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 questions.

We are a planet of seven billion people, and this number is growing by about 370,000 people every day. This is putting a huge strain on the planet's natural resources. For many governments and environmental organizations, the race is on to drastically reduce our consumption of resources before they run out.

Water is one of our most precious resources. Our quality of life, as well as life itself, depends on the availability of clean, fresh water. It is the most widely used resource in industry, and plays a major role in energy production. Although 70 percent of the world is covered in water, only 2.5 percent of that is fresh water, and less than one percent of that freshwater is readily available to us. Yet we often overestimate how much water we have, and reduce it further through pollution or inefficient use. Some 92 percent of all fresh water used annually is dedicated to growing plants and raising animals for food. This means that if water runs out, our food supply might follow. In India, it is estimated that future water shortages could reduce grain harvests by 25%. In a country where the population exceeds 1.2 billion people and is growing rapidly every year, this is a huge concern. India, like many developing countries, is already struggling to provide for its population. While most people in developed countries can get water at the turn of a tap, nearly four billion people elsewhere lack access to safe water, according to United Nations Development Report.

Rain forests are another endangered-resource. While rain forests are critically important to humanity, they are rapidly being destroyed by human activities. The biggest cause of deforestation is conversion of forest land for agriculture. Often called the "Lungs of the Planet”, rain forests once covered 14 percent of the Earth's land surface, but this has shrunk to only six percent. Every second, an area of rain forest, the size of a football field, is destroyed at this rate. Rain forests will possibly disappear completely in less than 40 years.

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?
