III, Read the passage carefully then answer the questions below it:
EARTHQUAKES
One of the worst things can happen on our earth is an earthquake. When earthquakes happen near large cities, man people may be killed and many buildings are knocked down. Fires may start and do more damage than the quake itself.
Earthquakes come from a shaking of the rocks under the surface of the earth. Forces within the push against the rocks until they break. Sometimes, the earth above the break will split open.
We cannot tell when an earthquake is coming. But we do know the places on the earth where they happen most often. Much damage is stopped by building stronger buildings in these places.
As many as a million earthquakes may happen in a year. But most of them do no damage, for they happen under the sea.
