Scientists have dreamed for a long time about building a 'flying train' which can float through the air above the tracks. With Maglev technology, their dreams are now a reality. Maglev trains have no wheels. Instead, powerful magnets lift them into the air and push them forward, at speeds of up to 500 km per hour.

As well as speed, Maglev has a number of advantages over other transport systems. The trains are quieter and the journey is smoother because they don't have wheels. They are also greener because they don't use fuel and so create less pollution. Right now there is only one high-speed Maglev train system in the world. It carries passengers from Shanghai city centre to the airport. However, work has started on a new, longer Maglev track in Japan. Trains will go from Tokyo to Nagoya in 40 minutes. But don't expect to ride on it on your next trip to Japan. It won't open until 2027! Then, in 2045, the line will extend to Osaka.

There is one major problem with Maglev technology: it is incredibly expensive to build the tracks. Transport planners predict that the Tokyo to Osaka line will cost 91 billion dollars. The high cost means that Maglev technology probably won't replace other forms of transport in the near future. However, the technology is still in development and somebody might find a cheaper and simpler way to build the tracks. And then, who knows? In the future, some of us might fly to work by train.

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?
