Scientists have long struggled to understand what lies at the planet's center.Direct

conventional Earth science.

releases heat energy as its atoms_________(15)fission-split and crash into one
another in a chain reaction.In other words,we may live on top of a gigantic, "natural"

[单项选择]

With 2005 fast becoming "the year of the natural disaster", it is time to reflect on how engineering, science and technology can play their fullest part in protecting the planet.
Long before the Asian tsunami struck, the science community predicted the particular region of Indonesia to be hit by the next big earthquake; and the engineering and technology community had developed early warning systems costing only $ 30 million. But no government in the region heeded the warnings and no early warning systems were in place. We ignored technology of the advance warnings at our peril of 100,000 victims of the tsunami.
Governments are not alone in ignoring the views of their scientific community; the public too has its doubts. Part of the reason for this lack of confidence must be down to the failure to engage them in a meaningful way about their concerns. Trust is a two-way street. Instead of claiming that everything would be rosy in the scientific garden &quo
A. scientists are doing well in predicting earthquakes
B. engineers and technologists have developed early warning systems
C. ignoring technology brought people a big loss of lives
