Hahahahaha, this is pretty shrewd way to get your homework assignment done by others. Yeah, let other people do the hardwork, let others do the thinking, then quietly take the fruit and run with it. Sad part is, this moron who calls himself coolnepali (nothing cool about him though) seems to be too darn lazy to even pose the question interestingly. It seems he just copied his instructor's question verbatim to this forum. C'mon.... you lazy ass plagiarist who can't think for himself and too lazy to do your own work... get outta here!
