Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock. What have spread diseases? A) Disease-sleeping sickness. B) Measles. C) Improved communications. D) Malaria.

Once a father was seated at the dinner table with his wife and children. A good friend who had come to visit was eating with them. While they were sitting there the clock struck twelve,and the stranger saw the door open and a very pale little child dressed in snow-white clothes come in. It neither looked around,nor did it speak,but went straight into the next room. Soon afterwards it came back,and just as silently went out of the door again. On the second and an the third day it came back in exactly the same manner. Then the stranger finally asked the father, whose beautiful child it was that went into the next room every day at noon. "I did not see it,"he said,adding that he did not know whose child it might be. The next day when it again came,the stranger pointed it out to the father, but the latter did not see it,nor did the mother and the children see anything. Then the stranger got up,went to the door of the room,opened it a little,and looked in. There he saw the child sitting on the floor, and busily digging and rooting about in the cracks in the floor. When it saw the stranger, it disappeared. He now told what he had seen and described the child exactly.Then the mother recog- nized it, and said,"Oh,it is my dear child who died four weeks ago." They ripped up the floor and found two farthings which the child had once received from its mother to give to a poor man. It,however, had thought,"with that money you can buy yourself a piece of zwieback,"and had kept the farthings,hiding them in the cracks in the floor.www.ks5u.com Therefore it had had no rest in its grave,and had come every day at noon to look for these farthings. Then the parents gave the money to a poor man,and after that the child was never seen again. what would be best title for the passage?
