animals lived in land or in water, especially if only fragments are found. Sometimes it’s obvious. Ichthyosaurs were reptilian contemporaries of the dinosaurs, with fins and streamlined bodies. The fossils look like dolphins and they surely lived like dolphins, in the water. With turtles it is a little less obvious. One way to tell is by measuring the bones of their forelimbs.

Which of the following is TRUE about the main reason for discrimination?
