Passage 1 Humans are forever forgetting that they can’ t control nature. Exactly 20 years ago, a Time magazine cover story announced that scientists are on the verge of being able to predict the time, place and even the size of earthquakes. "The people of quake-ravaged Kobe learned last week how wrong that assertion was." None of the methods conceived two decades ago has yet to discover a uniform warning signal that preceded all quakes, let alone any sign that would tell whether the coming tremor is mild or a killer. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist at the California Institute of Technology. So, finding one all-purpose warning sign is impossible. One reason: Quakes start deep in the earth, so scientists can’ t study them directly. If a quake precursor were found, it would still be impossible to warn humans in advance of all dangerous quakes. Places like Japan and California are riddled with hundreds, if not thousands, of minor faults. Prediction would be less important if scientists could easily build structures to withstand tremors. While seismic engineering has improved dramatically in the past 10 to 15 years, every new quake reveals unexpected weaknesses in "quake-resistant" structures, says Terry Tullis, a geophysicist at Brown University. In Kobe, for example, a highway that opened only last year was damaged. In the Northridge earthquake, on the other hand, well-built structures generally did not collapse. A recent report in science adds yet more anxiety about life on the faulty lines. Researchers ran computer simulations to see how quake-resistant buildings would fare in a moderate-size tremor, taking into account that much of a quakes energy travels in a large "pulse" of focused shaking. The results: Both steel-frame buildings and buildings that sit on insulating rubber pads suffered severe damage. More research will help experts design stronger structures and possibly find quake precursors. But it is still a certainty that the next earthquakes will prove once again that every fault cannot be monitored and every highway cannot be completely quake-proofed.

If the population were (21) evenly over the earth’ s surface there would be about 50 people to the square mile; but there are vast areas of desert and mountain and tropical forest (22) are uninhabited, (23) at the other (24) , in the great cities millions may live within a few square miles. (25) of the world’ s population is concentrated on only a small (26) of the earth’ s land surface, in the rich valleys and (27) plains, because people up to the present time have (28) to congregate in place where the climate and soil make it easy to grow food and obtain shelter. A (29) world population and the discoveries of science (30) this pattern of distribution in the future. As men slowly learn to master diseases, control floods, prevent famines, and stop wars, fewer people die every year; and in (31) the population of the world is steadily (32) .
