Knowledge and Common sense

Knowledge without common sense counts for nothing.
Today I read a news from qq.com,the news tells that four girls jumped from the sixth floor of Shanghai commercial college 's domitary for there was a fire.
I am deeply shocked by this news and aslo cause me to think a lot.
In fact,after only ten minutes when there was a fire,the firemen have arrived at the scene.but all four girls were jumped in four minutes later,not use timely ways to save themselves.lacking of common sense or knowledge?
So knowledge without common sense counts for nothing ,it is a pity that the four girls were died so young.
