Almost a hundred thousand people were killed and half a million homes (1) destroyed as a result of an earthquake in Tokyo in 1923. The earthquake began a minute before noon (2) when many people of Tokyo were cooking their midday meals. Thousands of stoves were overturned as soon as the (3) earth began to shake. As a result, small fires broke out everywhere and (4) quickly spread. The fire engines were prevented for going to help as many of the roads had cracked open. It was impossible to use fire fighting equipment (5) because most of the water pipes had burst. Consequently, over ninety percent of the damage was caused by the (6) fire rather than by the collapse of the buildings. Most of those (7) who died were not killed in the earthquake itself but in the fires, which followed. If the earthquake had occurred (8) at night while people were sleeping, far fewer would have died
