| The devastating effects of earthquakes
on human lives and property have encouraged the search for earthquake
prediction. This challenge remains and contemporary seismologists continue to
seek reliable methods for pinpointing the time, place and magnitude of
individual quakes. One prediction technique involves an analysis of the recurrence rates of earthquakes as indicators of future seismic activity. Earthquakes are concentrated in certain areas of the world where tectonic plates such as the Pacific Plate, the Eurasian Plate and the African Plate meet and create fault zones and it is in these areas that seismologists focus their investigations. The tectonic plate model provides another tool for earthquake prediction by calculating the accumulated strain at plate boundaries. When the strain reaches a certain magnitude the pressure must be released a A. To provide an example of a previous idea. B. To summarize the paragraph. C.

By deflation we mean a time when most prices and costs are falling. Neither in inflation nor in deflation do prices all move in the same direction or in exactly the same proportion. As a result of changes in relative prices and in total spending, the two processes of inflation and deflation cause clearly defined and typical changes in the distribution of income among economic classes.
Inflation which is not expected tends to favor debtors(f|(债务人) and profit receivers at the expense of creditors(债权人) and receivers of income which does not change.
