Help on Condition ?

Hi

   I 
couldn't understand the use of condition tag :-(. Can someone brief me on the 
same and it would be helpful, BTW obligation is usually request rt in plain 
english :-),  Why is that it has been said that Obligation are must do kind 
of activities ? just interested to know.. 

 

Thanks
