After an hour's flight one of the scientists wrote in his book, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium." None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground---using trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches. If the trees had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging into the ground. They did dig and found more gold below. They dug deeper. They found large quantities of gold. Question: Scientists went to different regions in order to search for _ . Options: A: gold B: silver C: metals D: minerals

When King John, who was the worst king that England ever had, heard of the way in which the abbot lived, he decided to stop it. So he sent for the old man and said, "Your fault is clear, and unless you can answer me three questions within two weeks, your head shall be cut off, and all your money shall be mine. Firstly, you must tell me just how long I shall live. Secondly, you must tell me how long I shall ride round the whole world, and lastly, you shall tell me what I think." The abbot went to Oxford and Cambridge for help but not one of the teachers in the great schools could. At last, sad and sorrowful, he rode towards home. Then he met his shepherd and told him all that had happened. "Cheer up, good master. I think I can help you out of your trouble." The shepherd dressed himself up with great care and looked just like the abbot. Then he went to the king. "How long shall I live?" "You will live until the day that you die, and not one day longer." "How long shall I ride round the world?" "You must rise with the sun, and you must ride with the sun until it rises again the next morning. As soon as you do that, you will find that you have ridden round the world in twenty-four hours." "What do I think?" "You think that I am the abbot. But, to tell you the truth, I am only his poor shepherd, and I come to beg your pardon for him and for me." The king laughed long. "Very well then, you have won the old abbot a free pardon from King John for this joke." Question: How long did the shepherd think the king could ride round the world? Options: A: In a single day. B: Within two weeks. C: Not until he died. D: The king could never make it.

Read the article and select the best answer. Article: Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark----alive and conscious after trading his diseased heart for a metal-and-plastic pump----convinced the press, the public and many doctors that the future had arrived. It hadn't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning the device. The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won't end the request for an artificial heart. One problem with the banned mode is that the tubes connecting it to an external power source created a passage for infection. Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient's chest. The first sample products aren't expected for another 10 or 20 years. But some people are already worrying that they'll work---and that America's overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing _ for a ly few dying patients. If such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nation's health. Question: Some people feel that _ . Options: A: artificial hearts are seldom effective B: the country should not spend so much money on artificial hearts C: the country is not spending enough money on artificial hearts D: America's health-care programs are not doing enough for the nation's health
