Question 97, 98, 99 and 100 are based on the following reading.

A recent investigation by scientists at the U.S. Geological Survey shows that strange animal behavior might help to 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. 

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 death toll at a lower level.

the ten - kilometer radius of the epicenter

the number of people who sill die

an impending earthquake

In 1976, there was an earthquake in China

All birds and dogs in a ten - kilometer radius went wild before the quake

The Chinese have successfully predicted an earthquake and saved many lives

By observing animals behavior scientists perhaps can predict earthquake

Some animals may be able to sense an approaching earthquake
