Once a city was hit by a massive earthquake. Every building fell down on the ground. Only a few were lucky enough to come out in the open while the unfortunate ones were trapped inside.
After the initial tremors stopped, all those who were trapped in the rubble cried for help. Their neighbors and relatives called police and fire-brigade but since the roads were jammed, their probability to reach the spot on time was infinitesimally small.
Luckily, two body builders resided in the same building and they were able to escape before it came crashing down. They tried to pick up heavy pieces of stones, bricks and concrete but were unable to do so because of their heavy weight. At last, they tried together and one by one, they removed all of them. Thus, they saved all the residents of the building and were awarded by the government for their courageous act.
