 Task 3. Read the text and answer the questions below
Almost a hundred thousand people were killed and half a million
homes destroyed as a result of an earthquake in Tokyo in 1923. The
earthquake began a minute before noon when the people of Tokyo
were cooking their midday meals. Thousands of stoves were
overturned as soon as the earth began to shake. As a result, small
fires broke out everywhere and quickly spread. It was impossible to
use fire fighting equipment because most of the water pipes had
burst. Consequently, over ninety per cent of the damage was caused
by fire rather than by the collapse of buildings. If the earthquake had
occurred at night while people were sleeping, fewer people would
have died.
1. Where and when did the earthquake happen?
2. How many people were killed?
3. What were people doing when the earthquake happened?
