If you were to hazard a (1) at when and where the next major earthquake will strike, there's
(2) chance that you'd be almost as accurate as the experts. The science of earthquake
prediction is still in its infancy, which is uncomfortable, considering the threat posed (3) human
civilisation. Even with vast resources at (4) disposal, often the best that scientists can do is
say that (5) odds are that an earthquake will strike where one occurred before. One reason the
chances (6) making an accurate prediction are so low is the nature (7) the forces
involved. It seems to be impossible to tell the difference between a small earthquake and a warning tremor.
Scientists need to decide whether to put lives at (8) by not issuing a warning, or constantly
issue warnings about the threat (9) an earthquake that may be ignored. In the end, the odds
seem to be (10) us solving this difficult problem any time soon.
