IX. 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.
A recent investigation by scientist at the Geological Survey shows that strange animals behavior might help predict future earthquakes. Investigators found such occurrences in a ten kilometer radius of the epicenter of a fairly recent quake. Some birds screeched and flew about wildly; dogs yelped and ran around uncontrollably. Scientists believe that animals can perceive these environmental changes as early as several days before the mishap because they have certain instincts that humans don’t possess.
In 1976 after observing animal behavior, the Chinese were able to predict a devastating quake. Although hundreds of thousands of people were killed, the government was able to evacuate millions of other people and thus keep the earth toll at a lower level
