A recevey investigation by scientists at the US Geological survey shows that strange animal behaviour might help predict earthquakes.Investigators found such occurences in a ten-kilometor radius of epicenter of a fairly recent earthquake.Some birds screeched and flew about wildly;dogs yelped and ran around uncontrollanly.Scientists believe that animals can perceive these environmental changes as early as several days before the mishap.

In 1976,after observing animal behavior,The Chinease were able to predict a devastating earthquake .Although hundreds of thousands of people were killed,The goverment was able to evacuate millions of the other people and thus keep the death too at a lower level.

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

In Science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic molecular theory, in which gases are pictured as being made up of many small particles that are in constant motion.

A useful theory, in addition to explaining past observation, helps to predict events that have not as yet been observed. After a theory has been publicized, scientists design experiments to test the theory. If observations confirm the scientists' predictions, the theory is supported. If observations do not confirm the predictions, the scientists must search further. There may be a fault in the experiment, or the theory may have to be revised or rejected.

Science involves imagination and creative thinking as well as collecting information and performing experiments. Facts by themselves are not science. As the mathematician Jules Henri Poincare said: "Science is built with facts just as a house is built with bricks, but a collection of facts cannot be called science any more than a pile of bricks can be called a house."

Most scientists start an investigation by finding out what other scientists have learned about a particular problem. After known facts have been gathered, the scientist comes to the part of the investigation that requires considerable imagination. Possible solutions to the problem are formulated. These possible solutions are called hypotheses. In a way, any hyphthesis is a leap into the unknown.It extends the scientist's thinking beyond the known facts. The scientist plans experiments, performs calculations, and makes observations to test hypotheses. For without hypotheses, further investigation lacks purpose and direction. When hypotheses are confirmed, they are incorporated into theories.
